Got a deal on a used Lethal catless H pipe. I know longtubes drop boost while increasing horsepower, which is always a good thing; does a catless h-pipe drop boost as well? I am at roughly 16 lbs of boost right now.
From the OEM catted mid pipe? yes it should, at least a pound or two. Cats are obviously a huge restriction. Headers would drop it even more because of their way better efficiency at scavenging.
