I was wondering if anyone knew the size of the primary diameter of the stock headers and also of the long tube headers that are on the market, Evolve, Agency Power, etc.

65mm is the piping that mates to section 1

Thanks. Could you also measure length of one tube and also collector length and diameter? I assume the port size will be the same between stock and aftermarket.

65mm

Thanks. That would put the stock collector diameter at 2.5"
