RE: hpi mt2 tuned pipe
I have this pipe and do not like it very much.
1) Its a pain in the ass to install. I actually nipped away at the fuel tank support bracket to clear some room for the pressure tube
2) The pressure line comes off the bottom of the pipe. What a crappy placement.
3) It is not very durable. I think that my output tube began to bend 2 or 3 runs into it.
4) It's expensive
Just my experience.
