FOURTH GENERATION UPDATE....The Helmholtz chamber revolution in exhaust technology finally available for all MX5s! Our new HELMHOLTZ exhaust system features an exclusive Helmholtz main chamber that massively reduces the standing wave 'boominess' or drone inside the exhaust system! Cuts the 'booming' frequencies of 120-130hz by over 35+db inside a top up MX5 cabin which is a common source of complaints with aftermarket exhausts on the MX5. Result is all the FUN throaty sounds you want, without the drone other systems make that wears you out on long uphill and downhill sections of road.
Updated version of our favorite NB Muffler, now the ONLY choice on the market with Helmholtz chamber...AND adjustable sound level! YES, fits manual and automatic transmission. Built in solid 304 stainless steel and completely polished to a mirror finish, this high quality MX5 exhaust is our only choice that incorporates a baffle insert that gives YOU some control over the final sound level (baffle in is only about 15% more sound than stock, baffle out is about 25% more sound than stock...so you always have a choice for those longer trips). Weight is lighter than factory.
For those that want even more sound add our highflow MX5 midpipe for more flow and another 10% more sound.
This latest version of our best selling MX5 exhaust has both baffle included and a double walled tip for years of lasting good looks while giving you control over the final sound level. And, you always have the option of our packed baffles which are sold here separately.
BRIAN'S APPLICATION NOTES: This is an AGGRESSIVE exhaust at full throttle! The Helmholtz addition does not make it quiet, quite the opposite, it allows almost a straight pipe full flow design with good control over drone when just cruising so we can let all the fun sounds out at full throttle. The Helmholtz chamber knocks down what most of us perceive as drone by over 35 db but it lets all the rest of the upper frequency fun and pops and burbles right on through! That means by definition this muffler is aggressive, has a ton of attitude on an otherwise stock MX5, and is NOT for everyone! Given that this muffler is aggressive on otherwise stock MX5, it will be really loud, race track loud, if you add header and highflow cat. Designed for the three pedal owners out there who love to zing these amazing sportscars to redline daily.
