ZL1 kooks headers stock npp 

Not bad ! The Borla Atak would knock houses down ! That's what I have with stock manifolds.

Man unless you have the spare money just laying around I couldn't see justifying aftermarket mufflers! This thing sounds perfect with just catless headers.

Damwwwwwww 💯perfect I can’t imagine with corsa extreme catback

Loud boom nice idling🚀💥

Hey I was looking to order these for my zl1. Did u only order the headers and off road connection pipes? Or did u add on 02 extensions, gaskets, msd wires etc as well?

Had a 010 camaro ss 20000 miles put kooks stainless headers perfornance cats x pipe stock 😢mufflers used ARP header studs with 12 point nuts always popped when let up annoying deleted fuel mnt always had code delete code again needed a tune fitment was perfect

Sounds like mine when it starts up. I have street engineering headers with no cats but it has a stress fracture and havent put the kooks on yet. Sounds good tho. What did u out down with this current setup?

The cars farting lol

Sounds incredible. Have you had any issues with the cats?

Where did you get the 1le splitters and spoiler? Sounds sick

Was this cold start in Sport mode, or did you remove the NPP fuse? I'm trying to compare how much louder this car will be in touring mode with the stock NPP.

show us in each mode such as silent mode sport and track

Are those 2”?

Do you need to tune when you add headers?

Stock exhaust?

Any rubbing issues on the steering shaft and any issues with your wire harness rubbing and potentially melting on the passenger side?

Why does it rattle on the start up like that

God dammit¡¡¡!!!

Eh, sounds too raspy for me unfortunately :(

is everything stock ? the only you thing u did was the headers right? nothing else..?
