I just recently got myself a 1974 Plymouth Barracuda thats in great condition. It's a 318ci V8, but its got a 4 barrel instead of the stock 2 barrel that came with the 318ci. The engine was built in PA by a guy who specialized in racing engines.

The only issue I have with the car is that it still has stock mufflers on it. It's got the dual exhaust, but I think a new set of mufflers would really make the exhaust tone hellish. It's good and loud now, but there's room to improve.

I'm thinking something from Spintech or Flowmaster, but I'm not all too familiar with the fitting types of the older cars.

I have a 2001 mustang with a pair of Spintechs.

Anyone have any suggestions where to look for some advice?
