Removing stock cat-back???

TheBusher · July 28th, 2007, 01:13 PM

I want to get SLP LM2 in the near future, but until then I was thinking about possibly just removing my stock cat-back. What do you guys think??? Would it be too loud, or just sound like crap, or any other reasons you guys can think of not to do it???

I think it would sound like crap when you let off the gas and also there wouldn't be enough back pressure i dont think.

When I took mine off I lost a lot of low end power and it really does sound like crap when you let off the gas....sounds nasty when you get on it though, but it just gets really annoying to hear it popping constantly when you let off the gas.

What kind of midpipe are you running because my magnapacks popped alot with an o/r h but dont with my o/r x

i have a mac o/r h pipe and it pops alot. with x pipes there is supposed to be less echoing so it sounds better on mufflers like magnapacks or lms

...But it is deeper with a H pipe. If your car is popping alot it is time to invest in a tuner.

It does sound awesome when you get on it. Loud as anything I knocked sockets and such off of stuff in my garage. I think I made my gf temperaraly deaf, but it does sound like ass when you get off of it. I didn't drive it like that though so I can't say anything for loss of power.
