This thread is teh funny!! lol. Back on topic. Mainstream built my exhaust, It's a 2.5 inch header back with a Magnaflow resonator a few mandrel bends and a magnaflow straight through muffler. It tucks nicely up in the stock location and still looks low profile. It's an oval cannister so it hides under the bumper nicely and looks clean. It's a little on the loud side but it has a nice sound. I've only heard good things about the sound from others. Only complaint from some is that it's too loud, but hey at wot on the way to 10k rpm's I expect it to be loud. Good luck on your decision. Also, don't buy knock offs.
