Try out Autoworks Service Center on Snead Ave. in Colonial Heights.

I've been there for a few things, really nice family owned business. The prices aren't the cheapest - but they're good and the service reflects the price. I know they do a lot of custom exhaust with tuner and muscle cars. Go check 'em out sometime, get a quote, and let me know what they say.

On Temple Avenue facing the Boulevard, take a left onto Snead Avenue going behind the Long John Silvers, etc. and go down a few hundred feet and you can't miss it on your right.
