What ever both of you do... Do your exhaust in all Stainless steel, please... I know its alot more money, but its worth it if you plan to keep your Car more than say 6-8 years ? I always make up my own exhaust systems on everything i have. I buy exhaust parts, and also make up my own pipes. I have been too cheap to pop for stainless steel, but always cuss my self for not spending the money. I keep my Cars and Trucks forever, i never sell anything. Dont make the same mistakes for your exhaust system... wakjob, i like what you picked, i say run with that... Mustang Dad, I say your spot on for your stock 200-250 ?... Side note here.. I have a 83 F150 300 six. Its reworked some for high torque below 4000 RPM. All the proven parts, Offy DP intake, 390 Holley 4 barrel. Pocket ported EFI Cylinder head, short duration Camshaft. I made my own dual exhaust manifolds with 5 foot 2.25 dual pipes going under the cab. I had a nice 3 inch low restriction exhaust i made years back, and the Truck runs well... Now the exhaust has rusted to Hell, and was making too many bad sounds... I got pissed and in a hurry and grabbed some junk laying around. I cut everything off, and left the 5 foot pipes off the engine. I welded up this 4 inch pipe all the way back to the bumper. I welded a cap on the end of that, and cut a hole 2 feet back that blows the exhaust down and out... Part of this was an experiment on sound wave management, and its not too offensive until you get on it. The funny thing is, the Truck runs just a bit better. It makes no sense at all, the 4 inch pipe is too big. What i think that saves this Hillbilly exhaust is, the 5 foot dual 2.25 head pipes. And the 4 inch pipe, is just a tuned chamber. The hole at the bottom is just 2x3 inches... Im confused why this works well, maybe others have ideas... Dont mean to jack this thread, but i thought this info was useful to all.
