[QUOTE="NSEric, post: 7119536, member: 157288"] Imo you wont gain any more useable revs with the exhaust at 90 degrees. It will piss rev crazy high but drop down to the same or lower rpm while cutting than your getting now. The other ports and carb size limit you to 15-16000rpm so there's no point in crazy high exhaust ports to try to get more rpm. If you want less compression, don't cut as much off the base and squish band. [/QUOTE]
