Are the B&B headers any good, anyone know? I'm talking about headers legal in CA (short tubes), except that these are supposed to be far better in terms of horses because of the stepped primaries.

Will I have more power than regular shorties? Or more specifically, is it worthwhile to install them instead of regular headers? I'd like to know in case I will save some money with these compared to sets of headers running $2000+.

I've run the numbers, typically gains will be zero to fifteen, although regular headers are expensive, so unsure whether or not they will be awesome.

Yes....
The shorty haters will be here in a bit..

Shorty headers seem to pretty close in out put..
I like mine.. No you wont get as much as you would if you ran long tubes.. and If your state will allow you to run long tubes then Id go that way...

But yes they are worth the bucks considering the reasons above.. Prices between shorties and long tubes aren that diffrent ~100 bucks

If you want better breathing tubes and live in a state where you can't use long tubes.. then shorties are the way to go and B&B seem to be the favored pipes.. for what ever reasons

And a word about their legality.. B&B's are ONLY legal for Corvette coupes.. NOT the Z06 in CA

I can probably run a set of B&B's for a couple of years. No reason I can't increase the horsepower with supporting mods to be able to make up some of the horses with long tubes. They're going to be leaps and bounds better than stock exhaust manifolds, mostly because of power remaining running unequal length primaries.

Remember also shorties don't have enough scavenging to be effective in terms of efficiency, you're not going anywhere in reference to the horses you can get compared to long tubes. Of course, that's not the reason to run shorties, the reason is the advantage gained with the tubes allowing the motor to pump more air.

I've seen good results with shorties. By nature of design long tubes give better low to midrange. But peak power is fairly close with a good shorty.

That's exactly what I'm talking about, with headers you don't have to worry about straw breathing. I realize it's not the same with larger primaries, then we're talking about cubic inches times efficiency, which of course is another story. Irregardless, it's nice with the options with these sorts of choices because of the power gained for matched modifications.

Save your money and get LTs.

If you're going to spend that kind of money I would probably say no. Honestly, I'm not really convinced LT's are worth it for the money.

My car had a Vararam and a tune and I picked up 16 hp / 13 tq adding Kooks 1 7/8 headers, no cats along with a re-tune. Now, the sound I picked up on the other hand.

I have a set of b&b shorty headers that fit 01-04 vette if anyone is interested!

Read the article in the link below. C5 Corvette factory manifolds are not of the log type design, they are closer to a Tri-Y shorty header. In the article they are tested against LT headers and F-body cast iron exhaust manifolds. When I added Kooks LT headers to my almost stock C5 with a tune and retuned for the headers I gained 8 rwhp and about the same rwtq. I was catless with both setups so the comparison was fair. I think it would be safe to assume the B&B shorties would not offer very much more than your factory manifolds if run through factory cats.

That test is flawed way more than I can count. First of all it's a regular Corvette. Therefore they don't have the cam that can take advantage of the higher breathing for our engines. Also without supporting boltons headers themselves will not increase the horses enough to be good, in other words that's the wrong setup.

Hey d*ckhead, you are the one asking if "shorty headers" are worth it so don't just regurgitate something you read and act like you know all about volumetric efficiency. I took my time to post helpful information and you reply like a "know it all". The tests in the article are relevant and with different cam, heads or intake the results would change but the change would not be dramatic with a basically stock vehicle.

Hitman227

Lol, I'm sorry if your material is worthless, that's not my problem. Go ahead and install a cam with no induction then fat swaybars with no shocks, I'll let you know if it works.

NemesisC5

I've gone far beyond you punk, both on roadcourse and street weapon.

NemesisC5

You showcased your "extensive skillzzz" and knowledge of Corvettes by posting this remedial thread. Are you 5 years old? Put slicks on you tricycle and put the power down.

You're trolling hard and we're not even in the CFOT.

Hitman227

The fact of the matter is, without supporting mods, your car goes nowhere.

anothertoy

So, let me get this straight, you ask the forum for help, you get relative information that isn't what you want to hear, and you're a ***** about it???? It seems like you already know everything. Why ask any questions on the forum?????

novafx4

Oh I see, I need the Alpine CDR/Amp/9S and Garmin 765T performance mods you've listed in your profile. How much HP do they add?
