I was wondering if it is possible to retrofit the NPP exhaust on Vettes that did not have the NPP option? Is it just the exhaust or are there other components involved?

Thanks

Retro fitting from non NPP with OEM parts may be a big pain in the rear.

I decided to go this route. I ordered my system through LMP Performance. They had the best price and free shipping.

I bought the NPP exhaust from forum member who wanted even louder. Not possible to retrofit controls without major expense. Mine is wide open all the time. However I can quiet mine down with 1 1/2 inch angle installed in opening as described in forum thread.
