Megan resonated test pipes
Test pipes should not cause the engine to "torque" anymore than normal. There actually should actually be more clearance than the stock cats had. Something definetly sounds wrong. I'd get it up on a lift or atleast some jacks and have someone rev it while you're underneath...see if you can see anything happening or atleast pinpoint where the noise is coming from.
