I noticed that alot of people are changing their cast-iron dump-pipes for 3" constant radius ones. I plan on doing this as well but I have a question.
Has anyone built or bought a 4-to-1 equal length runners, tubular exhaust manifold for their 1KZ-TE?
I just find it more wise to start at the motor and work my way back. That way I wouldn´t have to change my down-pipe and exhaust when I finally make the manifold.
Something similar to these.
