H/C/I low Dyno Numbers??
Anyway, when you can, put a 3" or 3.5" mid pipe to a same-size muffler and tailpipe. While not totally optimum, it would be a huge improvement over what you have, and will make the power a lot closer to your original expectations.

The Best V8 Stories One Small Block at Time
for those that dont know the place he took his car CAM Carolina Auto Masters is filled with a bunch of idiots and i dont understand how this place is still in business.
if you ever hear anyone saying their gonna use that shop please steer them clear of those retards. Way to many horror stories I've heard and read about that place
Having a pair of cut outs added directly off of the header is inexpensive. For track or dyno uncap the cut-outs. Electric is nice but manual is less expensive.
My RS had a similar exhaust issue because the shop notched the Y pipe collector to fit a certain type of subframe connector. At the end of the project money was very tight. Replacing the exhaust etc wasn't an option. The twin cutouts were worth 20 whp on the dyno. The gains were from the start of the dyno pull to the end. Gained every where. Torque also increased for the whole dyno pull. Way to loud uncapped for the street, basically like open headers.
A friend gained ~30+ hp with a similar set up. He had a stock I pipe /mid-life and cat back. With your current set up I would expect 20 to 30 whp.
If you want twin electric cuts off of the headers are an option with a lot of flexibility but more expensive.
Personal experience -- Mamo 220 heads, arguably the best available for a 5.7, 227/235 cam, 1-7/8 headers, 3 inch Y and cat back, all kinds of optimization. 395 rwhp. Talk about PISSED. Tuner exact words -- something is wrong with your exhaust.
With open headers, 470. Add X pipe, 3 inch true dual, light clutch, 496.
Yes duals are expensive, but cheaper than buying a cheap exhaust and THEN duals. Believe it or not we are trying to SAVE you money.
