Oval exhaust piping

[Guest jjohart]

In the course of this week's install of I/C and 3 inch exhaust and downpipe, my installer mentioned that oval pipes are beneficial to flow. Can someone offer a brief explanation of why this may be so, if the gains are so nominal as to be a waste of money over standard pipes?

Thanks

Did your installer offer any explanation? I have heard that they flow marginally better around bends, but that is all I have heard.

where to get them, that's my question.

Burns Stainless sells oval tubing.

I`ve never heard of any benefits of oval mandrel bent pipe over round mandrel bent exhaust pipe.

 

The only true benefit that I can see is for ground clearance.

I think the only real benefit is ground clearance going under low cars.

The only real advantages of oval tubing are:

1) It can be bent in a tighter radius without crimping the tubing, and

2) It gives better ground clearance where it runs under the rear half shafts.

Unless either of those two items are needed I would stick with round - much more common, easier to work with, and less expensive.

I looked at oval because of running a 3 1/2" exhaust on the LS1 but am going to try to stick with round.
