I have a 96 cummins 12v with 316k on it its all stock except for a 0 fuel plate and a built tranny and pyrometer. I bought two 6 in. bull haluer stacks but i need the t pipe and am not sure what to do about the pipe goin from the turbo to the t pipe should i just leave it stock or put a 5 in. or something on it. I was just wandering where the best place to get a t pipe from is? thanks.

 

I got mine from kenworth or page brake, when i had my old turbo i went 3 to four to the tee, then four to five to the stacks, now with the new turbo its four to five at the stacks

 

your surely better off to run 4" turbo back... 5" might be too much if you dont have enough power

 

What?

A Cummins doesnt need any backpressure. Go big or go home.

 

Generally with anything thats got a turbo, the less pressure after the turbine the better!

F' it, just pull the downpipe off and let it dump right out of the turbine housing
