Using your Remark axle back exhaust is straightforward. First, make sure you have all the included gaskets and bolts ready. You can directly bolt it onto the OEM or Remark mid Y - pipe, so installation is easy even if you're not a professional mechanic. When driving, you'll immediately notice the improved sound and performance. As for maintenance, regularly check the bolts to make sure they're tight. You can clean the stainless - steel parts with a mild stainless - steel cleaner to keep them looking shiny. Avoid using abrasive materials that could scratch the surface. If you live in an area with a lot of salt on the roads during winter, rinse the exhaust with water after driving to prevent corrosion. And that's all you need to do to keep your exhaust in great shape and enjoy its benefits for a long time.
