MagnaFlow Sys CB 99-05 Mazda Miata Fits select: 1999-2003 MAZDA MX-5 MIATA, 2004-2005 MAZDA MX-5 MIATA BASE/LS

I've had this magnaflow installed on my nb1 for the past 4 years. Still looks new. Still sounds great. When the muffler is brand new it's a bit quieter than anticipated but it breaks in over the first 500 miles and the sound settles into a nice deep tone. Very quiet at cruising and light throttle. Really wakes up under wot. When the car is cold, first start off the day, it does sound a bit raspy until it warms up after a couple minutes of driving. Definitely the best sounding NB miata exhaust I've heard in 25 years of racing these.
