Hi,
Mopar Performance has, or at least used to have, '91-only Dakota 318
headers available, and I'm sure you can get a good catback from just about
anybody. When we replaced the engine on my little brother's '91, we kept the
manifolds and had a local exhaust shop install a hi-flow cat and flowmaster
with dual tailpipes. Sounds good and no problems. Cheaper than a cat-back,
too if I remember. This may be the way to go since you have a gutted cat.
