Exhaust system quotes

The Scamp needs a new dual exhaust system so I got a couple of quotes and am wondering if they are reasonable based on what others north of the 49th have paid.

It's a near stock 318 with stock manifolds and duals (1 7/8" dual set-up now) with no cross pipe now. I'm thinking of going with a 2.25" set-up

I got a quote from Shop A for a mandrel bent 2.5" exhaust for $850 installed (new from the bottom of the manifold back with H pipe). The place doesn't mandrel bend 2.25" pipe.

The second place doesn't mandrel bend exhausts but gave me a quote of ~$550 for a 2.25" exhaust from the bottom of the manifold back with H pipe.

I'd supply either shop with the mufflers and exhaust tips for install.
