3 inch stainless mandrel-bent cat-back system is vehicle-specific; bolts-on easily. Monster muffler improves flow up to 211%. Throaty sound; 4 inch polished tip. Banks' popular 100% stainless steel cat-back Monster exhaust system for FJ's is vehicle-specific for fast bolt-on installation. No welding. No cutting. And virtually no backpressure, either! The 3 inch mandrel-bent pipes and the straight-through polished-stainless Monster muffler work together to dramatically improve flow (Monster muffler alone improves flow a whopping 211%!), allowing the FJ engine to deliver more power with less work. Banks' Monster exhaust is designed and sound-tested to dissipate that irritating interior resonance that plagues most straight-through muffler designs. The sound is rich and throaty without being too aggressive. For an eye-catching finish, Monster flashes a stainless 4 inch dual-wall rolled-edge angle-cut tailpipe tip in your choice of polished chrome-over stainless or high-temp black! Banks' Monster exhaust system is vehicle-specific for bolt-on installation. Please note: The tip exits to the rear, not from the side factory location. New options! The Banks FJ exhaust is now available with two different tip options: ob-round (3.5 inch x and 6 inch x 4 inch out) or round (3 inch in and 4 inch out). JUST ADDED! Now you have FOUR tips from which to choose...you can get the ob-round or round tip in polished chrome--or you can get it in high-temp black!
