What mufflers do I need under my ZL1 vert ?

Johnny Camaro · 02-21-2019, 12:07 PM

Hey guys I know most of you drive a coupe on here but are there any convertible ZL1 owners ones changed that big muffler at the back to give it some more rumbling sound (Yes I already pulled the fuse the first day I had the car) but not anything too loud or with resonance.
I even dislike the view of that OEM big thing hanging there.

Thanks

I've been looking at the AWE axle back system. I would like to hear the system with the mufflers and without? Will do more checking this spring after all the snow is gone!

You will find better answers in the convertible section. Understandably so, there are very few ZL1 convertibles built, and thus very few on the forums. I think all axle backs work fine with the verts. Its the CAT BACKS that have problems with the bracing under the vehicle.

Keep the stock muffler and go with AR headers. Then you can keep it loud when you want and quiet when you want. Been very happy with my headers and top down sound. Wide open throttle will put a smile on your face.

Hmmmm I always like a smile on my face.

You've a sound clip/vid from yours ?
No resonance ?
I do like to have that 3x2 foot stock muffler away tho.

2018 ZL1 Convertible A10. No problem with mine, I have kooks long tube headers, with super flow cats with X Pipe back to factory NPP... Sounds amazing and my neighbors hate me in track mode ...Win
