Using this Tomei exhaust is a breeze. First, gather all the included gaskets, hardware, and the silencer. Then, carefully install the exhaust system following the standard installation procedures. If your car has the factory downpipe/J pipe, remember to get an adapter from GrimmSpeed before installation. As for maintenance, regularly check the connections to make sure they're tight. You can clean the exhaust with a mild automotive cleaner to keep it looking good. Avoid using harsh chemicals as they might damage the titanium. And always start the car and listen for any unusual noises after installation or maintenance to ensure everything is working properly.
