So easy a Caveman could do it! Got that from Brandon at Maryland speed !The real purpose is talk about Header sizes. After taking off the stock exhaust and looking at the HUGH
ports of the Ls-3 and stock gasket to the motor. I about crapped
Thinking 1 3/4 is too small! So I mic'd the ports vs the Kooks 1 3/4
and indeed it is a 1/16 bigger! Looks like no restriction to me.
I was half hot till I measured them!
Good info. Have any pictures/sound clips? I may have to drive up to hear it in person. Well that and inspect the JSB color. Good luck with the install.
