: B&B 3" Front Pipes

I bought a used B&B but it came with front pipes that were fabbed for Kooks headers. :banghead:

I may do headers down the road, but I'm doing some Fstock Ax right now.

Does anyone have the std 3" pipes that connect the x-pipe to the stock cats that they want to sell? Also does the exhaust require a gasket at the cat connection? If so what does it look like? Thanks.

You can buy the connector pipes from B&B.

You will need gaskets and an adapter as the cat connection is 2.5" and the B&B is 3" diameter.

Furthermore, the stock connection fits into each other whereas the B&B is a flush mount.

My $.02?

Get the headers and cats and match the stuff up.

Where do I get the adapter? I will call B&B tomorrow and see if they have it. I was just thinking I could possibly get the connector pipes for less from someone here.

Any good exhaust shop should be able to fab you up an adapter.

The caveat?

Probably won't be stainless.

Just a gasket, a flange with a pipe welded and bent and a clamp X2.

You have to have a mating flange that is 2.5".

Then you need to have the diameter of the pipe stretched out to 3".

Sounds like a lot of work. Get the kooks headers and move on ...:sneaky:

So does everyone on here with the B&B have this custom adapter with stock cats and manifolds? I thought most catbacks are simple bolt ons. Any Pics?

Sounds like too much work. You should just give up now and send me the X-Pipe.:bouncy::bouncy:

Mine was a "simple" bolt-on, although the shop I had install it managed to screw it up by unthreading the cat flange studs, then re-installing them like a bolt, :banghead: cross-threading them in the process. Prime example of Murphy's Law.

I got new donut gaskets and flange studs from Luke @ Lindsay, drilled out the now sheared off studs, and ran a tap through the flange holes. Put the new studs in and slowly tightened the retaining nuts evenly and ... no leaks for 2 yrs.

Anyway..... the flange plate on the 3" B&B pipe draws up fine to the flange plate on the OEM cats.

My B&B is over 3 yrs old with a 'mini' resonator built into each header pipe before the actual resonator. I assume they are still building them now to the same dimensions, but I don't think they use the small resonator anymore in the head pipe.
