Cutting Open Corsa's NPP Valved Muffler | WHAT'S INSIDE? 

What’s up to a fellow 6th gen Camaro LETS GOOOO🙌🏼🙌🏼🙌🏼🙌🏼

What up bro! 💪💪🏁

@@ZtZoomin not much man putting in some zl1 brake lights this weekend

Nice, did you get the phastek ones? Someone was saying they no longer make the GM ZL1 tail lights. I hear good things about phastek’s tho

@@ZtZoomin oooo you will have to see I’ll be filming over the weekend 😉

I knew what it does but never knew what it was called. Thanks!

@@ZtZoomin yeah its a really cool design they have... Thanks for Chopin it up for us to see how it works 👌👍👍💯

Glad you enjoyed the video. Thanks for rockin’ with the channel 🤘💯🏁

Not sure that serves a frequency-cancelling function (Helmholtz). Normally, that's a chamber that induces out-of-phase sound at a 90-deg angle to the exhaust. This appears to quiet by a combination of pressurization and sound packing. Sending gases thru the muffler body (and forcing it thru multiple smaller holes) MAY increase back pressure (one way to quiet exhaust) while also routing gases through a mini resonator. NOTE: Gases don't run to the valve, bounce-back and reroute into the muffler. Gases would pressurized the "stub" beyond the muffler inlet when the valve is closed -- thereby forcing gases to take the path into the muffler. Because that's not a smooth entry (turn) into the main body of the muffler, there would be some losses there too. Of course, that's typical of any valved muffler on the quiet leg.

👀💯💪

they've always have sport and extreme. this was their new (at the time) valved exhaust, which is neither.

BOOMIN’ 💪💯🏁

Got you bro! 💪💪💯

Yes sir 💯

It definitely has corsa’s unique sound. All Corsa extreme exhaust’s are basically straight through

@@ZtZoomin you had non NPP CORSA extreme axlebaxk with your current catback system, right? Comparing corsa extreme catback w/ none npp axle back Vs Corsa extreme catback w/ NPP axleback (valve open) We're you able to tell the difference?? Any tone changes???

No I did not. Npp corsa & non npp corsa sound the same

@@ZtZoomin that’s awesome to hear because all over the forums you can’t find a clean answer for that question! I’m glad I watched through this whole video haha

exactly .. the corsa unique sound is about that X pipe .. nothing else

💪💯🏁

I’d love to if you donate one

@@ZtZoomin I actually have two from an old m6. I can sell it to you for a great price 😂

Lmao

That sucks, I’ve had nothing but good experiences. Every issue I did have they took care of immediately. Try reaching out again, might get someone different on the phone. In my experience they always stand by their product

@@ZtZoomin bro I placed two orders with them. 1 for an intake for my Camaro and a second a week later for their cat back exhaust. After 5 weeks they shipped me the wrong item number intake. I called them they said ok we will send u a second one return the first. They sent me a second one wrong again. Meanwhile they refused to ship my second order because of their mistakes with the first one. I waited 7 weeks spent over 2k with them and had to file PayPal claims and won both claims to get my money back. I returned both intakes and went with borla and CAI. I dealt with Corsa on the phone like 10 times dude. They're spiteful and unethical. They screw up and take it out on the customer.

@@runawayslave1087 damn man that’s all bad. Thanks for sharing your story. Glad you were able to get something figured out 💯
