Bo and I put the LT's on the truck this morning in about an hour. Turns out the Pacesetter Y pipe doesn't play nice with the 6l80e, so I had to have one made. I'm still on the fence about which muffler I'm going with... 3.5" Spintech Super Pro Street or 3.5" Moroso Spiral Flow. Anyway, until I make up my mind, I'll be running this setup.
Pacesetters -> catless 3" Y pipe -> 3.5" exhaust pipe -> stock muffler -> single out the back
