Installing a downley long tube header on sunday... getting it from a friend who will do all the welding and yada yada that needs to be installed.

He told me to get some exhaust tubing for something, cant remember what.

anyways. whats the stock size? 2.5" or 2.25"

i believe stock 1 7/8 , you will be better off wiyh 2.25 with the header

Stock exhaust tubing size 1.75". I have LCE header w/ 2.25" out. If in installed w/ air intake modification the torque and power gains are awesome. Used to have 2.5" on my old 87 22re w/ same header and intake... It would pop like a NASCAR when I left of the gas due to the backpressure. IMO go with 2.25" and you will be stoked.
