I can get hold on a 4-2-1 manifold cheap. However it has a 2 inch long dent in the bottom. Will this cause it to lose performance?

How deeps the dent?

Enough to obstruct flow?

If im looking at the right dent, it will probably have no noticeable effect on performance to be honest.

It needs a tidy. I'm going to rub it down, and paint it in black heat resistant paint, although i'm sure it wont stay black for long .

would cutting out the dent and rewelding a section of pipe back on be worth it?
