Looking for new exhaust
So I am looking to get some new Exhaust on the Z51. It has the NPP now but it is just not loud enough for my taste. Should I get a Corsa X pipe and leave the NPP's? Do I get an Xpipe and take the mufflers off? Corsa X pipe with Corsa Extreme? Long tubes with no cats through NPP's? It is tough to figure out by just listening to You Tube videos. Give me some feedback.

The x-pipe is easy and cheap, thus I would start there. I found it was perfect for me. However if its not loud enough then you can move onto swapping other parts of the system.
Personally I would not do anything that alters how the NPP functions. I put an aftermarket exhaust (cat back + muffler) in my previous car and there were times I wish I hadn't touched it. On long road trips loud can become pretty annoying.

Get an xpipe first, I was fortunate enough to get the Borla catless xpipe before they stopped selling them, sounded better but still not what I wanted so I went with Magnaflow comp exhaust and yep !!! Now it sounds like a Corvette should !!

yup...xpipe first and see where it gets you.
I have the car and with the xpipe my wife says it shakes the house in the am....granted i think i could always go louder but theres a fine balance between loud and obnoxious. Also, the good thing about the xpipe is that at normal throttle its not a whole lot different but when you get on it, it really opens up. I also added a vararam intake and love the combination of the "suck" sound with the xpipe...

I started off with an x pipe and it wasn't enough after a couple months.
I feel like everyone eventually ends up upgrading their axle back portion as well.
I would suggest buying a Corsa midpipe as all midpipes have been discontinued and theres only a limited quantity available.
We can also get you pricing on axle backs.
Contact me for pricing on the Corsa midpipe!

I think the general consensus is to start with the X-pipe and go from there. I'm pretty sure when the time comes, that is what I will do.

I had the NPP on my 2014 Z51 but I soon swapped it for Corsa Sport and Corsa X-pipe.... I love it.... no need for NPP !!! But they might be getting hard to find! Good luck with what ever you come up with! CJ

But this stuff is super lite can pick it all up with your small finger. Love the sound in TRACK mode. If you dont want to look at LT headers do the no cats with the Extreme set up on the mufflers. This will be your best for loud other than no mufflers at all & that is just to much if you do and road trips at all... Robert

Hey fellas. I just got a 2019 M7 ZO6 in October. I really want to put an x pipe on that deletes the secondary cats, but am not sure which one to get since the Borla is no longer available. From my research, it seems that was the best one.
Any opinions on which one out there is just as good, if not better?
Would cutting out the secondary cats and replacing with 2.75" pipe work just as well?

Had AWE x-pipe installed last week on factory car with NPP, as others have said it sounds great when you romp on it but only slightly deeper and louder at idle. Cold starts in the morning can be loud though, and i leave very early (sorry neighbors).
AWE does make a nice piece so get it while you can
