I have that setup on all of my D1/D2's.

Let me tell you, first and foremost, do NOT go flowmaster. The drone is worse than with straight pipes. I had the flowmaster 40 specifically, but even coupled with a resonator it was still colossal.

The single perforated core glasspack wasn't bad, but wasn't great. Drone wasn't terrible though.

By far my favorite has been my Borla Pro XS. It began with magnaflow cats and the single in dual out muffler which I have a clip of somewhere. I'll see if I can find it. The drone wasn't bad at all and had a nice rich tone. It has since morphed to long tube headers, no cats, 2.5" y-pipe, into the Borla, then 3" single out the back with not one, not two, but three resonators. Going catless makes this truck LOUD. That said, even without any of the resonators there was absolutely zero drone after I went to long tube headers.

Anyway, my final recommendation is the Borla Pro XS. I definitely recommend it going on out the back. That will further decrease cabin noise as opposed to a dump. Should be a simple cut out and weld in procedure for both the muffler and the resonator and you'll only need a couple lengths of 2.5" pipe which the exhaust shop will have in stock if you take it to a shop.

Edit: Here is the old video I had. The sound isn't great as it was recorded on a knock off go-pro, but still gives you somewhat of an idea.

They say they're for a RHD Range Rover Classic, but they were a perfect fit. Install them from the top with secondary air removed. It will still fit back after no problem. I would definitely have them ceramic coated also because they are pretty thin and rust pretty quickly.

I will say, if I could change one thing, it would be to replace the header ball and cup adapter with 2.5" v-band clamps. If I could change one other thing, I'd use catalytic converters. Probably a spun style. You don't see any gains from losing the cats, but in the US it's a $10,000 federal fine if you're caught without which can be administered from both a visual check and a smell check.

As for the resonator, when I had my stock setup I ran without. That said, the single in dual out muffler is a little longer than the single in single out, so it may be a hair louder than the single/dual and therefore you may prefer a resonator though I doubt it would be terribly loud without. I would probably run without the resonator, but that's just my personal preference. If you have the ability, I would try it without first and if you think it's a little loud then add one before you have it coated since that minute detail really comes down to personal preference.

I don't know about the exhaust Alex but I reckon your Watts linkage bushes are shot that or the shocker bushes. (I like quiet trucks, no noise, no roar, just sedate ;))
