Puch DOS Circuit Exhaust 31 5098 This pipe comes with 2All the blasty performance of a Proma Circuit but at an even more affordable price. This is the most commonly used pipe for Puch here in Atlanta. Excellent choice for stock or kitted bikes. Its a perfect first upgrade if you're still riding a stock bike and think you might want to add a cylinder kit later. Designed for Puch Maxi and similar models. If you have a stock Magnum, you'll have to modify your header and make a simple bracket for the rear.
