Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Default Catalytic Converters finally give up!

So have JBA Ceramic Shorty Headers and a JBA Cat back. Duece has 135,000 on it with a Magnusson Supercharger. The Blower was installed at about 20,000 miles so alot of boosted miles on a stock motor and stock cats.

Towing my trailer on the way to the Anza/Borrego Off Road Area the check engine light came on and the engine temps started to spike. i shut it down and plugged in my $89.95 trusty made in china scanner and up popped the bank one, cat efficiency code. Took out my Tire Iron, proceeded to poke hole in cat to get at the loose peice of screen that I could hear rattling around inside it and clogging my exhaust. ran like a champ after that. got home from my trip and replaced both cats.

Ok guys. I ordered the ARP bolts... what gasket do I need. I’m looking on Amazon so I can get them by Sunday.

I hope i dont brake any if any of the bolts. I guess I’ll use a torch and heat up around the bolt before I try them. And I think you guys were saying to remove the fender liners?

Best manifold/header gaskets you can buy are Remflex #2008.... Good for both the 6.0 and the 6.2.
