What turned pipe to run with a Novarossi VIR-TUS Tuned 9-Port .21 XLong Stroke ?

Never owned this engine personally but friend of mine was running his with the 2015 and the 2122 pipe with good results. Seems like you can't really go wrong with the 2015 pipe seeing as its the most popular choice for many people. I believe the 2122 pipe is very similar to the 2015 too.

Thanks Glutton

Thanks Fan for the link good info.

51010 pipe (2015) with the 41015 header

Thanks for the info on the 41015.

It is also wise to try the 41016 header as well. it does give more bottom power w/o much loss on top rpm. Depending the track it could be the better choice.

Nice thanks Roelof, its always good to have some bottom end power and without to much loss on the top end that sounds like a win win.
