Smile It can be done

I replaced my 2 1/2" x 24" Lone Star sidepipes with the louvers turned backward so as to not pick up air flowing pass them, for Classic 3" x 28" with the louvers turned to pick up air flow. I also moved (rotated) the tips up 15 degrees so the exhaust would not "hit" the ground beside the car. It now blows more of across the pavement.

I gained hp on the dyno and it's a lot quieter. I can talk to my passenger at 70 mph with easy. I could not do that before.
I still have that deep rumble that a Cobra should have. And when I go full throttle, you can hear me.
I have the best of all worlds.
