Kirkham side exhaust

[Cobra #3170]

I have gone through two sets of mild steel exhausts because of corrosion and have switched to stainless with good results. I don't know what collector Kirkham is using but if it is like the original you are leaving HP on the table, a modern collector helps a lot.

There new system is a 4-1 collector which exits outside the car, so its a modern design for performance and unrestrictive flow, but does not look original, and the mufflers are made by Coast Fab exhaust, they only make the mufflers for them with a 3 inch core, very unrestrictive, the headers are made my Kirkham with there new manderal bending tool, Coast fab is a company that makes exhaust for formula one cars out of California, from what the Kirkhams say this new SS set up is the least restrictive thay have seen and used. Perfect for a 600hp plus engine.

Coast Fab makes very good mufflers they are right about that. Originals exited outside the car too, the problem with the collector was that the individual pipes curved into the collector unlike a modern merge collector.

You know ive said it before, I value your opinion on cobras most on this site, thanks for all the info and help.

In addition to corrosion resistance there is one additional benefit to stainless relative to mild steel. It is much harder, which makes it significantly more abrasion resistant in the throw area of the front tire. If you look at cars that have some miles on them this area is quite beat up, minus paint, coating, etc. My polished stainless headers have almost imperceptible pits in this area at 2k miles.
