Magnaflow Catback exhaust kit is made with 2.5" stainless steel and sounds throaty yet quiet. The kit fits your 86' Mustang Gt and 87-93 LX Mustangs with a V-8. The system provides a huge power increase and decrease in backpressure. This is a bolt on kit. If you can use a hacksaw and turn a few wrenches, you can install this system. Free Shipping on this item
