This is a great truggy pipe! I am using it with the protek 85mm header on an AD2. Has nice bottom end when you need it and the power delivery is much smoother than the 2100. I would recommend this pipe for buggies as well paired with a 75mm header. Has plenty of top end to get the job done.

Seriously $150 for only a thin pipe and plus no header? I don't mind spending money on R/C items but that is just dumb. There are way better pipes out there for the same performance and a lot less money!

What reviewers say

Reviewers generally rate this one-piece tuned pipe highly. Two verified owners describe smooth, responsive power with good bottom and top end, one using it on a truggy with a 85mm header and suggesting a 75mm header for buggies. Another praises its quality and responsiveness with an OS engine. One unverified reviewer rates it 3/5, objecting to the price for a thin pipe sold without a header and arguing that comparable alternatives cost less. Price and the lack of a header are the main points of disagreement. Review count is small.

  • + Smooth power delivery
  • + Good bottom and top end
  • + Responsive with OS engines
  • + Quality build
  • − High price for a thin pipe
  • − Header not included
