Smelly,
It isn't that expensive, kinda like 6 bucks or less i think for a whole kit, anyway if u do get the muffler off and decide u want to pull the engine a bit and get the heater boxes off u can get J tubes to replace them, that way all the heat goes out the back and doesn't linger. Just my opinion heheheh... But i will tell you, just beacause u get a muffler kit and a muffler it will be quite, because i thought the same thing and nope lol.. But is quiter than the one i pulled off, lol. i was thinkin about pulling mine off after soaking them everyday and putting a stinger on it lol.. But don't know yet lol
