Ok, so, I've looked around for some time, and haven't seen these questions asked...

For the stage 2 map, what does Cobb consider a turbo-back exhaust? Is it tuned for an open test pipe or high flow cat? Has anyone used this map with just a cat-back exhaust?

Also, with their SF intake tune, is that tuned for the Cobb suction pipe with the SF intake attached to it? Does the SF intake come with a heat shield to prevent the erratic idle issue?

Is the stage 2 map safe with an upgraded intercooler or intercooler pipes?

This may sound like I'm nit picking, but I've had this car for a week and I don't wanna screw it up, haha.

Thanks in advance!

The turbo-back is a down pipe, cat section (high flow or test), midpipe, and muffler section. Some people say you can use the stage 2 with just a cat-back, however I wouldn't suggest it. You can use the stage one with the cat-back. An upgraded intercooler would put you into a stage 3 map, but you could use the stage 2 map, but will not net as much power. Intercooler pipes are usable on any map and so is the COBB suction pipe, i.e. turbo inlet pipe. Any intake that changes the MAF section of the intake should not be used unless it is COBB's SF intake and your running the stage 2 map with a TB exhaust.

Hope this helps......

Cobbs new Stage 1 version map says a catback is fine. Therefore I can only assume that an actual TBE is needed to get the full performance out of the Stage 2 map.

Wow, I must be blind. I read over those map notes a couple times and missed the CBE note...

Thanks for the note about always being able to use IC pipes.

What about erratic idle issues with the SF?

^ Don't have one so I can't say. I would just get a perrin drop-in which can be used on any map. The stock intake flows very well. Replacing the turbo inlet section of it makes the biggest difference as it is much smoother that the stock piece. Other intakes, the COBB SF, Injen, AEM, etc. change the MAF tube size which tricks the MAF as it was not made for a larger tube. This inturns leans the car out, which is how they make power. With an AP, it leans the car out on every map, which makes added a large MAF pipe dangerous. If you look at COBB's stage two notes the one with the COBB SF doesn't make any more power than the one with-out. Hence the resoning to leave the intake stock or just get the perrin drop in. (Aviod the works drop in as it leans the car out....i guess)

Thanks for the info.

So, the Cobb inlet tube and a Perrin drop-in should be good with any map?

yes. All Except the Stage2+SF 93or91 Octane map. That map specifys it is to be used with the Cobb SF intake

Ok, thanks for clearing up the confusion!

OK- for the MR CDN where can I get the Perrin maps? Do I have to buy COBB AP from Perrin to to get PERRIN maps? or can someone upload them for us? we should have a file which contains all of the maps hosted somewhere....just a thought....

^ Perrin Maps are not free, they charge something like $150 each for them. If you buy your parts from them they currently are giving the proper map with it. I do not think they would be happy to see someone "sharing" their maps. However, I do agree we should have a place to keep custom maps that people are starting to make.

So to be clear, the turbo inlet pipe is NOT replaced by any of the intakes on the market right? They're two separate pieces?

^ Yes, 2 different pieces

Hi Travis,
I was wondering if I would be able to run the Stage2+AEM map if I'm running the AEM intake, the AMS O2 Eliminator 3" downpipe, and a RRE rally cat (basically a test pipe), and the stock catback. Does replacing the O2 housing, the DP, and removing the cat open the exhaust up enough to run this map? I want to get most amount air flow I can while trying to keep the car stealthy and quite with the stock catback. What do you think?

Typically the downpipe is the restrictive portion of the exhaust and is the determining factor when choosing stage1 or stage2. I would think that a stage2 map for the AEM intake would be perfectly appropriate for your application.

so you can run stage 2 with that setup (or similar) + stock exhaust. nice i may do this for a while since im still debating on which catback i want.

so if i understand correctly, unless you have a full turboback exhaust system, for example, i only have a downpipe, then i should be running stage 1 still, not stage 2 cobb correct?

Dude...read 2 posts up! This is from Cobb...

Thanks, I'll keep that in mind since it looks like i can get the Cobb inlet and run the stage 2 (i have an intake already but haven't installed it yet due to needing a custom tune).

Now the hard part is to choose whether to buy the Perrin downpipe/200 cell hi flow cat combined one peice, buy the AMS O2/DP and a high flow cat (vibrant or possibly MilSpec 100 cell race cat), or keep the stock cat and wait for QTP to finish their electronic cutout for the Evo X ( I emailed them and they said they're targeting a summer release)

What do you guys think?

P.S. the cat back has already been decided--its the AMS dual

My personal opinion is to have all the same exhaust components from the same vendor. That said I would go with AMS. Do you really want Company A's downpipe, Company B's test pipe/HF cat, and AMS CBE?

I wouldn't, but this is only my opinion.

Hey thanks for your input. To answer your question, nope i have no reservations about mixing the parts of different manufacturers to get the perfect combination of performance, sound, looks, and honestly most important to me at this point, flexibility. I think I'm leaning heavily towards waiting for QTP to finish up their electronic cutout. i can live with just the CBE for a while

P.S. I was at the Swap meet AMS had Sunday, and Dan fired up the white Evo X that has the dual on it and it's currently wide open (has the turboback with no restricor plates on the dual) and that thing is LOUD. Sounds nice, but it's race car, cops pull you over, not ideal for daily driving LOUD. That's why flexibility is important to me since this car is my only vehicle and it serves several purposes. I always want the best of both worlds when I'm able to. Between flipping a switch on the electronic cutout, and being able to tune the sound of the AMS dual (when the cutout is closed obviously) I think that combo will work!

i can understand that.

Good luck
