Using your Invidia Q300 Cat Back Exhaust is easy. First, make sure your vehicle is parked on a flat surface and the engine is cool. If you're installing it yourself, follow the included instructions carefully. Connect the exhaust to the existing system using the provided gaskets and hardware. The exhaust hangers are already welded at the right spots, so it should fit directly. When it comes to maintenance, regularly check the gaskets and hardware for any signs of wear or looseness. Tighten them if needed. You can clean the stainless - steel parts with a mild soap and water solution to keep it looking good. If you have the factory downpipe, don't forget to use the adapter for a proper fit. Enjoy the great sound and performance this exhaust brings to your Subaru!
