He friends. My bird is nearing completion and I'm looking for some exhaust help. What I want to do is have a setup similar to _95badbird's. His comes off the longtubes into about a foot of pipe then into mufflers and a dump just after the front seats. I am wondering if an H pipe or X pipe is necessary? I have read around and the SBF guys like em alot. Do I need one for my setup? Also What size tubing do you recommend for a 302 with stock headers. I want to have a little room for some power adders. Help greatly appreciated.
