[QUOTE="Uncle Meat, post: 16240830, member: 5089"] While removing a functioning factory catalytic converter and replacing it with a less restrictive one seems like it would be okay, it's not. There's all sorts of state & federal regulations which make this a no-no. The 1990 Clean Air Act Amendment is just one of the regs which covers the replacement of catalytic converters and what's allowed and what's not. I did. I shopped around a bit before making the decision to go with Katech. True dat. Katech did a lot of work for GM on the C5-R. No problem with over-cam'ing the car. The car is not tracked or raced. The wife and I use it for long distance car runs around the country so stock drive-ability and reliability are big concerns. I'll be going with one of the mildest LS7 cams they have, a Torquer 116. As for a better intake than the FAST... it's what Katech uses in their "Stage 2" package. I'm not trying to make a monster with this car. I just want a bit more power across the board, a more aggressive exhaust note, and heads that I don't have to worry about dropping a valve. I'll have to take a look at those valve covers from Holley... U.M. [/QUOTE]
