Did you contact Dinan to see if they could help? They usually respond the same day.

The Dinan dealer that installed it said that the ZHP didn't need a different exhaust system. I'll probably mention somethinmg to Dinan at Bimmerfest East this year but the 3.0 doesn't really respond well to anything short of forced induction...When I dyno'd the car last summer it pulled a dissapointing 191HP at the rear wheels..
But I digress this is the e53 forum...
