Product Information

Part #: IS-O2-SR3IN. ISR Performance presents the first genuine 3-inch turbo outlet. Unlike other turbine outlets that narrow down, this new design from ISR (formerly ISIS) offers a higher-flowing, true 3-inch outlet. Turbo outlets boost exhaust flow and increase horsepower, making it a cost - effective upgrade. It comes with all the gaskets and hardware needed for installation, though you'll need to reuse your OEM turbine housing studs and nuts. This particular outlet has been double - welded inside and out to prevent cracking. Due to its larger 3 - inch diameter, it may require a bit of clearance for the bellhousing or flange. It has a brand - new brushed finish. Specs: 3 - bolt flange thread pitch is M10 X1.5, and the bolt length is 1 3/4 inches.





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.
