Has anyone removed or bypassed their smog pump, and if so did they notice an improvement in performance. Also I will be retaining my catalytic converters, so will I have problems with burning them up? Any opinions would be appreciated.

I bypassed my smogpump with a smaller belt and i still have my cats. I did notice a little difference afterwards. Must have been clogged up or something...or whatever would cause resistance. But so far my cats are fine.

why bother to remove the pump if you leave the cats? you get more power by removing the cats then you would by bypassing the pump if your going to have to pass smog again, just buy a catless h-pipe. its not that hard to install.

Yeah i am going to cut out my cats here in a week or two. Just waiting for my welder to have some free time...

hey negadive, what size belt did u use?

NegadivOne

I used an 84". it fits perfectly. after being driven for a while and stretched out its still right exactly in the middle of the acceptable tension range.

bobby

thatsn kool, thanks, now i know what size to use, did u have any clerence issue? like when the belt comes around does it hit on the idler pulley? or did u have to relocate the idler pulley?

NegadivOne

Nope. Everything is fine. you know how to route it right?

bobby

NegadivOne

Nope. All stock.
