I know what you are trying to do, and I've been down that road on an H-body monza. I can tell you what I did, if you want a transverse muffler it's probably your only option.
The H-body Monza's share the same chassis design as the 3rd and 4th gen Fbodies, just on a smaller scale. They were the predecessor to this platform.
I wanted true duals on mine, over the axle and out the back. These cars also used a transverse muffler in the rear, but the problem was,,,,No one on the planet even made an exhaust kit for these cars of any kind in any form,,,,,period. So no matter what I did it would have to be custom.
I first took measurements in the muffler location to get an idea what would fit. Then I sat down with Flowmasters master catalog that lists every muffler they made complete with dimensions. At the time Flowmaster had the largest supply of aftermarket mufflers in various shapes and forms for just about every application.
I found a muffler they made for a small SUV that fit my dimensions as well as the pipe sizing I was going to use. The muffler alone was $120, this was 7-8 years ago.
Bought the muffler and took the car to a local shop who was a very good friend of mine, I knew I could work with him. I showed him what I needed, how I wanted it routed and so forth. No easy task to run dual pipes over the axle on a monza that is half the size of a 4th gen if you can imagine. Probably very hard nowadays to find a shop that would even touch it.
In the end I think I spent ~$600 for the setup, and we are talking 7-8 years ago for crushed bends and aluminized piping. But it was unique and the only true dual H-body setup I was aware of,,,,hell the only H-body still on the road for that matter :chuckles:
In all seriousness, finding a transverse muffler to do what you want would be easier now since alot of other companies have stepped up with this design since I fooled with it. Or you could always run a pair of small (in/out) mufflers on either side of the car just behind the rear bumper, and you should have enough room to squeeze tailpipes on it.
My honest opinion though, if you don't want to coin up for a good dual exhaust system and want something cheaper. I'd do a 4" single Mufflex system. We ran a dozen 3" catbacks on a very stout 4th gen several years back and found the Mufflex 4" system outperformed them all, sounded mean, relatively cheap and good fitment.
I never got the chance to compare it to the Bassani true dual system, quite frankly it was more than I wanted to spend for a simple test, and there weren't many out there at the time that I could borrow.
In any event, If I were building a max effort 4th gen and wanted a nice system that went over the axle, I'd probably go straight for a Mufflex 4" system. They also make this system in a 3 1/2" setup. They have a wider choice of mufflers too since I last used them.
If your heart is set on a real dual system, then in my opinion, Bassani is the way to go. It's nice that someone else stepped up to the plate with a similar setup (Kooks) but the price is a big turnoff.
