I have the 3" ORP that is in my signature on my car and I gathered up enough money to purchase the BBK headers that I want. My car is a dual cat car and I was wondering if anyone knows whether or not my y-pipe will match up to the headers or not?? If not than what size y-pipe will match up to the BBK headers?? Would it be safe to go and buy another y-pipe, perhaps 2 1/2" instead??

If at last option, what other headers might match up to the 3" y-pipe I already have??

 

Mine were SUPPOSED to fit, but I had to get extra pipe from the cat to the Y-pipe. It was only $40 for that install. I'm sure any shop could do what you need if it doesn't fit perfectly.

 

never heard of anyone using these, how are they? what gains? just really curious.

 

i have the MAC ORP and are using the Edelbrock Headers?

 

I have the BBK headers in and it may not fit. On dual cats cars, the passager side headers is a little longer than the stock manifold. I just got a 2 1/2 in y-pipe made for it

 

I have the BBK 93-95 style and I would recommend the SLP 1 3/4" coated shorty headers over the BBK for a bigger gain and easier plug access. I know the SLP's will bolt right up because I've installed them before on a 97 car. If I had to do it all again, I'd go with long tube headers.

Just a suggestion. Might not want to go with BBKs for the gains. If youve ever seen an LT1 head the exhaust ports are D shaped, unlike most ports. Ive heard that BBK still manufactured the flanges with O shaped ports, hence not a good match up. Ive heard this hinders performance. If you cant afford longtubes, go with SLPs or MAC with the Ypipe and offroad. Just my opinion.

 

By using the stock y-pipe, the only problem I had was that the headers bent the Y-pipe so it was touching the frame a little..you need to either cut a bit off the crossmember or bend the Y-pipe just a bit. I have dual cats too...

 

Thanks for the replies guys. Maybe I shouldn't go with the BBKs then huh? How about the Edelbrock TES headers?? Does anyone recommend those over Mac or SLPs?? Chesee48 I noticed you have them in your sig, do you recommend them over the other headers???

 

I have a 96 with bkk's. The plugs are easy to get to except for that last one by the fire wall on the driver side. But a O rachet set from sears fixes that. As far as that Y pipe hookup on the pas. side. Yeah it doesnt match up. You have to cut it and install a new peice that comes with the headers. They give you this exhaust rap thing that you bolt on in place of welding. I just welded it up. Only took me about an hour of tinkering. I dont know about performance. I never been to the dyno in my life. shrug.

 

i have the same question, MAC or Edlebrocks ? By the way what is the size of stock manifolds and Y Pipes on a single cat system? Of all you guys with headers, do most of you run Off road Pipes, i want to run off road pipes but if get pulled over ill fail a visual, should i just gut the cat instead?

 

Out of probably 100 guys with shorties on this board maybe 1 has Edelbrocks or BBKs, that doesnt necessarily mean theyre bad, but theres usually a reason no one buys them, Ive definitely heard bad things about BBk, and a few about edelbrock. If youve got the money go with SLP or ASAM since they are both 1 3/4 primaries compared to 1 5/8 like on all the other shorties. If youre not set on shorties get some hookers jet hot coated and a mufflex ypipe for about 900. For the performance in my opinion get MACs for the money, and SLP or ASAM for a little more cash and even more performance, some people even say that SLP and ASAM perform just as well as longtubes but longtubes have a smoother torque curve. hope that helps

 

MAC's! But i have edel's hehe

 

I just conveted to 94-95 style headers on my 97z, much easier than messing around with all that crap.

 

My old Z28, A4 3.23 with stock stall, and a cc305 with edelbrok shorties went 12.89 @106, so they must not be too terrible
