Muffler

Any 4 or 6 cylinder engine will sound horrible with anykind aftermarket exhaust when it has no cat converters on it. Start with having those put back on, and then you can use most mufflers to fit your liking. Exhaust pipe size and location has alot to do with also. The engines health also involves exhaust note and tone.

Those 94 4.0 engines sound good with flowmaster...personally my choice would be, get cat converters back on there and use 2.5" piping routed like the stock exhaust is, use either a flowmaster original 40 or flowmaster deltaflow 40...use a single in and single out mufflers. With either of those mufflers it will sound, even 2.25" piping will make that 4.0 sound good. Its a simple system that will look and sound good.

I used am old flow master that was in the garahe from a previous v8 truck on my 04 v6 ranger and it actually turned out great. It was a single in, dual outlet model and I just had the tips ran out in front of the passenger wheel. It sounded nice and quiet at idle and then deeper when revving.

I was surprised it came out so good

If you don't act surprised when things you do come out well people will just thing you're good at it.

I had a 2 1/2" single exhaust on an 81 Cougar that I transplanted the old engine from my Mustang into a few years ago. It had a 50 series Flowmaster with a short glasspack behind it to kill the typical Flowmaster hollow tin can sound. When the glasspack got rusty I put a Dynomax Super Turbo in place of the Flowmaster. I owned the Super Turbo and would have had to buy a new glasspack.
I bought a new 77 Mustang with a 2.8 and a 4 speed, a friend liked it so he bought one, too. He had a muffler shop make a dual exhaust system with glasspacks and it sounded somewhere between a weed whacker and a snowmobile.
