i was lucky enough to purchase a complete NPP system from a local person for 70 bucks. I don't think they knew how much these go for since I've seen these for 400 in some places. I spoke to a local shop to get the axle backs fitted on the G8 and i was quoted 200 bucks to make them fit properly. Considering the price, do you guys think its worth it? don't know how bad the drone would be with the flaps open and how good it will sound once on the car. I have a 2013 1LE with LT headers and high flow cats and it sounds great but does have drone at highway speeds. My G8 also has LT headers and these are catless, so they might be a bit louder.

at this point, idk if i should sell the NPP and get a solo axle backs, but they are pricey.

Anyway, opinions are welcomed.
