I wouldn't bother with shorties. I put FRPP shorties on my car 4 years ago and they are very little if any gain in performance. It is essentially the same amount of labor to do the long tubes. I will probably replace mine sometime in the near future. But if you do decide to go the shorty route make sure thya are equal length headers. I am not sure who beside BBK make equal length shorties.
thanks for the responses and shortys only give little gain ? so longtubes are they way to go with gt's eh?i guess ill wait for more opinions but if this is true i will need to change my exhuast setup i was just about to order...lol ...on the same note ,are we only looking at 10-15 rwhp with LT headers , hi flo cats and x pipe? last questions with LT's , how will these perform with the procharger?

People that say shorty headers give little to no gains are being slightly misleading IMO. It is true that the PEAK gains from shorty headers are minimal, however, typically shorties offer better LOW TO MID range torque gains than long tubes. So, it comes down to how you drive your car and where do you really want to feel that extra power. At the track, long tubes are the hands down win. For a daily driver that rarely sees the top of RPM range, I think shorties are a better choice.
FWIW, I don't know where you are in CO, but long tubes will not pass emissions if you live on the Front Range. I think JBA shorties are the only 50 state legal headers. Something to think about.

Keep in mind, it doesn't matter if you buy headers with or without cats. Rememoving the [functional] OEM cats is illegal and = failed emissions. Thank the Feds, not the State for that one.
I'm a couple years away from needing an emissions test to register my Mustang, but I'm curious if you can get around the issue of catalytic converters by using the drive-by stations as long as your car is tuned well enough to pass the sniffer. Those mobile emissions vans they put on the freeway on-ramps certainly don't have a visual inspection. I just haven't read or heard of anyone whose done it that way.

ya i do know that about removing cats law , but i did it on my 04 dodge ram where i actually didnt have the cats at all and went and tested and they failed me for not having cats lol so i put em back on and it passed no problem....as far as the sniffers on the highway , i usually let off the gas when i pass them so im not sure if that works or not lol
