I pulled the exhaust module fuse out but there was no difference in the sound. I figured that meant that I must not have baffles that open/close, but I thought I would check on here to see if there is something else I was supposed to do that I missed.

Thanks

If you see butterfly valves in your exhaust outlets, then yes.
Sticking?

Did you walk around to the back and look? You will see the valves.

If your car has these valves and the actuator on the mufflers ... you have the NPP:

See how the valve is wide open when the engine is not running (the valves are on the 2 inside pipes).

Great pic, Turbo.

Thanks for the explanations and pics. I just took a look and I don't have the baffles, so no NPP for me. I wonder why they still have an exhaust module fuse with that being the case? Oh well. Thanks again!

Time to spend some money on an awesome sounding aftermarket exhaust system.

And if I remember correctly, there is a $1,195 charge for the NPP on all GS Models...

Some Corsas would sound sweet

Ouch, I think I would rather go aftermarket with the price of stock being that much.

The last time I checked on the Aftermarket Exhaust that I have used in the past, I think the price was like $1,600. All of a sudden they were charging $400 more for Automatics than Manuals. Thats why I went with the NPP...

That's a great deal compared to installing the comparable B&B Fusions

I could not ask for anymore sound than what comes from my NPP'S. Of course the fuse is pulled

Go with the Corsa's if you do change/

The "Corvette Tax" has gone stupid on aftermarket exhausts the past few years.

Don-Vette

I got the NPP on mine so I didnt have to mess with any after market exhaust and it's much cheaper too!!!

wolfdogs

no offense to anyone.. but i just don't thing an exhaust system should have moving parts...LOL...im from the old school... then yall pull the fuse and its just waste of stuff sitting on there.. LOL.








Corsa Extremes here... gorgeous tips, gorgeous sound, all the time

Its factory and its good!

I agree to some extent. I wish there was a way to turn off NPP so it doesn't surprise me going up the highway ramp at half throttle. I do like to uncork when it's appropriate but I want to control it.
