So, 2072 in truggy and 2103 in buggy would perhaps be a good guideline.
The Werks 2058 is also a brilliant pipe. We have run this on a couple of GO motors including the .25 6 Port, and it's a sweet match up. Slightly smoother (but still very strong) bottom end, with enhanced mid range power and definitely more top end. Improved economy on the .25 as well. More expensive than the GO pipes, but very nice.
Thanks Grizz, sounds like the GO 2103 might be the pipe I'm after, my engine is made to have a lot of power right through the rev range & a very strong bottom end so a pipe with more mid to top & similar or slightly less bottom end would make it just right. 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.
