So what I'm gathering is AWE Touring is the best for Axle-Back WITH the NPP Valves??? Or is there another system better that utilizes the NPP still??. I would like a system that I can still use the Valves with.

I run Corsa Extreme NPP on my ZL1 non 1LE

Quite a few choices that still retain the NPP valves, none sound like AWE.

Would you mind listing some that retain the valves here please?(with or without links) Either I'm not searching correctly or I'm looking for the wrong thing. I tried the Flowmaster American Thunder Axle- Back(had tried to order it last September) their ship date keeps getting pushed back(currently 5/31/2023)so I called them to find out what's going on and they told me they're waiting for a part from China in order to finish making the kits.(WHAAT!!!??)
Then I contacted Borla about the Type S axle back with black tips and they emailed me back and said that particular system is only available as a Cat-Back.

Stainless Works has a cat back system that keeps the NPP valves and a axle back too.

I run Stainless Works headers, Gesi2 UHO HP Cats, Corsa X pipe to Borla Atak NPPs axle backs and its loud with zero drone.

I did quite a bit of research before I bought the AWE and I believe the only two are the Corsa and Borla that will retain the axel back. There might be a smaller company I’m not aware of. So now that I’ve had the AWE for a week I don’t miss the NPP exhaust one bit. Yes the cold starts are much louder but if you’re just cruising the AWE isn’t much louder than stock. It’s just higher up in the rpm’s where it really screams. And the tips are a work of art.

Thank you for your response! I've been emailing a rep at AWE(just clarifying questions mainly). Leaning towards getting the AWE Touring axle back with Black Diamond tips. My only hang up currently is losing the NPP valves in fear that I'd miss them so I appreciate your feedback about not missing the valves, that helps bring me back from off the ledge a bit!

AWE Resonated Touring catback here. No valves needed.

And just FYI they are sending chrome tips now because the black are currently back ordered for who knows how long. You have the option once you get them to receive a credit or have the black ones sent out once they are available and keep the chrome ones as well. I chose to get the black ones. And it took me about an hour on ramps to install. Super easy.

Oh, nice! Thank you for the heads up on the tips and time on install! Appreciate it!

I like the Corsa NPP axle back.

Looks and sounds incredible.
