Aluminum 7068 is the latest alloy making its' way into DoD/Aerospace applications. Combines the strength of steel with the weight of Alu and is used where high strength is required along with good resistance to corrosion and temp cycling fatigue, you might want to look at that. Can be ordered in tubes, bars and rounds of all sizes.
... and not that new, but the qualification programs for aerospace are extreme and take years to complete when fully characterizing end-of-life failure modes.
Thanks for input. 7068 sounds like the best choice, if available ( cost ) , if not maybe 7075. My neighbor is an aerospace engineer, so i will pick his brain on monday.
I used Howell Racing mufflers as they make a great performance muflfer that is 4 inch round outside and 3 1/2 inches inside and the right length for a Cobra. Now if you like them a bit louder like me, turn them around backwards. Running a all aluminum 496 FE 681HP and it sounds and runs great........
Thanks for your input Gary, but what i am looking for is dual purpose muffler. The engine should dyno over 700hp now , so i need at least a 3" perforated core on track days and play days. Driving around neighborhood i need to lower the decibels.

Thanks again for the help
If your neighbor says yeah we use it, the next question you should ask is "can I get a peek at the scrap?" You would be suprised at what these companies throw away
