BBK Shorty Headers Results
Last December I had one of the prototype sets of BBK shorty headers installed on my car. These headers have 1 3/4 in. primaries compared to the other shorties’ 1 5/8 in. and seem to be a better solution for anyone looking to get the most power while staying emissions legal. These headers should overpower the other shorties when more mods are added such as a cam or stage 1 headers. The fit and finish looks great on these as well as the ceramic coating. The headers added a deeper rumble to the exhaust note and made the exhaust noticeably louder under WOT. And for those who say shorties add little to no gains, they are wrong.
I have dynoed before and after the headers, and have just finished testing them out at the track after installation. My only other mod is a Direct Flow lid. On the dyno, the car picked up 10rwhp and 10rwtq everywhere. It vertically shifted my old power curves up 10 and added had the strongest gains from about 4000-5000 rpm. The car is running rich and I feel there is more horsepower to be gained from tuning. Also, the car feels a little stronger now so it may have learned a bit after finally getting over 500 miles on them. I would expect though with more mods, more power will be gained from these.
The track is where these headers really shined for me. I picked up almost 2 tenths in the ¼ mile as well as 1 mph with near matching 60fts. The track results were at the same track and with similar conditions.
I plan to get a new y-pipe for the car and see if I can get close to equaling the gains of long tubes with shorties. I think it can be done on a bolt on only car and will have dyno and track results to either support it or refute it. I do understand that long tubes will be superior with H/C, but with just boltons it will be close.
Overall, I would definitely recommend these to anyone looking to stay emissions legal or keep the exhaust volume down. My car is a 1998 T/A so the gains on a ‘01+ car may not be as good as they seem to have higher flowing manifolds from the factory. I spoke with the head of R&D at BBK and he said these should be available within the next few months. Sorry for the long post, but just wanted to spread the word of my success with these new BBK shorties.
But, for cali, this offers a nice soloution. I always wondered why nobody was releasing any 1.75" shorites for these cars. Nice to see that they are now.
Will BBK be making headers for all the years. Like a '98/'99 set, '00 set, and '01/'02 set? Or will you have to buy the conversion hardware for other years past '98/'99?
Got any pics of the headers? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
My understanding was that they were making 3 differnet versions as the first test car was an 01 and mine was used to test the emissions hook ups for 98-99s. I can get some pictures on the car but you wont be able to see too much over any other hearders. The tubes look a lot bigger than the JBAs. For a close approx. pic imagine these with round openings and they are identical. Seen here.

I had been looking into these headers untill I started hearing that there was lil or now power gains off shorty headers so I started looking into hooker's longtube's my car is a bolt on so I guess I will keep looking at wut other fellows have to say before I make my decision between L.T. or shorties...

see any mention of it; I know JBAs do but
just because it's a shorty, doesn't make
it legal in the merry old land of Oz.
They do look nice though. Still wondering
how just porting the stock '02 exhaust
manifolds would stack up to those 10HP gains,
given the lousy port matching but relatively
nice plumbing otherwise, there.
