Is this Marketplace dual exhaust more trouble than it's worth?

When I swap in my Buick 350 I'm going to upgrade from single to dual exhaust. I found this full system semi-local. I know this won't bolt up to the Buick manifolds & I thought about having it modified to mate up with the TA Buick 350 downpipes. But I feel like the front half of this system isn't really suited to that because of everything being kicked to the passenger side. Am I right... is this "too far off" to be worth it? It's tempting because the TA kit is $435 less mufflers.

Any competent exhaust shop would be able to graft new down pipes into the existing system configuration to match up to a Buick engine.
The system is bent the way it is to make use of the factory single hump trans crossmember instead of using an aftermarket dual hump or modified stock one.

I usually pass on jury-rigging, especially, when it involves too many issues. I try to do it right the first time so as to NOT have regrets later on. Check out a Pypes kit that would also include either a cross-over or H-pipe. Just so you know, there will be an additional cost for a proper transmission cross member.

Pypes is currently only selling (from my last check of their site a few months back) OE type 2.5" cat back, 2.5" X pipe duals with cats ($$$, per a EPA threat) & 3" X pipe duals w/o cats as a racing kit.

I don't like that it has rear exit tail pipes.
I would buy the mufflers that you want and maybe some tail pipes from this place:
and build your own to connect between the mufflers and downpipes or maybe take it to an exhaust shop and have it done
