Two things affecting the recordings going live tomorrow.

I'm in South Carolina so if it's still raining I won't be able to do recordings
If the dealership messes up the car swap, it will take an extra day to get it

I'll post something tomorrow either way.

O.k. I've got a quick question. Did the "standard exhaust" Camaro have the fuse #8?? I'm asking because mine does/did. Though my Camaro didn't come with the NPP Dual Mode exhaust. However, I decided to pull everything apart to see if mine had the fuse. Sure as hell did, so I pulled it. I've noticed a very minimal change to my exhaust. As I'm not running my stock exhaust anymore, I've got Flowmaster Series 10's in place. I can say, that I did notice a smoother acceleration, though it could all be in my head.

Just wondering and maybe those whom have more experience with the NPP can elaborate. I'm not just wondering if there is always a "flapper valve" located somewhere else within the exhaust (i.e. like a motorcycle's exhaust, I had two bikes that had the flapper valve in the midpipe).

I don't see any way the fuse pull for NPP can have any affect whatsoever on a non-NPP exhaust Camaro. Are you sure the number 8 fuse on a regular Camaro isn't for something else? If not, I'm guessing its just not used.

I pulled mine not knowing if it was NPP equipped but it had the fuse. I have Magnaflow Glasspacks and could tell no difference at idle or WOT

...except my MPG went down to the lowest since I bought the car

when I took the fuse box cap/cover off, it listed fuse #8 as "exhaust flap" so I don't believe it's used for something else.

I took some videos today but they were crappy because I was driving home from the dealer and left the new sunroof open (still getting used to that). I will take good ones tomorrow with and without the fuse so people can get an idea.

Questions:
Does the standard V6 exhaust have a fuse #8 and does it do anything?
-No, The NPP has flaps in the tips (you can actually see them) and the fuse closes them at certain RMP's. Pulling any fuse related to flaps that are in standard exhaust will have no effect, I can't see why GM would put a fuse in there for no reason if it wasn't NPP but it may be for something else. I no longer have Megan so I can't check sorry.

Is it louder?
-Hell yes, when I drove away I couldn't believe the noise it made and when I pulled the fuse it got soooo much better. Not to mention the quad tips looks a lot better IMO. My only issue is I don't know which way to park it at the house anymore because I can't decide if the front or the back looks better... Good problem to have.

Is it worth the MSRP sale price of $900
-I think so, I'm very happy with the noise. If I bought another one I would opt for the NPP. I would absolutely suggest this upgrade. My next goal is to get it to a car show and do a side by side with a V6 rocking MRT 2.0's
