Shorties are only a waste of money, if their un-equal length..if you go with JBA equal length shorties, they have a feature called a firecone merge collector, which scavages exhaust gases, simular to that, of long tube headers.....JBA Cat4ward® Headers :: 05-06 Ford Mustang 4.6L 3v V8bigcat said:shorties are a direct replacment for the cast iron manifolds that you have now, no modifications needed to install. long tubes are preferred, because you get a better gain. shorties are a waste of $$$ when you consider the amount of power they produce.

As to why FRPP doesn't do LT headers ?? I honestly cannot provide an answer for you on that one, StangDude..However if you give the FRPP tech line a call, I'm sure someone in their dept. would be more than happy to answer you're question..the tech line Ph.# is...(586) 468-1356PDXStangDude said:Alright... someone does there homework!!
I guess my real question is why FRPP doesn't do LT headers? But none the less good info from red05bullitgt!
I looked at those JBL shorties and JBL's marketing has them giving a stang 21.3HP overall gains. That is pretty good but I can only trust marketing so far.

I know what you mean, I was just referring that, as an example to another member and to other members, who may not be aware of, or may not know the difference between an un-equal length shorty and an equal length..As for myself personally, I have no plans on replacing the stock manifolds.. From what I understand, there really isn't that much of a restriction, that would justify replacing them..Maybe down the road, I may go with LT headers, depending on if, there's a huge enough HP. and torque gain, otherwise if not..why even bother ? But on the other hand, if I were..I would pick JBA, there a very reputible company, who does back up their claims, through R&D testing, and researchbigcat said:i generalized the "shorty" headers. the JBA is a little different. the FRPP, for example, is a true shorty header that is not eqaul length. its a direct replacement for the stock manifolds, like i said. it does look better, but does not offer substantial power gains. the FRPP was the main brand in this topic, so i used them as reference for my reply.
I would start out, by getting a dealer list from JBA, as to who may carry their products, in you're local area. Or try places like, Summit racing, Mustangs Unlimited, Steeda, any of the internet speedshops, even try partshopper which is sponsored, by this forum..I'm sure you'll find someone who can offer a good price, on JBA products..lostsoul said:agreed.. I dont have the $$ for LT's.. but the jba st looks good. I wonder where I can get them for cheap? .. I plan to do 12+ lbs of boost.. On jba's add they also test ti with the full cat back and who knows what else.. I wonder what the real power gain is.. I hate how people fudge on the numbers like that.. but looks like everyone does
