CAMARO6 - View Single Post - Low Cost NPP modification for more volume

[QUOTE=SkiRideDrive;10298328]Hey there.

I was pondering the least expensive way to get a bit more volume out of the NPP muffler when in full open mode. Some aftermarket companies have solutions in the 1200 dollar range and some folks have replaced the suitcase with aftermarket mufflers, etc.

I'm not sure if there is enough clearance under the car, but was thinking that maybe adding pipe to bypass the muffler for each valve could give a bit more volume for minimal investment. This would also allow the car to remain quiet in stealth mode. I have a super quality MS Paint drawing below with black lines showing where the theoretical bypass pipes would go.

Any thoughts? [quote]

That’s exactly how the Hooker system is designed.
