I know this must have been mentioned here before.
But does anyone have any long term experience with one of these on their cars?
My car has no CATs anyway and I just want the sound effects because they are cool
Understandably bouncing off the Rev limiter for long periods of time isn't good for any engine, I'm more concerned about instant catastrophic engine damage like bent valves? Detonation? Blowing my intake manifold off?
Thanks guys!
