I have a 4'' single hideaway mufflex system with a spintech race series muffler on order. I have hooker comp shortys. What is an appropriate y-pipe to use with this setup? I cant seem to find anything. I haven't seen anything larger than 3'' exit y-pipe. I would like something closer to 4'' maybe 3.5''?

Does anybody have this setup? I would really appreciate some input.

Thanks.

Currently I have true duals but soon I will be dropping the nose down ~ 2inches and the rear ~ 1.5''. I am at max ground clearance with my setup and am scraping hard on my driveway, and highway bumps. so I'm going back to single pipe
