Really cool like the sound easy to install. And easy to operate.

These cutouts are amazing. One thing to look at is that these will hang down a bit and lower your over all clearance.

After installation, I knew this was the exhaust system for me; I’m able to keep it closed for a subtle driving experience but can always open it up and have incredible sound.

I was worried about them rattling, or the housing getting chewed over time etc. but MAN, 4 months and no problem. I went with these over other brands because my fathers buddy has them on his chevelle and they’ve been perfect for 4 years straight! So far no complaints, make sure you weld them, don’t use the brackets, those are prone to leak.
