if you want loud, but a GOOD loud sound, i reccomend pypes offroad h pipe and steeda axlebacks. here: http://youtube.com/watch?v=zls1BxwF06U


or, if you prefer the screaming power v8 sound, may i reccomend, offroad x pipe, and mac boomtubes:

both are quite loud, but extremely pleasant, very very pleasing to the ear. the first one is my favorite.

An offroad x pipe with Borla/FRPP Stingers will be really loud and in my opinion would sound better than SLP LMs. The Stingers are flow through mufflers that will give the exhaust a better tone compared to the loudmouths and boomtubes without quieting it down much. Also, another loud, and good sounding setup is an offroad x with the Pypes mid-muffler system. If you are trying to decide between SLP and Boomtubes, the Boomtubes sound better.

Off road X-pipe two resonators and mufflers deletes sound like this.

What about an off road X pipe/H pipe with a custom mid muffler kit? That's what I've got and it's freakin loud!

4 cams and Flowmasters are the right kind of sound .

Ahh PROMETHEUS! ;-) Yup, sounds good. Resonators make all the diff. Thinking about switching to an O/R H. If you want rasp...then go X, for a deeper tone go H. Any straight pipe is going to give you trumpeting though.
