exhaust mod idea
if freeflow exhaust gives more performance, how about a super restrictive exhaust, maybe with one of those tractor flaps with a small spring to hold it close tighter. less crankcase venting wil work like an egr.
Then you need some 1/2 or 3/4 inch emt tubing and from the back run it to the intake for the ultimate EGR mod.
this way, the extra pressure on the exhaust forces more exhaust gas into the intake, kinda like the exhaust fed back into the intake but the springloaded flap will allow some exhaust to escape and allow some fresh air to be sucked in
Seriously though, what would increasing the backpressure do?
