Thunder's Exhuast headers are one of the best performance upgrades available for any application. Mandrel bent stainless steel to provides the best flow and durability, 12mm-thick flanges with oversized for exhaust ports and machined sealing beads for better flow with no leaks. Thunder's headers are significantly less restrictive than the stock manifolds on a vehicle and dramatically increase the power and efficiency of an engine. With durable stainless steel construction that can survive the abuse of racing, towing, and daily driving, these headers can take a beating. Each system includes high quality hardware and thorough instructions for a professional no-leak installation.

The Thunder MAZDA 3 - 2.0 Exhaust Header has been designed to improve exhaust flow leaving the cylinder head with fewer restrictions.

This 4-2-1 exhaust header achieves this better flow by increasing the size of the header piping and removing the power-robbing catalytic converter. This increased flowing ability results in more horsepower and torque that the engine can produce. Throttle response is also improved at all RPM ranges.

Each header is made from high quality stainless steel and is mandrel bent to reduce exhaust obstruction. The MAZDA 3 - 2.0 Exhaust Header bolts perfectly to the cylinder head using existing hardware and includes bungs for existing OEM sensors. The exhaust header will bolt to your existing factory exhaust or other aftermarket exhaust system for an OEM-like fitment.

The Thunder's mid pipe is a great exhaust upgrade for the CIVIC - 8th 1.8. The Large-caliber pipes allow exhaust to flow more freely through the entire system. This free flowing exhaust is what allows your CIVIC - 8th 1.8 to produce more power. The mid Y pipe upgrade can be used with a stock system or with the aftermarket options available today.
The all SUS304 stainless steel pipes feature TIG welding, thick flanges, 02 Bungs, gaskets, and a complete polished finish.
These pipes in conjunction with our Thunder's muffler and headers will yield an amazing gain.
