If you know your Fourth-Generation Camaros, then you'll notice that there's just a pipe where there's usually a muffler in this photo. It's designed that way. It's SLP's "Loud Mouth" exhaust system, which dumps the muffler for, well, nothing. Actually, there's an expansion chamber upstream, which helps quell backfires and pops when you get off the throttle, but basically, there's no noise muffling going on here. Your car will sound like Kurt Johnson's Pro Stock Cavalier with this system...And your neighbors will hate you for it!
