For those who want a side mounted Pipe, and still have a small block, here is the solution:
First buy the O.S. .21 RG header.
http://www2.towerhobbies.com/cgi-bin...?&I=LXNW29&P=7 Then buy pipe of choice if you don't already have one. Screw the O.S. header on. It should fit. Next put the pipe on, and secure it with the manifold coupling. Done. Find some way to secure the end of the pipe to the chassis, and you are done. It will fit if you are using a pull start, and any 1/8 buggy screw on manifold should work with a pipe if you are using a bump box, and sealed back. Note, this is for TRX 2.5 and 3.3 owners only. For BB's, a normal 1/8 buggy pipe and header will work fine, and should make it easier on you.
So go buy a BB!!
