- A few (like < 10) horsepower maybe because it's a smoother pipe and no secondary cats
- Louder sound from removing the rear cats
- Increased emissions from removing the rear cats
Without NPP it'll be louder at ALL times, so be sure you want that. If you do not remove the rear cats, there's pretty much no point to this mod in my mind. But it's only a little, maybe 10-20% difference in sound at MOST.

IF THIS WILL BEALL YOU WILL EVER DO TO THE EXHAUST SYSTEM SAVE YOUR MONEY. unless you find one really cheap. If you pull the back cats you will get a check engine light on all the time. Are I did put I also put LT headers on at the same time.

Secondary cats are not monitored by the engine system, you will NOT get a check engine by deleting them.
