I donno, when looking at exhaust I always just recomend custom... price is ALWAYS comparable and the work is 100% better and always guarenteed...
There is an exhaust shop down the road from us, they do fantastic work, Martin had his Del Sol done there... they will price match any written estimate as far as i know and they do all their own bending.

I would go by their shop, tell them Colin from Carriage sent you for an estimate and what you were thinking about doing.
