Stock NPP catback is good up to how many HP?
How much HP can you add before the stock NPP catback becomes an issue?
I like the NPP.

Not even close to what Redlineviper & Sakudog are putting down but I have no desire to change out my NPP.

Stock NPP is awesome.
The exhaust will be the least of your worries if you start adding power. The ZL seems to be the most robust Camaro ever built. Mod the your hearts content.

NPP has to be one of the best OEM exhausts made. Its such an innovation to the Camaro IMO; You can accomplish great things with just leaving it in place.
