These systems use Performance Flowmaster Mufflers. Even though they do not use original style mufflers, all of the correct brackets have been welded on the system. This allows the use of original style hanger kits for a clean and excellent "factory" fit. Much nicer than a "universal" system. Tips required and sold separately. To listen to a Flowmaster muffler, go to http://www.flowmastermufflers.com/40_delta.html and click on "sound clip in LH middle of page. Use EH-83 Exhaust Hanger Kit with this system.
