I would put some Pro Street Spin Tech's on it.
Straight pipe sounds like shit to me. Way too much resonating!!!Don't be afraid of the bottle!!! Be afraid of your tune!!!

Well with the straight pipes you gain some back pressure and exhaust velocity due to the pipe. To see a real gain with the cutouts open other than the trick in your mind due to the loudness it must be tuned for power when the cutout's are opened. Which will also hurt drivability when closed and running mufflers.
We even put mufflers on ALL the race cars now including 7 second mountain motor door cars.
