My personal thoughts...exhaust kits do NOT save you money or anything in any way or form. In town here you can get true duals 2.5" pipe w/ 40 series flowdaddies out the tail w/ tips for like 200-250. I wouldnt even buy an actual kit from anyone. Glasspacks are another really really cheap alternative. But I'd get some good mufflers even if they cost abit more usually the gains are worth it.
