They are Dynomax Super Turbo. I'm running Doug's headers into 2.5" to the mufflers, then 2.25" tailpipes. I had an "H" pipe before I did the swap. I plan to add it back at some point but for now they are separate. The cam is 216 duration @.50 and 517 lift on a 110. Not too radical.
I had Flowmaster Series 40's but they were much too loud for me, lol.
