Just to give a heads up to people and I have a few questions to ask too.

Custom Performance Engineering is working on a downpipe, test pipe and a full catback system. We are looking to get those out in the coming weeks.

I have attached a few images of the downpipe and test pipe. You can tell that this is a Ralliart if you look at the front suspension on one of the photos (steel control arms vs the aluminum on the evo)
Sorry for the blurriness but those are prototypes and not very pretty to begin with.

Also wrapping up some stuff for the exhaust which as we stand now will be with dual tips.

As far as some questions for the owners:

How do people feel about single exit exhausts, and single exit race exhaust (no muffler, maybe just resonator).. Not sure if thats something people want.

Eitherway - just wanted to introduce the company, and see what people want.

We are planning on developing other parts for the car as well and will bring updates on those as well!

Thanks for listening, and please ask any questions if you have them.

Looks nice and I love the idea of quad tips on a evo. as far as raceing single exhaust I like loud but some that live in cali can't use them for they are to loud. I would try to do a titanium pipeing and a carbon muff with ti tips. I love that look just IMHO

P.S. welcome aboard

Specialty X to my opinion has created the best looking tips soo far.

Yea I agree But I wish they were ti.

Yea I agree But I wish they were ti.

what's wrong with the material they are currently using? Will it rust easily, or is it weight?

I think they just want Ti tips for the looks

Alot of people want titanium exhausts, and while I understand why - its just not always easy to make them - or profitable.

Quality titanium is not hard to find in the US - its the pricing. This is the issue with the GTR owners who want products made here, instead of getting them shipped from Japan, yet anyone who makes it here will only be able to undercut the Japaneese companies by so much while keeping barely any margins, but owners tend to think that if its in the same country then itll be alot cheaper than in Japan.

Titanium is hard to work with - CNC benders dont always like the material, and you can only bend it so far before you have to start doing cutting and welding, which adds time and cost to the product (ALOT of time).

These are the issues at least that we have run into - just from experience.

Tips - there are always tip concerns on exhausts and a wide array of opinions - its hard to make a choice for a product.
We were thinking of even offering the exhaust without tips - the piping is centered in the opening and you could just get your own set of tips and have an exhaust shop tack them on there.

Its hard to have a huge variation on a production line - we try our best to select the best possible compromise and go with that, custom, or more expensive items (Ti tips), are hard to do and slows things down, and makes the product more expensive in the end.

I think they just were refering to the burned titanium looking tips. Make a quad with those and i'll buy :)

:amen: and if possable carbon muffs. for tuner inmind I would really try to keep the Exhaust down to around 20 pounds or so I would not go over about 25 for that is to heavy IMO

that would be sweet... but to tell you the truth it seems like there are so many Ti tipped systems out there.

Hey what about a turbo manifold you guys going to make one

Here is a little more of what we are finishing..

Mufflers will be added to this to complete our dual exhaust. We are considering having a dual race exhaust (which would look like this) or a single race for weight saving.

Expect the exhaust in two weeks or so, downpipes/test pipes may come earlier.

carbon muffs sound nice. However, what if you bottom out somwhere and hit your muffler? Carbon will just crack.

I like that muffler-less design... does it sound different or any louder then the one that was one my car?

sounds pretty nice form inside.. cant tell for sure on how good of a sound it is as it wasnt finished yet when riding around on it in and out of the shop.

There is that debate.. whether you make the exhaust straight through and single exit for lightest weight. Or straight through and dual exit for looks - but thats not very purpose driven.

Depends on what people want!

This is what the exhaust looks like with the mufflers.

These are made to our spec and sound very nice - sound clips should follow soon as well as the first production run.

really? 5 lbs? just dont eat dinner... or take a fat dump before you drive :p

exhaust looks clean man... Quad tips might be a bit much on an evo... need to see one... but ti tips FTW ;p

how i live in virginia nice! cp-e. looks good hp?trQ? sound?

