Just did straight pipes, resonator delete with a Meistershaft Exhaust, I personally think it sounds amazing, real deep tone with a growl..But to my taste louder the better..

How much did people pay for your xpipe instal? Where should we order the part?

Not all x-pipes are created equal. I've seen people lose hp after x-pipe installations. The GT-Pro x-pipe seems to be very high quality and well thought/engineered after a lot of testing. The C63 guys are reporting great results. Also, the RennTech Sound pipe is another excellent option, but it will raise the sound considerably. You should maybe talk to a few people who had different x-pipes installed and see how they like it.

TTM removed my 2ndry cats and did pipe from primary hi flow cats to resonator and it sounds sick! Not loud and under regular driving you can barely tell until u go past mid throttle it sounds INSANE is the only word for it !

I tried to get mine installed at a local, well respected muffler shop and they wouldn't touch it. Started talking about the EPA and o2 sensors... I kinda zoned them out after they said no.

Updates? I'm really interested in your setup.

Not yet, I have been buried past few weeks, however I'm getting caught up, so I have to give one of the guys a call so we can get together to build the first one for everyone here!!

Any updates?

Brian GT PRO

No not really, we have been finishing up some C63 developments that had quite a bit more hurdles than we anticipated, but once we get that ironed, I will be looking for a test car
