just a b pipe welding question?

[8ball]

So I bought a a4 manifold from the salvage yard but I noticed that they cut off the collector flange that hooks up to the catalytic converter.

Just wondering if a muffler shop could weld the collector I have on now from the a1 manifold to the a4 manifold?

Best to ask them... but welding a flange is pretty much a daily task for a muffler shop.

Yeah ill do that. I sent my car to be repaired (for a clutch) and I guess the "mechanic" got a little gas happy and must have racked the curb and through my caster off and squished my b pip litterally 3/4 of an inch ... :/

You should see DJ_Enders down pipe he might have a 1/2 of flow left on a 2 1/4 DP.
