Comparison
Compared With The Alternatives
| Factory exhaust system | The stock exhaust is designed for emissions compliance and noise reduction, this one increases flow and engine breathing at the cost of a louder exhaust note |
|---|---|
| Mild steel aftermarket exhaust | Mild steel is cheaper but rusts through at the muffler and flange joints within a few years; T-304 stainless holds up through long-term exposure to moisture and heat |
| Universal cut-to-fit exhaust | A universal pipe requires cutting, welding, and custom fitting, which increases labour cost and risk of leaks; this one bolts on directly |
Installation
Use Guide
- Confirm the vehicle is a 1989-1997 Mazda Miata MX-5 or Eunos with 1.6L or 1.8L engine
- Disconnect the battery before starting exhaust removal to prevent electrical issues
- Remove the factory exhaust from the catalytic converter rearward, including the muffler and tailpipe
- Install the new catback system using the included bolts and gaskets, torquing in a crisscross pattern
- Recheck all flange connections after the first heat cycle to ensure no leaks
