Evo 6, E92 320d
Right, so i've had the 172 since sunday and at 2k and 3k i get a vibration-tinny sound from the backbox, i havn't ruled out the heatshield yet till i get it on a ramp this weekend. I've also noticed when i put my foot down i get a sound like somethings blowing, manifold is on tight and the exhaust system itself appears to be quite new. Is it possible its just a shitty exhaust?
