2014 ZL1 Convertible exhaust recommendations?
I am new to this forum and the ZL!- I just bought a stock 2014 ZL1 convertible. I am adding the Jannetty Racing 75rwp kit and would like to get a little more sound out of this car. Any recommendations for exhaust? Would a cat back or axle back be more appropriate? Would I see any gains from the Cat back with no mods besides the JR 75kit? It seems most cat back kits are for coupes...

Don’t waste your money on a cat back. The factory NNP sounds great with headers no cats and a x pipe. Plus you will have a hard time fitting any 3” exhaust with the x bracing.

All zl1’s have them. Just look at you mufflers, you should see the actuator.

I feel like a Corsa setup would fit as an axle back... or a Bullet Performance.. I'm in the same boat.. I have a catback but it's got too much drone at highway speeds it drives me crazy right now...
