mate sorry to add insult to injury, but i had a celica gen 6 gt befor ma vr6, i had a jap style 4 inch angled exit cat back with a bolt in bolt out cat.. they didnt use gaskets so it was blowing, the silencer in the centre section is rusted as the titanic after only 5 months, the tail pipe on the can has turned a crapy gold ish colour and i wanted a chrome tip. the noise was a lot more of a performance roar than the previous back box i had on it. the only reason i used them was because for my celica they didnt make off the shelve kits, and this was the closest place .(mine was the ST - uk spec
