Kegs, I am currently looking into this for my EF 6...I went to an exhaust shop on the weekend, and was quoted 160 to have one fabricated out of 3 inch mandrel bends in mild steel.
I then want to have it hpc coated which i believe is $30 per foot.
If yours is an EF, it is most beneficial, the EL intake is considerably free'r flowing than the EF's..
I have been told 3 inch is adequate, and 4 inch may even slow the flow of incoming air?
