Re: ISO Flowtech Y-pipe
If its for the el cheapo shorty headers, good luck. Im pretty sure there isnt one made. I had to hack up some ypipe that summit said fit just to get it to fit. It still hangs super low and bottoms out.

Re: ISO Flowtech Y-pipe
I just got one from summit it was two and a half inches and bolted right up to my summit headers but the y pipe was made by flow tech. I don't recall the part number but I know summit has them.
