Want opinions on the best sounding exhaust system. I am looking for something you can hear and not quiet but nothing that is obnoxious and sounds like a weedeater on crack. Oh by the way I have a MSP so I need a 3.0 cat back to get rid of back pressure I know all the brands but what is the best I was leaning towards GReddy but I have heard it is quiet.....

 

I don't think the GReddy is as quiet as the Racing Beat but still a good exhaust. Alot of people on this forum will swear by both. And the GReddy is a quality system. Search in archives for a idea who has what. Good luck, Dav

 

Go to msprotege.com and click on "Forum Index," then click Mazdaspeed pro, then click MSP engine & performance. There's a sticky forum on there where you can listen to peoples exhausts. The first one is the best, but I also haven't heard all of them either.

 

i personally love that new GHL motorsports FULL 3" turb back exhaust. That would be the ONLY way to go.

The stock S-pipe is horribly restrictive and this new unit is very well designed. I figured you'd get at least 10-15whp and hold an extra 2psi of boost all the way to redline with it.

get it and the BEGi FMIC from protegegarage.com and I'll install it all for you and we'll go dyno together!
