There are some pictures on page 8 of this topic that shows the fit of a TT 120RP in my Excelleron. I'm using the 1.75" TT header and pipe.

Does anybody have an idea how much rise the header would need if using a TT120 RE and going with the same pipe tunnel that Aerobob is using? I think the standard MACS header is a 1.75" rise, with a 2.25" also available. I'm thinking of using a Weston Mini Pipe as they're fairly quiet according to Volfy in Glow Engines, not particularly expensive, and alot shorter than a full blown pipe. Not to mention that Weston now has a USA distributor and I'd like to see them get off to a good start, Weston has some cool products.
