I just checked out the Spintech site. I've heard good things about them, but I can't find a dual in/single out muffler. I really don't want to put a y-pipe on my truck.

My idea was this, run (2) 14" Dynomax Bullet mufflers (one on each pipe from the cats-back) so I maintain the true dual setup. I was going to dump the tips underneath the truck, probably right underneath the cab. I know it will be loud, but less exhaust pipe = more efficiency.

I can't think of a more efficient setup than maintaining the dual exhaust and reducing the length of the system, while using a high flow muffler.
