AVOTurboworld's Gen 3 Twin Muffler System for the 2008-2013 Exiga Wagon offers improved flow and a deep, smooth sound. The twin mufflers are constructed fully of stainless steel with 63mm (2 1/2) piping from the y-pipe section. The 4" single exhaust tips finish off the rear of the vehicle and fits well into the middle of the rear bumper cutouts. The tips are adjustable so that you can customise how far you want the tip sitting inward or outward. These are very high-quality pieces, perfect for that classy look and enhances the boxer burble while improving performance thanks to the freer flow.
