I know the size of course is different but what makes them different from each other. OH and who makes a good cheaper set of long tube headers for the 3rd gens price no more than $220

The differences between shorties and long tubes are the length of the primary tubes from heads to collector, and the routing. Shorties end up beside the engine and use a single pipe to route the exhaust from there. Long tubes continue below the engine and bend back to the rear of the car. On 3rd gens, long tubes make it hard to route the exhaust on back without sacrificing ground clearance.

Hedman 68460 are $120 from Summit. The real expense will be hooking up an exhaust system to them.

is there any performance differences though

Long tubes have the advantage with higher power, more extensively modified engines. On the street - probably couldn't tell the difference except for the number of speed bump scrapes.

Hey thanks thats what I needed to know

Third Gens don't have much ground clearance anyway. A set of long-tubes will make it worse.

I used to have long tube headers on my old first-gen Camaro. Never again, too much ground clearance problems with speedbumps and crap like that. Gimmie shorties!!

The difference is that long tubes make more power.
