only way any pipe fits the sr is with some strange bens or a horible matting angle at the barrel.. hence the better pipes dont fit. as for stockers fuck knows, i know the sr pipes have the lil notches so you can mount them in one peice.. mabey it does fit but you have to put it on sectionally for clearance as when i tryd it was in one peice. just couldent get it into place where as the sr downpipe on the exhaust it all slid into place because of the notches and the ability to get it in place then roastate onto the studs.. so in short it probably does fit if you take the lot apart but dont quote me on it, it didnt go on for me in one peice thats for sure
