I recently replaced my gundo bypass with a fabspeed Maxflow muffler along with fabspeed headers, what a big mistake my exhaust sounds super super quiet. I need to wake my car back up,,What am missing sport cats or cat bypass??

Let it burn in a bit more, like 800-1000 miles, then see if the mufflers wake up.

 

Add the x-pipe.

 

Anyone have a sound clip?
X pipe with or without cats?

 

I done put about 3000 miles on the exhaust..

 

i have the full fabspeed exhaust: intake, headers, xpipe cats, and mufflers. it's by no means loud, which isnt a bad thing. it sounds more refined instead of loud and annoying.

 

i have fabspeed high flow mufflers and 200 cel cats and when u get on it it has awesome noise and rumble. I have fabspeed intake too.

 

Gundo's, high flow cats and X51 headers. The engine growls, you'll love it!

 

killacam, you have a sound clip you can text me at 973-650-6170

 

NJGT3 - I am sorry to hear that you are un-happy with the noise output of your current exhaust system. If you are looking to wake the car up, complete your system with this catbypass x-pipe, I can almost guarantee this is the missing link to the sound you are going for.

I thought the MaxFlow was also pretty quite from all the youtube videos Iv watched. So I went with the Fabspeed SuperCup exhaust. Should be here in a couple weeks I'll post up when I get it.
