Bad product! I've had to replace them three times in the last two years. Now the problem has occurred again. After the pipes warmed up to operating temperature, and water got on the highway while driving, the pipe was subjected to very heavy loads, and "attention" these mufflers do not fit directly! You need to replace the intermediate pipe. Back to the question here! The baffles in the muffler do not withstand sudden changes in temperature and destroy the welds in the muffler. For now I will try to "re" contact a Walker representative to see if there is a solution! Let's see how long it lasts! Like a master engineer. I was very disappointed in the quality of the product. This product has the name of the hikers on it. They used to be considered a good aftermarket product!
