JOHN-DYNOSTAR Posted April 15, 2021 Share Posted April 15, 2021 the stock gen2 14's are as rich as that on full throttle and I think it is to cool the charge for the cats and back pressure to stop detonation within the engine. (there are 4 cats in the later gen 2 kwakkers) personally once the exhausts are off and it breathes better it will equate to the gen 2 but that is a big tail off and I suspect the secondary butterflies will also close at the top end to restrict the flow into the engine . it is after all emissions based and the exhaust will only flow so much to get it to perform correctly the silencers would need to be twice the size. not practical really Quote Link to comment Share on other sites More sharing options...
