Description

We utilize the best processes and source components from top North American suppliers for Tapout downpipes. Constructed from real, high grade 304 stainless steel, we are so confident in our quality that we are offering a twelve-month warranty against cracks and failures.

Fitment is as good as OEM, whether you have an A8 or M6 transmission. These downpipes do not make contact with your transmission or cooling lines. The crossover/balance pipe is located higher than on other brands, slotting it nicely between the wiring harness on the engine block and the transmission cooler line. All four oxygen sensor bungs are correctly located, so your wires do not need to be stretched or extended. Our design also provides the same ground clearance as stock, and there won’t be issues even if you lower your car.

Thanks to dual expansion chamber resonators or catalytic converters (depending on the option you select) and full two inch crossover/balance pipe, these downpipes will sound great, regardless of how the rest of your exhaust system is configured. There is no rasp or drone. Instead of using a double slip fit crossover that’s prone to leaking, we include a proper band clamp for complete sealing. OEM catalytic converters weigh 23 pounds. Our catless downpipes reduce this by nearly 50% to only 12 pounds.

Each Tapout Downpipes purchase order comes with a FREE update to your Tapout Tune. We will disable Catalyst Warmup, Catalyst Overtemp, Catalyst Test and all 36 DTCs related to the catalytic converters. Just let us know once you have your Tapout Downpipes installed and we will be happy to provide you an updated tune!

Tapout Catless Downpipes under WOT acceleration

Our downpipes have absolutely zero obnoxious drone or rasp. Driving leisurely in Touring mode, you won’t hear any difference compared to OEM. At full throttle, you’ll be treated to an aggressive stereo symphony. This video was taken on a 2016 ATS-V with Tapout Catless downpipes, and otherwise completely stock exhaust.

Tapout Downpipes PTM Launch

Tapout Catless Downpipes on startup and revving in Park

At startup and idle our catless downpipes sound similar to stock, just a little louder and more crisp.  When you rev the engine you’ll be treated to louder turbo spool and a sinister growl.

Catless downpipes do not meet emissions requirements and are intended for off road use only.

Non-EPA catted downpipes utilize ultra-high quality and high performance catalytic converters, that balance exhaust flow with effective emissions conversion, and are also for off road use only.

The EPA Catted Downpipes are legal for all states that don’t have CARB regulations.

None of our downpipes are available for sale, shipment to or use in California.
