Hmmm...the 2.5 upgrade kit? If you mean the one for dropping a TRX 2.5 in place of the TRX Pro .15, then this is what you want. CLICK HERE If you are looking for all items necessary to convert a stock "old school" T-Maxx to a full up 2.5 T-Maxx, that list is longer.
As for the 2.5 Head fitting a Pro .15, that question might be better answered by TRAXXAS. I am certain the bolt pattern is similar, but could not in good faith tell you for certain.
Alright thanks. I have the Tuned Pipe that Traxxas put out for the Maxx too, is it possible to continue using this one instead of using the other pipe that fits the 2.5 like it should? I think the pipes on the 2.5's are UGLY.
Yes, but while ugly that pipe is made for that engine. This means that it is optimized for the 2.5. You might find that, in this case, function over form is a good thing. Besides, you can hide it under a nice body.
I have the Traxxas Tuned Pipe originally made for the .15 but I read that it will work on the 2.5 too. So I think I sm gonna keep that or get a Dynamite Blue Pipe with Full Header. We'll see.
About the Tuned Pipe, where can I get a full header or two piece header for the T-Maxx 2.5.
