4 Inch Mufflex
I just ordered my 4 inch mufflex catback with the spintech muffler. I will be taking lots of pics after I finish going from the headers to the catback. If anyone is interested then I will post as soon as I start this project. I just can't wait till its gets here.

I built my own 4" system with a spintech stainless steel muffler. If you look down the thread (my exhaust picture) you can see some pictures of my exhaust in the works. I wanted to purchase the Mufflex system but my car was not a "cat back" and did not want to spend the extra money for a bunch of stuff I was not going to use and have to rework. I ended up just building mine from u-bends and straight tubing.
Let me know how yours fits and can't wait to see some pictures.

Yeah i have the 3.5" mufflex, with the single out spintech. I really like the hidden tail pipe. You can still see it though from behind. Looks kinda stock just a lot bigger lol. I never really found any other tail pipes that looked right long term.
You will love the sound has a nice deep bass to it at idle. The sound is not to loud or to quite just right to me. The quality of the pipes and muffler is very good. Although there not stainless the metal is pretty thick.

Re: 4 Inch Mufflex
Can't wait to see the pics. Going to do the same as Comp778 and build my own 4 inch system using a Spintech muffler. Really liked the sound of my old single 3 inch with the Pro Shootout muffler. The dual 3 inch bullets right now are just too freakin loud.

Re: 4 Inch Mufflex
Just thought I would post what my exhaust sounds like now and then tomorrow I will post the new exhaust sound. This is a dual 2 1/2 in exhaust with bullet mufflers.
Excuse the squeaky belt and the wind noise lol

Re: 4 Inch Mufflex
So which spintech muffler did you go with? The street version or the race? How loud is it compared to the old setup? Sounds good

I actually had pretty good ground clearence with the true duals, not as good as a single exhaust but pretty damn good. The 4 inch is also really good clearence.

Re: 4 Inch Mufflex
Wow t thought you would have been lower but that looks good and sounds alot better than the duals they were to raspy but i think they would have sounded alot better with an x-pipe
