looking to trade my shorty Prochamber for a shortly X-pipe, Prochamber will fit 99-04 Mustangs w/ long tubes. i just want my car louder, the prochamber offers GREAT power gains but it si just not my cup of tea in the sound department. anyways, i will provide all the supplies and garage nessicary to do the swap and will even put in all thw wrench time to make the trader completely at no loss for this trade. all you will have to do it show up and sit back and then go on yourt way with a new Prochamber under your car. Prochamber has about 1k miles on it and if the catless version. X-pipe needs to fit my 2003 GT 5-speed and must be in decent condition.
