5 Reasons to buy SSR Performance downpipes

  • Every single set of downpipes is fitted to the same EXACT, proven, jig to guarantee, direct bolt-on, perfect fitment every time
  • SSR downpipes are crafted using ONLY certified 3 inch diameter 304 Stainless Steel and are TIG welded by our Certified Professional TIG Welder right here in Orange County, CA
  • Completely precision CNC machined mono-block lipless / stepless V-band flange design
  • Developed and flow tested by our engineers directly on our shop M3 and M4 to provide optimal flow and horsepower gains on the Dyno and on the Track
  • No Hassle LIFETIME warranty (see below for details)



We guarantee that any downpipe we ship will fit on any M3 / M4 perfectly. We create our downpipes using a fitment jig which precisely defines the pathways the downpipes follow down to the exact length and degrees of bend. SSR Performance downpipes are direct bolt-on replacements of your stock downpipes. Any hardware needed is included.


Build and Design

We craft all of our downpipes using only certified 304 Stainless Steel. We chose 304 Stainless Steel because of its weldable properties, high corrosion / oxidation resistance, and relatively high toughness. The process of building these downpipes begins with the in-house engineering design work on our own shop F80 M3 and F82 M4. It then moves onto the precision CNC machining of our V-bands, flanges, and O2 bungs. Lastly, it ends with the welding and beautiful line grain finish of the final product. This whole production process takes place in the USA and supports approximately 100 American jobs every single day.



We engineered our downpipes for optimal flow. We take pride in our education and do not hesitate to make it very clear that everything we create is designed and tested in CAD / CAM software much before it is ever fabricated into a real physical part. We have created a completely precision CNC machined mono-block V-band that is completely smooth and has no lip or step. We know how important it is for exhaust gases to pass through from the turbos to the exhaust smoothly, so we took initiative and designed our downpipes in such a way that flow is maximized.
