When I bought my 1974 360 Challenger it had 3" pipe and flowmasters off the headers. It was loud, and gutless. I bought one of the Jegs $200 mandrel bent exhaust kits with mufflers in the 2.5" size. The car picked up quite a bit and sounded better out of the exhaust tips.
I am lowering the car, removing the headers, and putting '70-'71 high flow factory exhaust manifolds on it. I will make up the required pipe to join up to the Jegs setup and will likely add a set of electic cutouts for fun (that might exit something like the T/A pipe).
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!
