i have a 06 subaru wrx TR. i put in a hi-power hks exhaust a few months ago. i love the exhaust but now i have a problem with it. i think the exhaust is hitting something under my car. everytime i have in in low rpm theres like a rattling music on the left side.
Does anyone else have this problem? if anyone can please help. i looked under the car and i cant find the problem. thanks.
