Ok guys heres one for ya. I was doing some work on my back bumper of the vette this morning with the car running and I noticed my passenger side exhaust blows a hell of alot harder than my drivers side Ive got straight pipes from the manifolds to the back bumper both through cats no crossover pipes at all. Is this normal? this was just at idle I havent tried it at higher rpm's. Is this an indicator of future engine problems or something as simple as a clogged cat

Sorry if this is in the wrong forum..but I was thinking along the lines of valves not opening all the way? any ideas? or dont worry It runs fine I drive it all the time Thanks as always
