The downpipes are handmade in Taiwan. The tubing, flange and hangers are made from 304 stainless steel with a brushed matte finish. we use a 2.5" tube which mates up to the factory 2.5” down pipe, then to the factory 2.25" exhaust. The flanges are 0.25 inch 304 stainless steel and were CAD designed to match factory specs and are precision cut with a 55,000 PSI water jet. The entire downpipe is purge tig welded. We incorporate stainless steel flex braid exhaust tubing, which is similar in design to the factory setup.

The Thunder's NEW CAMRY 3.0 Down Pipes are one of the easiest ways to unlock restricted horsepower from your turbo engine. It has been designed to allow maximum flow exiting the exhaust side of the turbo.

The Thunder's NEW CAMRY 3.0 Down Pipes have a enlarged pipe diameter in order to allow gasses leaving the turbo to flow at a more rapid rate than the restrictive OEM down pipe. This improved exhaust flow will result in more horsepower and torque by allowing the turbo to spool quicker and stronger. This also allows the turbo to work more efficiently with full boost being achieved lower in the RPM curve than before.

Made from high quality stainless steel to resist corrosion and mandrel bent to ensure a smooth flowing surface, the Thunder's NEW CAMRY 3.0 Down Pipes will bolt directly to the OEM turbo using existing hardware for a factory-like fit. The down pipe incorporates bungs for existing OEM sensors to retain proper engine management.

The Thunder BMW E36 Exhaust Headers have been designed to improve exhaust flow leaving the cylinder head with fewer restrictions.

This 6-2 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 BMW E36 M3 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 BMW E92 - M3. The Large-caliber pipes allow exhaust to flow more freely through the entire system. This free flowing exhaust is what allows your BMW E92 - M3 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.

Thunder has developed and tested this exhaust system for the BMW E92 - M3. The all SUS304 stainless steel exhaust features a polished finished, thick flanges, OEM fit, and an incredible sound. but had great performance gains on the street. With the competition being tested, Thunder exhaust features extreme quality and fitment. The full stainless muffler system is completely polished. It fits to your stock exhaust hangers and fits with the stock or aftermarket pipes using the same flange connection. Features large diameter, mandrel-bent extensions and tailpipes that are stainless steel and feature a polished stainless steel tip. System includes the Magnaflow Performance Muffler best suited to the needs of the vehicle and all the system hardware, flanges and gaskets needed to complete the installation.
