Bypassing the smog pump wouldn't be noticeable. If you have cats, you will eventually notice the loss caused by their clogging up.

If you live where emmisions are not checked, you can eleminate the cats and go to a offroad H-pipe configuration (for offroad use only, --wink, wink). You can eliminate the smog pump with an idler pulley from www.windsor-fox.com ,part number IDL-SP, and still use your stock length serpintine belt.
