Our new X-pipe/resonator delete for the M139 (2003-2012). This pipe is made from custom-mandrel-bent 2.5" 304SS tube, is fully TIG-welded and features an authentic X-crossover design. The ends are sized to slip-fit with the factory cat pipes and rear exhaust section reusing the factory sleeve clamps. Provides a nice Euro sound, a little louder than factory. If you have already gutted your factory mufflers, this cost-effective part provides more of an open sound without the expense of a full exhaust.
