About this part

Pipe Overview:

Hot Racing Losi Promoto-MX 1/4 Aluminum "Titanium Look" RCT Pipe. This optional exhaust pipe is intended as an upgrade for the Losi Promoto-MX 1/4 Dirt Bike. Made from high-quality aluminum using Resonance Chamber Technology (RCT), this pipe uses a patented core shape that lowers decibels while maintaining maximum power output. The titanium look adds a touch of realism to your motorcycle, while the aluminum construction maintains a lightweight profile. The pipe is heat-treated to ensure optimal performance during intense speed runs and high-performance situations. Heat treatment increases temperature resistance while providing additional surface hardness for exceptional strength you can rely on.

  • Made from high-quality aluminum
  • Patented RCT core shape lowers decibels without reducing performance
  • Heat treated to ensure durability and high-temperature resistance
  • Replicates a full size motorcycle exhaust
  • Adds a touch of realism to your motorcycle

Jon porkkaon Hot Racing Losi Promoto-MX 1/4 Aluminum "Titanium Look" RCT Pipe (Burnt Tip)

Bought from my lhs as my kid lost the stock end cap... put a PC sticker on this one and it looks awesome! If crashed lots with it on the bike and it's held up great! Literally no visible damage... my only complaint is dirt does easily get stuck in the end cap as the design easily packs with dirt from a crash

Great looks excellent function AFTER you relieve the opening for your silicone wiring. Its not a large enough opening and may damage to your wiring in time (IMO) The sharp edges where the wiring goes through are less than optimal for super soft silicone wiring...and yes, I am a design engineer...from the USA not China lol

Perfect fit and looks really nice. It takes a beating.

3 wheelies later after installing and it had bent and wrapped around the battery wires! I was lucky it didn't pinch the lipo wires, and it also took 20 minutes with the best name brand pliers to get it to pull apart enough! Unless you plan on using it as a shelf queen don't buy it!

What reviewers say

Reviewers agree the pipe looks good and fits well, and several report it holds up to crashes with little visible damage. Two reviewers note that dirt collects in the end cap after crashes. Opinions diverge on durability: one reviewer reports the pipe bent after a few wheelies and wrapped around the battery wires, while another found it withstood repeated impacts. A verified owner also says the wiring opening must be enlarged before use and that its sharp edges may damage soft silicone wire over time. Overall, feedback is mixed, based on four reviews.

  • + Looks good, including with stickers
  • + Fits well
  • + Holds up to crashes with little visible damage
  • − Dirt packs into the end cap
  • − Wiring opening is too small and has sharp edges
