removing the cats but leaving the super restrictive stock H is rather pointless. While you will have gains, probably closer to 5hp compared to removing the cats and swapping to a 3" mid pipe.

The stock H is mostly restricted to 2.25".

Who makes a quality O/R H pipe that'll bolt up to stock manifolds and OTA pipes without costing a crap load?

i had all my piping welded in no clamps

i have never used clamps on a exhaust set welded or not at all.im replacing the resonators next week with 3inch dynomax race bullets to clean up the sound alittle i was told that they work good giving a more deep tone

Sweet, I think I'm actually going to just hold off until I get LT's and do it all at once.
