NWWD HelP URGENT! exhaust flow are not the same for right and left side
i have a 03 z33 runs on 95 k kms,
i runs on a exhaust setup with
tomei headers
Sard catalyc
Ypipe titanium R1 amuse
R1 titan catback
i just notice that, when my engine running the left outlet throw more flow of exhaust gas than the right side one, coz before im also using amuse r1 titan, but i recently changed to a newer/less kms amuse R1 titan as well, so just wondering why there is a differences in the flow of right and left side of the exhaust.. please need some explanation from anyone experienced it..
and it also applied when i rev the engine, right side like almost no flow at all however the left side flow very quick..

not sure about sard, but some of the old catalyzers would melt with excessive gas and come apart leaving one or both sides blocked... but they noticed performance problems. Either that or you might have an exhaust leak?

if there is a true descrepancy in flow then the first place i would check is the cats. Cats are junk and tend to fail. Since our cars have 2 cats instead of 1 single inline cat they can fail at different times.

kind of like leaking power, hmm but i dont think so the catalyc had problem as the exhaust are from 6 hole to 2 hole then merge into one in Y pipe and divide into 2 again in the muffler

hmm measuring with both hand near the outlet of the exhaust, before i change my newer amuse R1 titan, the flows seems okay coz on the old muffler the flow are same which mean they flow as same amount of gas, and all my 350z also get same flow,

vaynardx, maybe you should take a pic or video or something of your exhaust. maybe its just me but i dont understand half of what your describing here. If one of your cats are going bad then you will notice a drop in performance and/or a check engine light. If your performance is this good then i wouldnt worry about it. It really isn't uncommon for one side of your exhaust to appear to be flowing more than the other side.
