Default Shorty header question, please help

Sorry in advance for the redundancy..

Can you folks w/ experience (or an educated guess) please chime in?

I'm looking to put a set of short tube headers on my bone-stock 2000 FRC while everything is apart during my gear swap.

Please don't try to convince me to go long-tube; I'm fully aware of the up and down-sides..

What I'm looking for is who makes the best fit / highest quality / HP gain / cost, etc.

There are tons of posts regarding long tubes, but few for what I'm looking for. I want to keep everything stock from the exhaust manifolds back. I've felt how heavy the stock part is, and even if it's just for weight savings and 10 or so HP, that's fine with me. Thanks in advance.

Not anyone wants to reply because they are going to tell you to get LT's. JBA just enetered into the C5 LT header market at the price of 750.00 for a set. So if price was an issue, not any more. Good luck, but if you do not go LT's do not go at all. My .02 here.

If your not going to go to long tubed headers stick with your stock exhaust. I had shorties on my Z-28 and it was a waste of money. Spend the money on other upgrades.

Basically JBA and B&B for shorties, BBK is junk. Less weight and maybe 5-10 HP. JBA is ss and coated which should be better. T-Byrne sells 'em.

Default headers

if you do not go to the track,and want something for the street go shortys good low end torgue. the s/s headers look good fit good and are easy to put on. the b&bs are what i used in the past, If you go this route i have a new set still in the box. pd. $1100+shipping,sell 4 $900+shipping. my new motor pkg. comes with the long tubs for the track.

I have B&B Tri Flo shorties on my 00 Coupe that I installed myself. Fit is good to manifold but dip stick mount was a mile off & had to modify it to work. Match to stock cats also good.

If you have the newer exhaust manifolds, which are better than the 99 thru 2000, then I would say the swap would not benefit too much. SInce you do have the older style manifolds, the shorties will give you a small gain in performance. I gained about 13 rwhp on a heads and cam car. Everybody on the Forum says it's a waste of time and money, but in Calif. we can only run shorties. SHorties do have the advantage of ground clearance over LT's. Most LT's must be removed with a clutch change, while shorties stay in place. I'm running BBK shorties, but I would not recommend them only because the flanges on my set were not true (header to head flanges). I spent many hours hand lapping them on a piece of flat granite and a sanding belt. I also had them TIG welded on the low areas. They are perfectly flat now and do not have the slightest leak. They were easy to install but I had the same problem as Fred, the oil dipstick holder bracket was off.

Im advising you from experience..."dont do shorties" It will give you zero gains so your literally throwing money away.

I'll take your 300 bucks if you really dont need it!

The early '97-98 cast iron manifolds are individual runners nearly to the outlet, the later '99-00 double-wall sheet metal manifolds are log style. The cast iron manifolds flow better than the sheet metal version. I don't know about 2001-on.

They went to a cast iron manifold in 2001 to 2004 with runners and a sheetmetal heat shield..much better.

I've got a 99 coupe with the Borla shorties and the 4 tip stinger exhaust, I actually feel the low end torque increase when humming around town at 10-15 mph and then punch it, I would guess it was probably a 20 RWHP gain with the exhaust though. I then put in a Vararoom intake system and felt the biggest jump in power, I think the shorties alone will give you min power gains but in combination with other componets, it's well worth it. The LS1 really comes alive when you let it breath better. Rem: more air in and more air out makes for more power. Good luck!! I know everyone like LT and yes your going to get more gains, but sometimes LT aren't for everyone. Though I did put them on my 94 LT1 383 Stroker Motor.

I have a 98 a4. would I be just as well off to forget Long tubes and just replace the cats with better flowing ones?
