The guy who tuned my 404s had me passing emissions - they are not that high-strung at all. If not a little timing adjustment should square you away. Scotty had me passing on 403s as well. The weight reduction for traction bars is a win-win. Also, a notch on the subframe (and boxing it back in) is no biggy either. All of those things are easily resolved. I've yet to be tuned on the 405s but if I don't pass I have a work-around...

Scotty tuned my 403's and I passed emissions with flying colors. Even better than I did stock!Originally Posted by BABY J
I hear a lot about the Kidd headers.
What makes them so great and how do they help make so much more power than other headers?
Just call me DAD!
