[ihop]

Need some advice on a exhaust system for my truck. I want to put a Flowmaster 70 series muffler 3 inch inlet and dual 2.5 inch outlets. What y pipe should I use, i am eliminating the cats. Currently has dual mufflers and pipes but is way to loud. Cant hear myself think! Your suggestions would be greatly appreciated.

I don't know of a ready-made Y-pipe to fit the 454. Small-blocks can use the JBA 2831SY
