Great muffler! Combined with an 18" Magnaflow resonator and a powerful Vibrant catalyst on my 1998 Integra. It replaced a JDM B18 Type-R engine and sounds great! has a nice little rumble when the car starts and almost standard noise at idle. The exhaust is fairly quiet at 5000 rpm and opens when VTEC kicks in at 5800. Magnaflow may not be your first choice, but their products will give your engine an L4 stylish sound!
