We are running through exhaust testing on our 2025 Low Rider S and the next pipe we have in our line up is the Trask Assault 2-1. This pipe is designed to improve exhaust flow and deliver a deep, performance oriented exhaust tone. It is a direct replacement for the stock exhaust and includes heat shields. 

This pipe comes in four different finish options so depending on the style of your bike, you can choose Stainless, Polished, Black or Black with Stainless Shields. 

Currently our Low Rider S has the Star Racing M28 cam paired with the HPI throttle body and Air Cleaner. We also used the ThunderMax ECM to tune it. We like using this ECM to get bikes running right, it utilizes wide-band oxygen sensors and works as a closed-loop control system to continuously self-adjust and properly tune the motorcycle’s air/fuel ratio.

After getting the bike dialed in, we ran it on the Dyno. Our final SAE numbers came out to 132 HP / 135TQ with a nice curve to go with it. 

You can check out our Youtube video for a more complete sound check on this bike. Or click the image below to watch it on Youtube. 

Overall, we're really happy with how this exhaust performed with the M28 cam and HPI air cleaner combo. It's a clean looking, solid performing exhaust that delivers on style and power. 

We will be releasing more exhaust comparisons over the next couple of weeks. If you have any questions, please feel free to hit us up cs@getlowered.com or 215-394-8409.
