pipe
 

recommended topend pipe for IDM Picco P9 Evo3 .21?
not worried about fuel economy,noise or efra ratings (for 1/8 pancar project).
thankyou;)

Go with the pipe that is made for it, PICCO 2033 pipe set.
other option is a Novarossi 2052 with a short conical manifold.

those are flat out topend mufflers?

Well, if you don't care about rules try a good old Nova (or RB, Top, Rex, JP, etc) 9886. It was pretty much the HP king for all motors before regulations killed it.

thanks for the help!
ok i have a ofna 086 and a sirio 2013,which would be better for my use?
sorry for all the ??

I don't know how they will work with the Picco motor but the 2013 is a beast on most motors. The 086 might be even better being a 2 chamber pipe. The Picco pipe Sam suggested should also give great power.

I just read this post. You can use the IDM 2033 pipeset and also the 2013 as stated they both run good. The 2052 will give you a bit more top with a loss of bottom end. So stay with those 2 and you should be fine.
