Will 2014 NPP work on 2010?

I have 2010 SS and have the chance to buy a npp catback from a 2014 and just wanted to make sure it will fit. Also if I donít hook the vacuum lines up the muffler will stay in loud mode right?

The NPP will fit, you will need the 2013 rear lower body panel for the dual tips. The mufflers are always in open mode until you put vacuum to them so the answer is yes, it will be in loud mode. Dont waste your time hooking up the vacuum lines, you will end up taking them off, LOL

Appreciate it! Yeah I won’t be hooking up the vacuum lines then haha. I have borla s type catback with LTs and HFCs and I wouldn’t mind it being a tad louder

Not sure how much louder it will be but the NPP is pretty much a drone free proven exhaust system! Sounds good too.

My 1le had the fuse pulled when I bought it. Drove it from KS to mid Mo and it had zero drone. You'll like it no question.

Zz430 is exactly right. Also they do make kits to make the valves active, but, I agree, no need. It sounds great with the valves open.
When you take the rear diffuser off make sure you put tape on the painted surfaces of the bumper to protect it fro. Your pry tool (plastic trim pry tool is best).

I just took my time with a Dremel and trimmed my factory diffuser. Looks good and saved me $100. Pretty simple.

I didn’t trim the hole straight down, I left a piece connected under the tips so I didn’t have to build a brace to stop it from flopping around.
