Fabricated right here in the U.S. of A, our muffler delete pipe is made of mandrel-bent and TIG-welded stainless steel. It bolts up to your exhaust exhaust system, completely replacing the heavy stock muffler. The amazing thing is that it isn't that loud, and sounds great. Don't believe us? Check out the video. We admit, this item alone is not going to increase horsepower (we tested it), but your car WILL lose weight, and lot of it! The factory muffler weighs 26.0 pounds. Our muffler delete weighs 2.95 pounds, so you save a whopping 23.1 pounds. Attaches using your existing exhaust hanger and gasket. (If you've lost your stock gasket, we also sell those, below.) Fits all 2013+ BRZ and FR-S. Now in stock!
