automotive exhaust

[bill nye scienceguy!]

Hi, can anyone point me in the direction of some good information relating to the design of automotive exhausts? In particular design of headers and calculations for noise attenuation.

Thanks!

Sure. Winterbone et al published a fantastic paper on the theory of manifold design, which should be a really good step in the right direction. Also Blair's book, "design and simulation of four stroke engines" has some excellent stuff on runner design.

It might not be noise attenuation, but I recall A. Bell's "Performance Tuning for the Four-Stroke Engine" as being EXTREMELY interesting with lots of material on exhaust and intake systems.

can you give me the full title of the paper? I've had trouble finding it with just the author's name as a search reference. I've tried arxiv, scirus and my university's library to no avail.

Yep. It's Winterbone, D.E. and Pearson, R.J. Theory of Engine Manifold Design, Warrendale, PA: SAE 2000
