Too Restrictive?
I have got the motor in the truck and have a question about exhaust. I have a head pipe from an EFT truck cut off right after the H. I was thinking about using that and running 2 1/4" the rest of the way back. Do you think that head pipe is to restrictive? Heres my setup and thanks for the info.
