Back in the old days, your basic mods were aluminum intake, holley 4 barrel dbl pumper, headers and hush thrush or glass packs. If you got ambitious, you changed out a cam, pop up pistons, head changes, and rear end changes. Of course that was back in day of when gas was less than .50 a gallon, you could buy leaded hi test.
I guess we are doing the intake thing. CAI and tuners and the glass packs have given way to borla, magna and the like.
I know with all the EGR, Smog, save the planet stuff, have headers become obselete? I am not talking about the straight, non emission friendly type. I am talking about the ones that will work with the emissions on your car and pass local emission (other than calif.) :scratch: . I know JBA have a set, FOMOCO has a few sets.
What are the advantages of headers now a days?
What is the HP gain?
PS I would also like a sticky with the common bolt on's and the HP increase. (please include model and type)
CAI's w/ tuners HP increase
Cat back pipes HP increase
Manifold back x pipe HP increase
Pulley change HP increase
Headers HP increase
Rear end changes (list gear type) HP increase

Headers will give some up end hp at the loss of low end torque and they look cool, but I would be surprised at any more than 5 hp increase on my rig.
Ceramic covering will lower the under hood temp which may give me a few more hp.
The cost of putting on new motor mounts and the headers themselves have put this last on my list.

Run a search, a couple of folks have dicussed headers before. 38 special called it, from what I've seen, about 5 for shorties and 10 for long tubes. The new exhaust manifolds are much better. I'm saying 10 for long tubes because they are usually ran with high flow or no cats and a x-pipe. 10 for LTs, 6-7 for cats and pipe.

I'm not for sure, but I thought Bassani or someone was claiming a 20hp increase with their entire system (headers, x-pipe, mufflers) without a tune. 40hp with tune. I realize that is their claim and it wouldn't pass emissions, but that would be quite a bump.

Long tube header's were the first performance mod I did....I don't have to talk about'em they speak for themselve's! I love them (JBA's), and with the off-road H-pipe I gained 22 RWHP and 20 ft-Ibs. of RWTQ.

Has anyone tested he Hooker Headers system? I haven't been into cars all that long, but they have a good name in the motorcycle world. That plus the fact that they're a classic name and the 05's have such a classic style. I just think they'd go well together. But I would prefer someone else try first and save me the $$$, just in case the Bassani's are better.

I have a set of Hookers in my garage waiting to go in, along with a TCI converter and a Zex N2O kit.

Cool keep us up to date. I plan on getting the complete system after I get my shaker hood. Then I'll get a CAI, exhaust and tune all at the same time. It ought to be quite the bump in sound and performance.

Rrobello has the JBA cat4ward headers on his. He is running K&N intake, headers, and straight pipes. His car sounds like a race car...and it pulls hard. Not sure on the gains.

JBA long tubes with no cats. I ran 12.90's with true street radials and stock gears . The only mods at the time were headers/CAI/Tune and a set of lower control arms. I netted a total of 295 rwhp after these mods, with my initial bieng 265 rwhp.
