ask badfish. He was running loudmouth with an o/r pipe and that thing was rediculously loud. I think at 2,000 RPM he was louder than my GT with an xpipe and straights.

i swear those "Resonators" on the loudmouths are nothing more than blowhorns.....

 

Dude, SLP Loudmouth and running catless is enough to give old people heartattacks, i think the only thing louder is open headers. ROFL

WHen i first got my GT i liked the sound but wanted to hear it more. I got a 3inch x-pipe welded into the stock piping, Mufflers have been removed and it hits the 2+1/4 again over the rear axels and comes out to 3.5in chrome angled tips.
The sound is as good as i could have hoped for. When idling it has a pretty mean purr, lower RPM's it sounds nice and mean still, but doesent get overly loud. When i crank it up to 4-6krpm it really gets loud... loud enough to scare ricers away.

the good thing is i can cruise to and from home down my culdesac at 2am and not worry about waking anyone up unless i want to.... i can still set off car alarms from 15-20 feet away when i want though.

The SLP with o/r is LOUD AS **** ALL THE DAMN TIME. <laugh> My advise it to check out something like borla if you want a mean sound without yer neighbors screaming at you every time they hear you. <laugh>
