I am impressed by the quality of the pipe ... low price

So, it's not a pretty pipe. And at first look, I thought it was a replacement pipe for the RTR... it isn't. I bought this pipe on advice from a friend who said my run-times would improve. He was right! I got two extra minutes out of my Go-Tech 7-port in my 8ight *truggy(!)*. There was no loss in power, either. 5 stars.

GOT this tuned pipe for my novarossi toro nero .21 T and what a sweet sound it makes i can hear it ova all the other engines at the track not that its loud tho just a nice sound in the truggy races and the power coming from this pipe is just great heaps of power from low down to top end

Got this pipe to replace a GRP 3009 pipe on my Clockworks modified Ninja MR21 B01. No loss of bottom end and a simply put ballistic top-end. This simply suits the engine much better. It had no ill effects on runtime. they are still around 9-10 minutes in my 8-T 2.0.

GIves xlnt runtime and very smooth, at the expense of bottom end and punch. If your engine has more than enough power for your track and you can give up a bit of it ,this pipe will give you a real controlable feel and xlnt runtime almost 1 minute from jp pipes.

I love this pipe! On my EB Mods Vspec it made it very smooth and I was able to get 10+ minutes on a tank in my buggy. I'm running it on a Dynamite .21 right now, I think that motor doesn't have enough bottem end to use this pipe though. I think an 053 will work better for that engine.
