CSP - seem to fit the best, but still have issues with the wiring harness having to be moved. Never in stock and $1600 with off-road connection pipes
Kooks - cause false knock, wiring needs to be moved, rubs motor mounts, have to drop starter and sits very close to the starter. Can buy CSPs clone version with connection pipes for $1350
ARH - had arh on my old car, had burnt wires. Price lol
TSP - fit issues with steering column. Some have to dent the headers or just have it rub the steering column. Also no rear 02 bung on the cats, so no putting wideband. Not sure if the high flow cats are good, not sure if the my are 200 or 400 cell. Very reasonable price 1k with cats.
Speed engineering - fit issues, clamps leak, cheaper metal, not cat options but damn cheap and since the all have problems why not. Very feasible price $750 ish with 3” x pipe going to axle back.
Stock manifolds - give up on 10-20 rwhp on a bolt on car, no cool exhaust noise but no cost and problems.
I’ve search many times just wanted some fresh opinions.

I've installed just about half a dozen sets on both ZL1's and SS's and I've never had any problems with any of those brands. A majority of the cars I've done have been speed engineering. Never any fitment issues, clamps work as expected. I personally have them on my car as well, I was able to get them for 400 bucks brand new off Facebook. Couldn't turn that down...
