Default NPP Options

Hi Folks.. 2015 Z06.

I just did a FBO Build, and I really don't like the sound level. I have catless 2" ARH + an X-Pipe.

It's nice and quite in stealth - But when I open it, it sounds good..but it's not what I expected.

I had catless headers + corsa extreme on my 2018 ZL1, and it sounded insane. The thing I'm looking for though is NPP. I live in an HOA community, and I really dont want to **** off my neigbors when I leave for various meets, cars and coffee, etc..On a sunday morning.Though, They all love my car!

Here's one I've seen so far - it seems priced well. I am wondering what other NPP's people have ran. I see them from Corsa (Past what I want to send)

I think I've seen one from flowmaster - and for some reason I love those. I have a super 40 on my 6.2 silverado -sounds good!

Just wondering what you folks think! Thanks!

Billy Boat Fusion would be my choice. I’m not a fan of the raspy corsa sound. I favor a deeper tone

Borla makes their ATAK with NPP. Crazy loud especially with headers, but can still control the exhaust note like with the factory NPP.

I didnt want to spend over $2000 for a axleback npp replacement of factory so I went with the flowmaster outback I found online on sale so I went with it and i liked how it was mostly all together and not having to use clamps for everything. Overall happy with it.

What don’t you like about the sound when you open it up? You want deeper? Raspier? What?

I have the Corsa long tube headers and double helix x-pipe (all catless) into the stock NPP exhaust and it’s loud when I get into it 1/4 throttle or more. She screams!

So is it the volume or tone you don’t like?

Do you have the Billy Boat Fusion? I've read several times that BB has a deeper tone, and that Corsa is raspier. I would love to hear them in person to compare, but seems like BB is not common, and doubt I'll be able to find anyone local with it.
