I need to get a ex manifold for a .18 TM to fit a T-Maxx 4910. Do you know where I can get the O.S part number?

Here's the O.S. part you need, but it's been discontinued by O.S...

OSMG2618 72103610 EXH MNIFLD TMAX .18TM US$49.99

You will need to check the selling sites, swap-shops, and possibly auction sites to locate one. Neither we, nor O.S., have them any more.

I kind of figured that it would be dis-continued so I did a little inventing and have a different idea.I had an extra Traxxas manifold and the manifold that came with my 18 Tm, it fits a revo and not a T-Maxx so I cut both and used the end to the engine that came with my engine and the pipe from the T-maxx manifold. A little bit of fitting and a weld and presto it fits. Now my concern is, is the pipe it-self big enough for the 18TM. It was stock for the 2.5 and the 3.3. I don't want to do any-thing to mess up my O.S. I know you can't give me a definate on how well it will work, I am just looking for your opinion on the idea. I guess the question should be is if the pipe was O.K. size for the 2.5. and the 3.3. should it be all right for the 18?
