Ark rattle issue? suggestions?
So i just installed my Stillen Headers, Berk Hi-Flows, and ARk exhaust... it sounds like the passenger side canister in the back is bumping against something... anyone else have this issue? any ideas?
also, sometimes i can hear like a whistle sound where the x pipe is in the exhaust is that normal?
