+1 on the torque. more torque=more fun. i've actually stared at that firewall pad for quite sometime now. i wonder what's stopping me from yanking it. i believe kinky's header was 1.5 on the primaries. i lost all of my torque when i installed it, but in theory, the primary diameter is supposed to be 1.5in for a target torque peak at 4,000rpm (which is what i would want).
cylinder displacement= 30.5cubic in
peak rpm 4,000rpm (this may not be your desired peak)
cross section of primary= 4,000rpm/(88,200x30.5cubic in)
= 1.49
primary length and collector design are just as important. the longer the primary, the more power below the torque peak. opposite goes for shorter primary. but, the collector design, which i don't as much about, is beneficial in keeping lower end power. i think kinky may have omitted this on his design.
none of this will matter unless you can mess with the ecu, but you plan on taking care of that.
