update on d-pipe install

ok, the 3 inch down pipe install was a complete success. but man, it was a real pain in the butt. but i think the new turbo whistle and the throttle response was worth it

thanks everyone for the advice!

I've had mine in about 2 tanks now. Nice changes. With the 6637 & DP the motor has a nice smooth sound at 65/70 mph (2000 - 2300 rpm) and it seems like the throttle response in the mid range is improved. Can't wait 'till I have $$ for a chip!
