I installed one here in Canada I currently work at a gm dealer. We charged 15 hours including A catback and headers @ 112.00 per hour plus parts. Cheaper than A local performance shop. As far as warranty coverage your dealer will be more inclined to help you when you need warranty if you bring him some customer pay work and dont just farm it all out to other shops.
