Has anyone done some back to back track testing with the 3 1/2" X-pipe system that dumps in front of the rearend. Compared to open headers ? I thought about it today but got lazy. Just wondered if it would have been worth it. But it's so fun being in the "STEALTH MODE":Brow:
I think 'HOT ROD' magazine did a test with an Olds. -And it actually went a bit faster than with open headers.... -Yup. -faster..
