you will need a header also, anything is better than the stock 'can' type muffler HPI puts on.

Depends on what you want really but its fairly simple.

If you want a good top end pipe like for long back straights etc then you want a long, thin shaped pipe. Something like a MIP set up correctly will sing on the top end.

For good low end, something like the Paris Turbo ring would be a great pipe.

For all around my choice is always a RB X12 pipe or any of the Nova rossi type pipes.

Keep in mind if you dont set the pipe up correctly off the header it wont do anything for ya.
It needs to be positioned correctly off the header (distance)
You will just have to experiment as there is no real specs because each motor and pipe combination is different.
If you know someone that has used a particluar combo that might be a good try.

MT-12 and RB X-12 is awesome, use the RB header and space the pipe about a 1/4" off from the header.
This is just an example but one that works...not cheap though

Good luck
