Hey guys picking up my 2011 X this Saturday I want to order my exhaust by Sunday I came down to the Greddy Ti-C single and the ETS single 3.5" for the car my plans are to make about 400HP nothing more I would like to make 400Whp if possible with my budget while I'm in school. I just wanted to see which you would recommend? I don't care about how loud it is as long as get the most performance and the least drone. I want to do it testpipe and back don't want to touch the downpipe until I get the money for a tune. And one last question dealership wise most dealers say if you don't touch the downpipe they wont say anything is this true?
Thank you
Thank you
