recently baught a rolled out kam racing back box then gota 2nd hand str8 threw pipe wich for some reason sat low to the floor. anyway today my brand new hoffman race pipe came all fis nicely accept the fact it VIBRATES/RATTLES on the body of my car which is exremely annoying and noticable. why is this? is it because my center exhaut rubber is stretched allowing the exhaust to have abit of play? Also it doesnt seem to be very loud but i think thats simply because i have a stanard mani atm. help required many thanks
