"very respected Superformance builder/dealer said I was just wasting money"
DANG!!! Wish I had talked to that very respected dealer! Could have saved a bunch.... Of course on the other hand, I be short 50hp, the rusted out muflers would be banging around inside the pipes and the car would look like hell with the crap ceramic coating, but what the heck.. It would at least get the endorcement of a "very respected dealer".
