I have the dual mode exhaust from GM, I did a muffler delete on it and everybody freaked out that I cut the NPP. I was told that they can be put (welded) back on and be good as new. I also plan on doing a cat delete, can you guys tell me if I screwed up the NPP or am I good.

why would you pay for a option, then butcher it up? should have just took the standard exhaust and cut it..just my thought

NPP with no mufflers is much louder than stock with no mufflers. Looks nice with quad tips too.

I made sure to get NPP price deducted from my agreed price though, its one of three options on my car and it's the most expensive. I went in during the open house deal in March, got the dealer to give me more discounts, showed them the $1,000 private offer, and once they know your serious about it, throw a curveball and say I'll only buy if you deduct this. This case being the NPP. If they don't, walk out, guarantee you'll receive a phone call in the next day or so.

Free meaning they deduct the price of the option from the price of the car including all deals. This case being the NPP.

Dude, you didn't get your NPP for free! The dealer has a bottom line price they need to get and if the car didn't have the option then that figure would have been lower by whatever their cost for NPP is.

Yes I know how the dealers pricing works, I got my car at a price I am happy with and then lowered it even more. I got a $36k car for $29k OTD. It did take a couple weeks because the dealer said no way, however one day I got a call and salesman said come on in.

the NPP is one of the best exhaust money can buy. you could have sold it for $700+ got there regular exhaust. but ya just have it welded back together and almost good as new. All most because it will be a few mm shorter because of the metal lost in the cut.

Well, you definitely screwed up the NPP. NPP consists of a pair of dual mode mufflers and you removed them. You don't have NPP anymore.
How do you plan on passing California emissions after you delete the cats?
You will also have to get a tune to turn the CEL off after you delete the cats, which will void your powertrain warranty.
But, hey, its your car.
You can do what you want to it.

I'm gonna weld the mufflers back on and sell the NPP. My warranty is going to go in a couple weeks with headers anyway, I might keep the NPP or sell it and buy another system.