At the momement we are wrapping up exhaust designs and such, dyno numbers to come soon!

Video should be available this weekend!

Will be similar to our EvoX exhaust thats in production currently: (full turbo back exhaust)

A quick run through photoshop and here's the (horrible) results,

Quad TI ftw :shades:

Here are some photos of our new Ralliart Exhaust. We had it running as a full turboback with our test pipe and downpipe. No cats, no CELs. The perceived gains seemed significant and the sound gives the car a whole new attitude.

The mufflers are made to our complete spec by our supplier in california. As far as the rest of the exhaust - its designed, prototyped and manufactured in house.

Designed completely in a CAD environment, bent on CNC benders, fixtured, and hand TIG welded (for now by hand, future will have robots help out) - and out the door directly from us.

Ill let the photos and some videos do the talking. We expect to be done with the first production batch in about two weeks - the downpipes/test pipes will be available slightly earlier.

Also currently working on getting an intake done for the Ralliart.

Ill get some pics up as soon as I get it to look more like an intake rather than pieces of metal.

Working to finish the first production batch of our Ralliart dual exhausts!
Its nice to finally get to this point after finalizing design and fixturing


Will be taking orders later this week!

preorder finally up!

You guys looking into any tuning like the standbacks or flashes for the Ralliarts?

Flashing is definitely on the list one way or another.

I am working with ECUFlash for tuning and we are developing an easy flash tool thats reliable and does things right. In a month we should have a clearer roadmap for the products.

All in stock and ready to ship - find our post in the vendor section!

Finally! The dyno is up and running and I got on it first thing and ran the Ralliart with our parts to get some power numbers out of it.

A few things worth mentioning:

A dyno is a scientific tuning tool and gains of performance parts are measured in reference to how the car runs stock on the same dyno - normally called a Baseline. You cannot compare numbers between different dynos as their physical location and characteristics are different. We have a full out AWD Coupled Mustang Dyno - and these dynos tend to read a little lower than most others. Again - you cannot compare different dynos to each other.

Before anything was done to the vehicle - I made a few runs under the same conditions with the car in completely stock form. The car was allowed to cool down to a normal running temperature and runs were made in the same gear every time.

Of all the runs in stock form, I took the ones that were consistently close to one another and picked one to be the baseline.

All the numbers that I will be posting - are in line with the scientific method of experimentation - meaning I can repeat the runs and achieve nearly the same numbers granted the weather conditions are the same.

All the tests were done within a two day window with the weather being nearly the same.

The gains might not be mindblowingly impressive - but they are real, and as accurate as they can be. We don't exaggerate, or try to trick the car in any way to make it run better to squeeze better gains out of it.

Here is the Baseline. You can see it peaks at 220 AWTQ and 181 AWHP

http://farm4.static.flickr.com/3582/3357643312_60e3bb803a_o.jpg

To begin, I tested our Quickpower test pipe - the non-catted version.

I did not get any check engine lights because of the built in fix for that. The car ran great with minimal noise increase. The rest of configuration was stock.

Stock Downpipe
- Quickpower Testpipe
Stock Exhaust

Quickpower Run - SOLID line
Baseline run - Dashed line

You can see that the peak numbers did not change much - they are within a resonable margin of error. The gains with the Quickpower pipe are past 4500RPM (and as with the all the exhaust components).

You can see that there is a gain of about 8-11 AWHP/AWTQ at the top end where the Solid line (QP run) starts to diverge from the Dotted (Baseline).

http://farm4.static.flickr.com/3580/3356825939_c81cafdc66_o.jpg

After the Quickpower pipe, threw on the stock catalytic converters and put on our Downpipe.

Just as a few other companies reported - upgrading ONLY the downpipe - yeilds no gains.

HOWEVER! I tried a different configuration where I ran the Downpipe AND the Quickpower pipe - and here I gained some power over JUST running the Quickpower tets pipe.

