Kooks axle back sound
I already have Kooks long tubes along with the matching x pipe. Does any one have the kooks axle backs also. How does it sound? Any drone?

Drone? lol!!! They drone OUTSIDE the car. I'm not kidding! The drone with FULL Kooks is UNBELIEVABLE! The sound is amazing, but it's pretty much unbearable in the car.

I have headers race cats, no resonator then straight through Magnaflow mufflers. Drone loosened teeth. I added a 18 inch long 3 inch pipe X pipe and it totally got rid n of the drone and some of the excessive loudness, it is perfect now.

How are your thoughts on stock GXP mufflers?

My favorite direct bolt on axleback. I like the sound of Corsa better, but they don't offer a simple direct bolt on axleback, so the GXP mufflers were my best option.

I'm guessing you can't buy GXP mufflers from gm anymore.

Might be available still. They were stupid expensive from GM. Even the GT mufflers are/were stupid expensive.
