I'm wanting to get the full roush body kit for my 00 mustang gt. I want the side exhaust but I dont wanna spend 800+ dollars for the roush one since its basically just the mufflers, a couple pipes and exhaust tips. Could i go to a muffler shop and have them make me like 2 curved pipes to go from my exisiting mufflers and then just get the roush exhaust tips? Figure that would be a lot cheaper if its possible.
