Mid lengths should be emissions legal. I wouldnt waste my time with shortys if mids could be had legally. Much more gain with mids than shortys.
PS - Luckily KY has no emissions, so I'm going LT.

I've got 93 style SLP's on my 1997 !
I love them, I did away with EGR and AIR so having these wasnt a problem. They fit great and woke the car up a lil bit, I like these over the 96-97 style because they are a single cat and are almost a mid-length header over the what I feel is a crap design for the 96-97 dual cat cars....
I'd say the SLP's are good quality !!!

, lol To make them work you would have to buy the header EGR blockoff plate, and use the properly sized fittings along with a length of flex pipe to extend the Secondary AIR injection tube forward to the connection.
ALL LT1 heads from 92-97 have the same bolt pattern and spacing for the headers. The only major differences was emissions tubing locations and Y-pipe versions (single vs. dual cat).
94FormulaT/A's headers will work with your 93, you just have to do a little extra part work to get the AIR tubes set right. Or just block them all off and happy motoring.

Ok i talked to my mechanic...and he explained what you said to me, my midunderstanding from you to him...ill buy them then :thumbsup:.....though i do ask if if you could locate some 'flex pipe' or something that will fit to hook up the everything correctly since you have the headers...if not no biggie
- now im happy
If you can call me so we can get these things worked out
- Will
