Description
Old School Sound. It's one of those modifications we dreamed about when we bought our Mustangs in the first place, right? That exotic beastly muscle car sound. This 3" Retro LMF Cat-Back Exhaust from Stainless Works features a classic X-Pipe design that not only makes the exhaust flow more smoothly and the engine run more efficiently, it gives that old school sound that we've loved since we were kids. SW didn't stop there, as they included two 3" core retro mufflers and two 3" core resonator tips with the sole goal of being especially loud. Designed to be used in combination with Stainless Works Long Tube Headers, your 2015-2017 GT will certainly be turning heads any where you go.
Smart Design. The engineers at Stainless Works built this system for improved sound and performance. Their clever design ditches the whisper quiet stock resonators and factory mufflers in favor of a complete X-Pipe assembly leading into two retro chambered 3" core LMF mufflers and resonator tips. The result? A seriously loud exhaust system not for the faint of heart (you can guess what LMF stands for). Stainless Works proudly manufactures and tests their products in the USA, so you can be assured of quality workmanship.
Better Steel. Made from high quality 304 stainless steel, this Stainless Works 3" Cat-Back with X-Pipe won't turn red with rust or corrode with the weather the way cheaper stainless steel does. This system features full 3" mandrel-bent tubing, giving your exhaust gasses a bigger, smoother outlet and increased performance. Not only will this exhaust system provide enhanced sound and power, it's finished off with two stunning mirror polished SS slash cut conical double-wall tips.
Application. This Stainless Works 3" Retro LMF Cat-Back Exhaust System is a perfect upgrade for 2015-2017 Mustang GT Fastbacks with either automatic or manual transmissions. Requires Stainless Works Long Tube Headers for proper fitment - please see ordering options above. Not compatible with convertibles.
