not familiar with the kit, but, any exhaust that fits well shouldn't be more than about $100 to install, and personally I would go with clamps over weld. Almost every welded install I have seen rots off prematurely. I think the extreme heat effects the anti corrosion coatings on the metal and causes them to rust out early. With clamps, no heat or chemical reactions to cause problems. I know welds done properly don't usually leak, but I have been in the auto repair business for 25 years, and have seen very few issues with properly sized clamps leaking either. Just my unsolicited $.02 worth. Enjoy your new pipes however you have them put on, should sound great.
