Looking for suggestions on effective mods for 2019 ZL1 - Page 2

Is there a good catback system that lets you keep the NPP functionality ?

Keeping NPP is a requirement for me since I have a 3y/o daughter.

Borla is the only one, I had heard Corsa is working on one, but have not seen it. I prefer the sound and technology of the Corsa

Cool thanks. I like Corsa too, maybe I'll wait and see if they come out with the NPP version.

Borla Atak sounds pretty darn good though.

after settling in on the sound I want and the optional change we have with the NPP, I ended up going with Flowmaster 817746 with midpipes , (scavenger) #81083. I am not sure who really cares but since I got so many tips I thought to just share one man's choice. It was handled by Juiced Motorsports. Anyone else work with them? Seem to be reasonable pricing. Only issue is right now I am waiting for the 817746 pkg to show. It wasn't sent together as a full shipment. Maybe this is normal but thought to ask. I am not in any way complaining, at least yet, but curious. His prices are great and he has options available on many other systems.
Let me know any thoughts out there.

I've worked with Juiced and would do so again. Quick responses and fast shipping and when a part was accidentally forgotten, Jason overnighted it for me. They're a great vendor.

I would go with Borla in that case. They're nice setups. I have the Corsa Xtreme+ cat-back and love it, but it's rowdy on cold start. Even if you have the valves, I don't know if it helps cold starts much/at all...Can't remember if it starts with them open no matter what or not.

That is the sense I get. I just spoke with him and they are going through the checks where the package might have gone. All good. But it is always good to get opinions.

Second that regarding Juiced. I originally ordered my exhaust from Maryland Speed and most know how that turned out. When I filed a chargeback against Maryland Speed, I went to Juiced, they just about matched Maryland Speeds price and I got it quick.

I would use them again.

Question, in the second vid, is the car echoing in your neighbourhood? Lol
It sounds loud but killer

I hammered it, and the Outlaw is just raw...but killer!
And then, you can pop it into Stealth mode...and it still sounds good, but quiet!

Holy cow that’s loud!

...and sounds great too

It seems that appearance is important to you. With a black car kept long term, keeping the paint looking good will be challenging.

So I’d recommend investing in a good new car paint correction and paint protection film (top shelf self-healing type like Suntek ultra or Xpel ultimate). Do the whole car. Then add a durable hydrophobic coating (gtechniq EXO or feynlab topcoat) on top of the ppf, can be done DIY. Do this first before any other work and it will save your paint from accidental shop damage.

Don’t waste money on ceramic coatings over the PPF (it will water spot) but do coat the wheels.

Also put aside $150 to swap out the factory pads with powerstop z26 pads to end the brake dust blues.

The ZL1 is an absolute baddass in black, and Mosaic Black Metallic is one of my fav paint colors of all time. Enjoy

Absolutely no drone on mine...I have headers and no cats...I drive it all the time in Track mode, as soon at it hits 1600 rpm where it wants to drone the NPP sytem regulates the system and it quiets down.
I pulled the fuse a couple times and that baby will rattle your brains.
