Anyone dyno front cat delete mod ?
Could only find this one Dyno Shows an 8 hp increase by deleting the front cats. Most Dyno's with the rear cat delete and X pipe combo are at least 10 rwhp. Looks like the front cats rob less hp than the rears/X pipe. The factory X pipe might be hurting power some even if the cats were gutted compared to a good X like Borla.
