Does anyone know of any articles or personal experience that show dyno numbers for a prochamber, a x pipe and a h pipe? I know alot of mid pipe selection is based on sound preference, but I was just wondering.
Mustang Enthusiast magazine did a story on several diff mid-pipes a couple months ago. In the end, they were all within a couple HP of each other, including the single H pipe they tested. Go for the sound you want - the power difference is minimal.
