Corsa NPP
Hey y'all,
Hope your Monday is going well. Someone once said the Corsa NPP is basically a Corsa Sport while the valves are closed and an Extreme with the valves open. Surprised that it's not quieter than a Sport with the valves shut. Can anyone who owns one chime in?

I’m looking at it. From what I’ve read it’s the best mild to wild system out there. However I’m ok with the stock NPP now. I could use a little more volume wide open given I have HF Cats and that tames the headers a little. It’s salty though.

Good to know. I had a Borla S-Type NPP with catless headers and that girl was LOUD. With the valves shut it was decently quiet, but obviously didn't sound very good. Currently have a Corsa Sport and LOVE it, but there's no way to quiet it down. Would like to go with a Corsa NPP, but if it sounds the same as a Sport with the valves closed, no point in spending the coin.

It's quieter then sport with valves closed. I would say it's more like a "touring". Honestly it's not much if any louder then the stock NPP open with Corsa closed. Open it's much louder but tolerable at idle & part thorttle...WOT it screams.

I have the Corsa NPP and I would confirm its pretty mild to wild. I don't know if its as loud as sport with valves closed or not, but this is what Corsa sent me a while back.
Stock: NPP Closed - 91.3 dB Stock: NPP Open - 94.0 dB Corsa: NPP Closed - 97.5 dB Corsa: NPP Open - 108.4 dB Gate guard at work stopped me this morning to ask about the exhaust and hear some revs, it sounds great.

Thanks for the info, y'all. Anyone know how the noise levels compare to a Borla S-Type?

I believe The Borla sport is going to be in-between the Corsa NPP meaning valves closed "Touring" level, valves open will be more like the "Attack" or "Extreme". You get the mild to wild effect with the Corsa Npp.

Thanks for the info! Will report back if I end up getting one, but looks like they're out of stock basically everywhere.

They have been out of stock since they came out. They are built to order...mine took almost 3.5months to get instead of the 2-3 weeks I was initially quoted.

Bumping an old thread here, but has anyone received theirs recently?
It's been over 4 months since I paid for mine now and I still don't have an eta. |

Have you reached out asking for an ETA? They gave me a 3 month timeline and it came in about 4 weeks.

Cancelled my order thru CSP after like 4 missed Corsa ETAs and 3.5 months and just wasn't worth the 2k anymore to me for an axleback
