How do they go compared with the 2072 for fuel economy.?
The Werks pipe also sounds good, might be worth trying after trying the GO pipe.
We haven't really had a chance to compare economy on the two GO pipes yet.
Race season starts this coming weekend, so will have a better idea then.
Most people that have the new motor are just running the new pipe as a matter of course.
The 2072 was never a super economical pipe, and just going on the performance we have seen so far with the new 2103 pipe, I would say it would have the edge over the 2072 in the economy stakes.
If you get a chance to run the Werks EFRA 2058 give it a whirl. This pipe is very popular everywhere with club racers and pro's alike.
We have guys here running them on the Werks motors, plus RB, Nova etc and loving the power and economy this pipe produces.
It's basically an on-road chamber with a long off-road header, so best of both worlds. Great buggy pipe on most motors I would think.
We run the 2058 on the B5 Werks motors in truggy too, as the more torque designed 2013 pipe is not legal here (under the IFMAR rules we run).
The 2058 has a slightly smoother bottom end, but still enough stump pulling power for any corner or jump, and compared to the 2013 it gives approx 45 sec more run time per tank.
