Product Description

FOURTH GENERATION UPDATE....A revolution in exhaust technology finally available for all MX5 NB 1999 through 2005 MX5's

Our new HELMHOLTZ exhaust system features an exclusive Helmholz main chamber that massively reduces the standing wave 'boominess' 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.

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.
