Is the NPP Dual Mode Exhaust Worth It? - Page 7

bturner2 · 03-19-2017, 08:42 AM

I typically replace my exhaust with either Corsa or Borla within a year of buying my cars. Both of those make you make a choice of sound at that time that can't be reversed without considerable expense.

When I heard NPP the first time I was sold. At $900 it was an upgrade that saved me money in the long run. Being able to change the sound is certainly also a bonus.

This is one of those options that can only be done at the time of purchase like a sunroof and one that I would certainly do again if I was ordering another car tomorrow.

Step 1) general compliments on the overall style and appearance of the car
Step 2) the first "wow, cool!" when they see I got the manual transmission
Step 3) "that's f*king awesome!" when they hear it start up
Call it the icing on the cake or whatever, but the sound just seems to fit the car and provokes a visceral reaction in everyone. Then you can turn it down while cruising to better enjoy the stereo, if that's your pleasure.
I recommend this without hesitation.

I was on the fence also for the same reason ($895 for no measurable performance gain), but overall I am really glad I got it. I think the rear fascia looks much better with the quad tips and painted valence and it sounds awesome. I did not have the opportunity to test a non-NPP exhaust, but my assumption is that it sounds similar to the NPP with the bypass valve closed, which sounds decent but much quieter.

I do wish the upgraded exhaust was 304 stainless steel like it was on my 4th gen camaro since I tend to keep my cars for a long time.

Yes i would recommend it. I need the ability to quiet the car down to keep from disturbing my neighbors early AM. The ability to go from mild to wild is great. Saves on cost of a expensive exhaust system later on.

If you live in an urban area and want to be respectful, then yes. That's why I ordered NPP. That, and the quad-tips.

I have stopped caring about respecting the quiet, I mostly keep the fused pulled.

I have magnetic ride control and NPP and have not figured out how to do any controlling of it. In my 15 vette I could make it work with mode settings etc. Mode in my SS only changes track tour etc.

When you have the opportunity, sit in a garage or a carwash port, then change the modes. You should easily hear the difference between Sport and Tour mode.

This ^

When I had my Mustang I didn't care how loud the exhaust was, the neighbors were a good bit away from the garage so it wasn't bothersome. In my new place, I don't think my neighbors would like hearing my car every morning at 5:45 AM lol

On my 2014 RS convertible the NPP exhaust came with the car and there was no on or off control. The flaps opened above 1800 rpms only but you can purchase a controller that installs easily with the directions provided and is controlled with either with one of two remotes or you can program two of the three remote buttons up at the top by the dome light switch to turn it on (flaps open all the time) or back to normal stock operation where it opens the flaps above 1800 rpms. Even on my V6 the exhaust sounds great. Buy it.
