Accurate Exhaust has both single and dual exhaust systems for the 318.  You need to give them the part #'s of your exhaust manifolds when ordering.  If you have headers on the car, you'll need to look into another company.

My Accurate system is 2" off the manifolds and expands to 2 1/4" the rest of the way back.

I would use dual , 2" should be lots on a 318 , mufflers can be anything depending what sound you like .

I have a muffler shop 2 1/4" dual exhaust with what looks like flowmaster welded aluminum mufflers on my 73 318 Barracuda.  Sounds great for a basically stock motor.  If I build up the 318 or swap in a 340 I 'may' put headers on it, but I really like the mellower sound and stock look on this car.  I have heard a lot of good things about accurate exhaust if you're keeping yours stock appearing, otherwise I'd also check out systems from TTI, magnaflow, etc.

Right now I have Doug's Headers and Summit 2.5" exhaust.  Sounds good, but need more engine  :burnout:

On my 340 I have Dougs headers and linked them to a 2-1/2" Xpipe Pypes stainless with their streetpro muffs. Took a little tweaking to get the tails centered on the tips. Looks good and sounds pretty mean.
