Wussup everybody I'm about to order my WS Y-pipe and I know that the diameter is 2.5" but I don't quite remember the diameter of the stock exhaust piping......so to get to the point the question I'm trying to ask is, will the y-pipe go in with out me having to make any modifications to the rest of the exhaust system? will it fit on the factory cat?

 

The stock exhaust is 2".I had no problem putting mine on just a bracket to grind.But mine is a VE.But it was very easy to put on and lots of room for it.

 

Dan 93 SE here, I posted a reply to your question but entered it under a new thread by mistake. See WSP y-pipe under the 3rd Gen. Thanks Dan WSP
