X-Pipe what does it really do????
Actually, they did a test on 5.0 Mustang and the H made more power and torque everywhere. I'll try to find the article. The difference is negligible. You won't feel it on the butt-meter and you won't see an advantage at the track all other things being equal. Pick on sound alone. I like the deeper note!
