Hi all,
Ive bought some headers from iPunkz (https://www.ipunkzexhaustsystem.com/?pr ... ader-carry)
I did a CFM calculation (https://m.roadkillcustoms.com/determine ... bing-size/), and estimate about 60hp output
60x2.2 = 132 CFM
Im going to be fabricating the rest of the exhaust. Would 1.25" diameter be about right? Planning to put a mid muffler or resonator
