iND | AMS Alpha Downpipe set



The Alpha S63TU Downpipes are the ultimate solution for improving power, throttle response and exhaust note without sacrificing quality, fitment or design.

Each Alpha S63tu Downpipe set features a smooth transition from their massive 3.5 inlet down to the 3 tubing for optimum flow. While the competition chose a very short transition length which creates turbulence and hurts exhaust flow and power, the AMS Engineering team implemented a longer length to give the S63tu maximum output.

The AMS Alpha downpipes are properly designed and engineered utilizing a CMM Laser Scanner for a perfect fit as well as space optimization. The factory O2 sensors, heat shielding and brackets where integrated for a OEM fit and finish.

The Alpha HFC downpipes are equipped with 300 cpsi catalysts. Many competitors offer a low quality converter option to keep the cost low and profits high. Often these units fail due to poor construction and inferior materials. When you choose Alpha you will remain emissions compliant and worry free for years to come.
  • Compatible with M5, M6, and M6GC
  • 100% 304 stainless steel construction
  • .065" thick tubing
  • 300 cell race catalytic converter (optional)
  • Ceramic coating available upon request

Please contact a IND representative if you have any further questions or inquiries.

The downpipes are available for purchase through the IND website or directly with a IND representative.

Do you have any performance data (before and after) for these downpipes?

Currently the only option is to wait for a proper tune. We are also exploring various hardware alternatives.

Pm if you have any further questions.

A fix like Burger tuning for the N54 would be great for those not interested in a tune.
