Just got my new cat back slp loudmouth system installed on my 2001 ss.
and if you have an LS1 and dont have SLP loudmouth exhaust, i hope you die a horrible death. because it just sounds so dam good, it sounds mean as hell. nothing can compare. i acctually pee'd alittle bit in my pants when i first cranked her up its worth every penny

 

I hear ya! I felt the same when I first turned mine on. Even tough I have an LT1 lol.

 

agree 100%. I love mine. My wife got it for me for my birthday. She's greet. Hell, just the other day it made one of my neighbor kids cry when I started it up and gave it a little rev. Didn't care for the brat anyways. Go with some long tubes and no cats and you will really hear something mean.

 

Yea, just wait untill you add longtubes... Then your liable to Sh*t your pants

 

I'm trying to decide between the SLP Loudmouth and the GMMG myself. From what I've heard in videos and stuff both sound fantastic...but I've not heard either in person.

So I'm not sure which way to go....obviously the SLP is a lot cheaper.

SLPs are the way to go man.

 

That def. sounds badass.

If I recall the Loudmouth is emissions legal, correct?

 

emissions, we don't need no stinking emissions. I believe they are but usually isn't a big deal. Have visual inspection every year and have yet had a problem with my setup.

 

They hook us up to a sniffer, so it would have to pass that test. I think it would be ok though.

 

you should pass the sniffer test fine as long as you have your cats and o2's connected. Cat back shouldn't effect smog test at all, it is just routing the spent gases out of the car better. Get the loudmouth if you are in the market for exhaust that is loud as it is. Ideally I would of got corsa or magnaflow as either sounds good but really am happy with loudmouth, no complaints.
