The Turbo XS Standard Rear Muffler features full stainless steel construction, 3" diameter piping, and a 3.5" polished tip. The tone is not too loud for those who are looking for a mildly aggressive tone for their daily. The Turbo XS rear muffler assembly will bolt to a stock midpipe for a little more sound, or will bolt directly to the Turbo XS midpipe.
