Using this ISR Performance turbine extension is straightforward. First, make sure you have all the necessary tools and parts. You'll need to reuse your OEM turbine housing studs and nuts. Install the gaskets and hardware that come with the product. When putting it in place, be aware that because of its larger 3 - inch diameter, you might need to clear some space around the bellhousing or flange. This could involve a little bit of adjustment. As for maintenance, keep an eye on the double - welded areas. Check for any signs of cracking over time. The brushed finish gives it a nice look, but you can clean it gently with a soft cloth to keep it looking good. If you notice any issues with the exhaust flow or if there are strange noises, it's a good idea to inspect the extension right away.
