1964 Plymouth Valiant-3'' Exhaust

Thanks for the info. I'm curious what year, make and model you have. FYI-I've got manifolds now and don't plan on installing headers. Realize that sounds confusing (2'' outlet to 3'' exhaust), but if I keep this car, I'm putting in a big block (413, 426). A more high output/cube motor justifies going 3'' and as a bonus, I won't have to redo or respend. One and done, and the versatility should performance be tweaked in the future. BTW-This all started when a B body 3'' Flowmaster kit went up for sale and got my wheels turning. Called Flowmaster's tech department to see what mods would be needed to adapt to my car and the culprit ended up being the tail pipes. I'm not that handy and don't have a garage, so the exhaust shop will definitely be doing all the work. The question is: do I request 3'' or 2.5''. I'm thinking a good shop might just recommend going smaller from the start. It actually has 2'' or 1 7/8 on there now, so either will be an improvement.

Does not sound confusing at all, you planned it ahead, can cure any problems long before you do the trans plant. And the way it sounds, you will more than likely keep the car.
What happened was I was chasing a '68 Cuda and ended up taking a left, dead end road, and a clean but well used '75 Dodge Dart appeared. Really rough mechanically, raced to death, no history with the car......wife loved it, she got my attention when I was under the hood-so many tell tale sign's of this could be her, our last ride. So, preview of the garage shot is: 1975 Dodge Dart Sport, 318 Cu In block, Edelbrock Performer heads, intake, had a Holley 650 double-gonna be a doorstop-pumper at that time, flat cam and well used unknowns inside. We cashed the lady out that owned it, drove it 30 miles home and parked it to try and dial it in, which led me to start taking inventory. Hedman hedders were coupled up to same size collector/exhaust, H crossover had been cut out, quasi mufflers/empty "Customized" FlowMaster cans, over the rear end and ot to the chrome tips. Few pic's I tried to get-we don't have a garage, barn, or shop, we have a driveway, and some shade trees.
The pic's are not perfect, but there fresh ;) .
Remember, we bought it basically this way, it is a work in progress, my wife loves iy, you know how that goes, I love her and it's our "Baby". And it's not a Duster....
It rub's on the drivers side, at the leaf spring just a bit-to be corrected. Thank you for helping me find the kink in the fuel line at the tank, nobody has ever caught it!
Hope this helps
