Im running bbk long tubes off my 408W. What hooks up to them thats 3inches? Mac pipes look like they might have the same type of flange adapter. Any info would be appreciated

The bbk flange is 2.5''. If you cut the flange off,3'' pipe lines up pretty well with a butt joint band clamp.
I use a universal x,with hard mounts welded on each side. Not a bolt on,will take some fab work.

Had the car up in the air at a friends shop to change a speedo gear,snapped a few pics.
Nothing fancy,just some bent flatstock welded to the pipe and bolted to the d/s loop.

Would have liked to see the collectors and how you did them

I think they're a little easier to get off

I’ve actually mic’d a set of flanges on the bbk 3in collectors and they’re pretty small, like less than 2.3in ID. I’d cut those things off.

Oh yea they are way to small. Im going to chop as much off as i can. I found a set of 3in ball flange adapters that i could weld a 3in pipe to. Ill try that. If not, hack the whole flange off!
