what's up with stock exhaust?
it seems like the stock exhaust was designed very poorly:don't know:, it's kind a good cause you can make a lot more power with an aftermarket one, but still got me confused. The header is somewhat 4-2-1 design but it connects cylinder 1 and 2, and 3 and 4 stead of 1-4 and 2-3, primary tubes seems little bit on the big side and the rest of the exhaust is little bit over sized, the under tail tubing were designed to support 210ish hp or so.
My question is to those with aftermarket exhaust, what size primarys on the header, and what type? ( 4-1 or 4-2-1), this big bore and short stroke engine almost asking for a 4-1 header, and I am sure 4-2-1 design is there to get little bit of bottom end torque back in it. And what size is the rest of the exhaust including the rear undertail section.
