I was just joking around.. yeah I dunno if they have a compelte exhaust kit for your long bed, but screw it! I'll never throw away my money again buying some exhaust "system" or "kit" now that I know all you need is a muffler and a turndown :crazy:
Anyways, the sound is mainly going to come from the muffler, and you have hundreds of mufflers to choose from. I have had gibson, flowmaster, and dynomax bullet (current) and they were all nice but I like the dynomax the best. Check out
www.ls1sounds.com , lots of exhaust sound clips there.. but keep in mind that all those cars/trucks are different and could be stock/highly modified.
How loud do you want it to be outside? On a scale from 1-10... like a low rumble or a loud ass cracking bark? Look around and listen to some clips... you can get just about any muffler for really cheap online. You said you wanted your exhaust dumped, so just get a 3" pipe with a turndown under the bed, an exhaust shop shouldn't charge you more than $30 for a piece of bent metal.
If all else fails... just get an eletric exhaust cutout.
