2000GT4.6, BBK makes equal length shorties. A bitch to install, but they have them. Only make 1-4 HP over the FRPP shorties, so not really worth the hassle.

The FRPP shorties are not all that bad. They are stainless and you can buy them with Jet Hot for $335 on ebay. Long tubes are great for racing, I'll grant you that, but for us average street guys, shorties are fine.

ANYWAY, ZW99GT, did you install a CAI? All those mods are nice, but if you're running without a CAI, that would explain some of the rich F/A issue. Your motor may just need to breathe.

I would also recommend a timing adjuster to advance the timing.
