i need to know what the loudest exhaust is to get on a 2008 gt500. its a weekend car so i dont care how loud it is. i do want it to be the loudest on the street. also what am i suposed to be looking for in pipes to make them loud?

LT's, o/r mid pipe either h or x, and a straight thru muffler delete such as loudmouths, boomtubes or pypes muffler deletes. i would suggest boomtubes, they sound the best out of those 3 IMO.

to make it loud you basically need to make it breath better: LT's instead of the stock shorty's, o/r to get rid of the cats, and straight thru mufflers are the loudest. and the LT's you can go w/ 1 3/4 since you are SC'd.

there a special king of longtubes i should look for?

idk much about the gt500 specifically, but there are ARH and borla, ARH are supposed to be top quality, and i think kooks makes for the gt500 too and they are top quality as well.

I put a Borla cat-back exhaust system on my 2007 GT 500 and it sounds great! The local speed shop recommended them to me because he said their were very good quality and would have the mellow, throaty sound I wanted. Also, the Shelby Supersnakes will have Borlas on them, so that says a lot since the Shelby auto engineers picked Borla.

Get some long tube headers( Kooks or Bassani)an off road H-Pipe from MRT, SLP loud mouths and you will be happy , your neighbors may not like you much though. A good exhaust shop can can fab it all up i prefer the H over the X pipe it has a deeper tone. But it will cost you a bit to install.Or you can't go wrong with the full Bassani or Kooks off road system. As long as you have no troble codes and they cant look under your car( under a bay for example)you will pass inspection. Youwillneed to tuneyour carwith a handheld running off road exhaust, to get the most power and no trouble codes. If you leave the cats on it probobly will not be as loud as you want.

I'm running Kooks with cats 3" all the way back. Using there X pipe also. I would at the least go to SHM and get a cold air intake and the pulley kit and tune. The boost you have now will blead off due to the free flowing exhaust which makes the car sound not so good.

I can say personally I would like to quiet mine down and it's only a cruise or show car or the track. It's louder than most cars at the track and mine has cats and mufflers. We spent one year building the car but ended up with a car wickedfast with a sound that is mind blowing!

Hope some of this helps. Yes had the SLP loud mounths but hated them.

I have the Cervini's C-series kit that is the side pipes, it has mufflers, but when I put on the O/R pypes h pipe (no cats), it was so loud I couldn't hear myself think...

For ease, you could just do SLP LMs and an o/r h pipe and of course LT headers
