Duals for my 01 2500HD, way too quiet, need gas mileage too.
I just bought a 01 Chevy 2500HD, it has duals into the muffeler , single out, I would like duals in and duals out, something equivelent to a two chamber flow master. The only thing I found was a system that I believe was from Gibson(?) it was stainless. Found it on Summit's web site. Thanks for any help guys. DVZZ28

replace the muffler with the 22" Magnaflow dual 2 1/2" in/dual 2 1/2" out....dump it at the axle and it will definitely get your attention when you get on it, at cruising speeds you'll never know it's there