- cp-e Downpipe
- Quickpower Testpipe
Stock Exhaust

Quickpower/Downpipe Run - SOLID line
Baseline run - Dashed line

As you can see in the graph - once again the gains are past 4500RPM, the PEAK numbers dont change much - but the gains up top are visibly bigger with the Downpipe/Quickpower combo versus just the Quickpower.

I got about 12-15 AWHP/AWTQ worth of power with the Downpipe/Quickpower Combo.

http://farm4.static.flickr.com/3663/3357643896_bd391fe293_o.jpg

Good info, thanks for the updates.

After running the previous tests - I reverted everything back to stock and then went on to install the Dual Cat-back Exhaust.

The Catback sounds great, but it seems that the stock catalytic converters really create that bottleneck, so regardless of what you put after them - you are still limited in flow and power.

Stock Downpipe
Stock Cats
- cp-e Dual CBE Exhaust

CBE Run - SOLID line
Baseline run - Dashed line

Once again, the PEAK numbers dont change and there are nominal gains up top.. About 8-10 AWHP/AWTQ Gains

http://farm4.static.flickr.com/3470/3357643760_20e1213698_o.jpg

A quick run through photoshop and here's the (horrible) results,

Quad TI ftw :shades:


:rock: I love quad tips on the X, dunno why.

Now this is what I've been waiting for.

After a day and half of full work on swapping hot parts and turning wrenches - I finally got to test the full TurboBack setup. This is where the power is! A nice sounding free flowing exhaust.

- cp-e downpipe
- cp-e QuickPower pipe
- cp-e CBE

TBE Run - SOLID line
Baseline run - Dashed line

At 4800RPM the power/torque curves start to seriously diverge. You see that the new Torque curve starts to follow the old Baseline Horsepower curve. The new Horsepower curve keeps climing way beyond what it used to be.

Here we see about a 30 AWTQ gain and nearly 40AWHP gain in the top end AND constantly climbing HP curve and a flatter TQ curve.

This truly made my week and indeed the incing on the cake after my dyno trials with the ralliart. Saving the best for last.

The sound is incredible - hearing the exhaust sound bounce off the walls and overpower the whine of the dyno really changes the attitude and impression of the car. The sound finally fits the looks.

Heres what I am talking about

http://farm4.static.flickr.com/3656/3357643606_a879d15dc6_o.jpg

I'd be interested in a single exhaust w/ lower price tag. Seems allot of these exhausts are just as expensive as Evo X kits.

well obviously the full tbe is the best bang for the buck. But if yer on kind of a budget, the quick power would be a good cheap way to remove some restriction w/o too much noise? or the catback which is more expensive w/ louder sound but perfectly legal to run a better idea? could always up-grade to the full tbe down the road anyway.

I'd be interested in a single exhaust w/ lower price tag. Seems allot of these exhausts are just as expensive as Evo X kits.

that is the price of getting some thick durable stainless steel, custom mufflers (for cp-e), and some great in-house engineering/manufacturing... if these prices scare you, check out the mazdaspeed and bmw communities... they are a little worse

no dosn't scare at all, figured that's what it would cost for an EVO. Shit's always been expensive for that. This is supposed to be the low-budget car, parts are just as expensive, what's the point?

It costs them just as much to make this exhaust as the evo x exhaust... so the price reflects it. You are going to see a lot of things that are the same price from various manufacturers due a lot of car being the same... with only minor differences. To me, budget cars are hondas... not RA's or WRX's

Yes EvoX2NR is right..

Pricing in this case doesnt come from the type of car its going on but from Manufacturing and Engineering costs and high quality materials.

We already have the cheaper of exhaust for the vehicles..

Let me know if you have any more questions!

sure thing, yer catback is less expensive then ultimate racing which does not look too good IMO. I would totally consider yer catback if it's not too loud. Or maybe just the quickpower hfc in the stock exhaust.
