Header Question

Hey guys, been going throught he knowledge base, but cant seem to get what i am looking for. I was wondering if anyone can tell me why one set of JBA headers costs an arm and a leg, while i have found many others for mush less. I was looking to rebuild my 289, but im not sure what i should be looking for. As i have mentioned before, its going to be an everyday driver, but i want to improve performance. Does this mean that i have to spend a ton of money on headers. Also, i see the term "shorteys" appear alot, can someone tell me what this means? Thanks again everyone.

"Shorty" headers have shorter tubes that merge into an exhaust pipe well above the lower part of the car body. They don't work quite as well as long-tube headers, but they offer much better ground clearance. Look at a stock 87-up 5.0 Mustang & you will see shorty headers.

Shorty headers are for lower RPM operations, such as everyday driving. To say they do not work quite as well as full length headers is not totally correct. Full lenght headers perform better than shorty headers for WOT use, such as drag racing. If you do a search for Sanderson headers, they have a very good tech section on the website that explains this.

You just cant beat a set of Thorley tri Y's for your 289. I have heard good and bad about JBA. No personal experience with them. If you are looking for an economical alternitive try any mustang supply for a set of uncoated Shelby style tri y's and coat them with some POR manifold paint. Just a thought.
