so some people have been saying that the m55 mufflers are unreasonably loud. although it is pretty loud, i dont think its unreasonably loud until after 3k or 4k rpm. at idle and at 1k-2k rpm the tone is pretty okay. above that then it gets pretty wild. one thing that i really dont like about it is that it sags really low and now i gotta get the hangers bent before i scrape my tailpipes everywhere. other than that, its a pretty decent exhaust setup. i will have a video with sound up soon. my current exhaust mods are stock headers with o/r hpipe and the m55 mufflers.
