Rogue Engineering is proud to introduce our MZ4 Midpipe . A cursory glance at the exhaust easily shows how this exhaust excels in both performance while saving weight. However, a closer look will show the pure artistry of its construction and elements of unique design.
A very unique exhaust for a very unique vehicle
Like the successful E46 M3 exhaust products, the MZ4 midpipe is designed to compliment the high-revving engine concept which BMW has implemented into these M brand vehicles. This means that the exhaust note will not only sound good at low RPMs, but also at the high RPM limit of the engine. By eliminating the monitored catalytic converters, you get more power!
It's not like Rogue Engineering to rest on its laurels when it comes to development of any performance product. In fact, we are typically the first to market of product in many instances. However, when it came to the MZ4 exhaust, we were definitely NOT the first ones on the block. By last count, there were at least 4-5 different exhaust for the MZ4.
The Rogue Engineering E85 MZ4 Midpipe replaces the stock BMW rear mufflers (shown in blue) using all factory mounting points.
MZ4 Midpipe Features
The RE Midpipe is made to fit in the factory position. Features include:
- 100% T-304 stainless steel construction and internals
- Fully mandrel bent tubing, no crimps or flattened areas
- Eliminates factory unmonitored catalytic converters, increasing power and sound. Will NOT set off check engine lamp on the dash! Check with your local laws regarding removing factory emissions related parts.
- No permanent modifications required for installation
Compliment this item with optional E85 X-Pipe and MZ4 Diablo Exhaust.
All Stainless Steel is the same, right? WRONG!
All Rogue Engineering Diablo exhaust are produced using only 100% full T-304 stainless steel because of its consistent strength characteristics, corrosion resistance, and wide range of materials (important for controlling sound and exhaust flow).
Beware of some companies that pre-coat their exhaust products with "thermal coatings". In fact, they may be hiding inferior stainless steel or inferior welding processes. Rogue Engineering Diablo exhausts are always TIG welded and never coated.
Some companies have chosen to build their "stainless steel" exhausts with Grade 409 stainless, because it is less expensive than 304. While Grade 409 will resist atmospheric and exhaust gas corrosion, a light surface rust will form is most all atmospheres.
Installation Notes
Installation of the MZ4 Midpipes requires no cutting or welding. Installation time is approximately 1 hour. No new gaskets or hardware are required.
