think its a wepr decat and it doesnt fit to my exhaust system. it is the right shape to fit on but instead of aligning with the holes from the exhaust system for example 1 hole of the decat sits between 2 holes on tyhe system if you get what i mean. dunno if its ment to fit a gt or somethin because i know the exhaust system on them is different ?? help appreciated as the one thats on is about to snap lol.
