Trying to stay legal in CA here (and the rest of the country for the matter)...looking into shorty headers, specifically BBK 1.75" headers. Anybody have these? Any noticeable power increase?
(It says 10-12rwhp) Change in exhaust tone? Lemme know your experience with these.

Thanks

 

No experience on a vette..but I added a set onto my LS1 Camaro...and I noted a deeper exaust note ...noticable SOTP performance change..

Id say find a used set and you cant go wrong....

Youll get a butt load of hateers...but livin in CA we pay the price

 

do a search for shorty headers....plenty of threads to read.

 

Yes, I have them. Yes they look nice. Not sure of the power increase but my Z dyno'd 371 rwhp with just the headers which is slightly higher than most. I still wonder if they are really CARB approved since there isn't any CARB number on them. We'll see when I have to get 'er smogged.

 

Pace setter brand new on E*** for $279.99 shorty headers.

 

Not ALL shorty headers are legal...........

Make sure they have a CARB EO# for your specific application!!!

 

Look for some BBk ceramic coated shorty headers!

 

I have been looking into this for a while trying to decide wich way to go and I have only been able to find carb numbers for B&B,Borla,JBA,Doug Thorley,Callaway,and Pace Setter. You can get Pace setters for about 290.00 but they are only 1 5/8 tubes all of the others are 1 3/4 Borla discontinued there shortys they were pretty expensive about 1200.00 dollars but they seem to be pretty good from what I have read and you can find them cheaper if you look around I found a new set for 649.00 the Doug Thorleys and JBA both have pretty short primary tubes The B&B`s Tri Flow is probably the best but they are expensive there is a set on E Bay right now with a bid of under 300.00 with about a day to go for a 2001 2004 I would be all over them but my car is a 2000 also I looked up BBK headers for a C5 on the C.A clean air website(That was given to me by another member that was verry helpfull) and could not find a C.A.R.B # for them I don,t think they are legal in C.A I think some people get BBK confused with B&B. I would Like the B&B,s but for the little power you do get unless I can find a used set I probably won`t spend the 12500.00 dollars they are asking for them. If I can`t find a used set after a while I will probably go with the Borla headers for 649.00 have to decide pretty soon before they are all gone...Good Luck

 

what is wrong with the Pace setter 1 5/8?

 

nothing wrong with 1 5/8 at all I just prefer 1 3/4 especialy for a shorty. In my opinion a shorty will allready have plenty of bottom end if it`s 1 5/8 or 1 3/4 so I am kinda leaning towads the 1 3/4 because it might give me a little better flow throughout the RPM range. I think that`s why most of them are 1 3/4. Pace Setter has a great looking header for a nice price and I allmost went that way. I think the 1 3/4 headers are a little more expensive because they might be a little harder to produce...either way I guess it just personal preference. From everything I have read you are not going to gain a whole lot either way but every little bit helps...I guess

 

Do an X pipe and cat back and you will notice a small difference is power and a much better exhaust sound. Long tube headers work (30 to 40 HP) but the shorties are a waste of money, they really wont be any different than the stock headers

 

Are there any differences between 2000 exhaust manifolds and 2001 to 2004 or the 2002to 2004 ZO6 I know the smog connections are different I mean are the manifold shapes different. I have seen pictures and mine look alot smaller at the O2 sensor and the runners are not as pronounced that`s why I was thinking of changing..Allready have Corsa Pace exhaust just put it on and love it.Magnaflow X pipe on the way I am changing heads(243`s with mild port and polish).Cam,LS6 intake,LS6 M.A.F ,ported TB,Vararam intake with power duct then having tuned by Nick at Newtech when I get it done just thinking the headers might help a little over my stock manifolds and still stay smog legal except for the intake wich won`t be to hard to change every two years or might be overlooked all together if I take off the decal.Just trying to get all I can out of her

 

"The exhaust manifolds on the LS6 and 2001 LS1s are new cast iron items. Previously, the LS1 used a double-wall, fabricated, stainless-steel manifold. Most ’97-’00 LS1s had cats downstream in the exhaust under the floor. Double-walls, available only with a fabricated manifold, were required to retain exhaust heat in the interest of quicker light-off of the catalytic converters. The addition of pup cats, immediately below the exhaust manifolds on ’00 California cars and all ’01s, eliminated the need for the stainless manifolds.
The new iron manifolds offer improved exhaust flow compared to the stainless units but, currently, the LS6 doesn’t need the improvement. There will be further performance enhancement for MY02 enough that the extra flow will be needed. The iron manifolds offer better durability, too. They don’t crack at welds as can stainless manifolds and, believe it or not, because of the type of iron used, they will tolerate a higher level of exhaust heat."

Thanks I learn so much here.... so basicly my car has the stainless manifolds wich are not as good. I thought they were different. I guess I could run the newer manifolds but I would have to change the smog tubes wich probably wouldn`t be to hard to do. I am no expert on the corvette(this is my first one) but I think the manifolds I have will hurt me a little probably why GM made them better in later years.

 

Those on the bay are not B&B..thier "BB" and then further down their listed as BBK 1..I smell a scam

 

The ones that I saw were B&B allready sold earlier today they were B&B for sure the guy took a picture of the C.A.R.B number on the headers he paid almost 1200.00 for them a month ago and they sold for around three hundred I wish I had a 2001 to 2004. The other ones you are looking at are BBK I saw them to

 

B&B's are the only shorties to but IMO. They feature equal length primaries designed for improved exhaust scavenging and that's what sets them apart from their competitors. They're dyno proven for 10-12 rwhp.

I picked up a used set and had the ceramic coated, and I couldn't be happier with my choice. Going with LT's in CA and having to swap them out for stock every two years to pass smog is not worth another 10rwhp to me.
