Model Forum / Radio Controlled / Land Models / February 2007Custom Exhaust Help
I have a Hyper 7 buggy that I am mounting an engine in that is made to fit a Traxas vehicle (It's a TM323 with a TMaxx Mount). After making my own engine mounting plate, the only thing left is the exhaust. Since the motor is much shorter than a regular big-block, the exhaust port on the engine ends up about an inch forward of where it would be with a standard big-block. This makes the pipe end up way to where it actualy hits the front tire. Anyways, does anyone have any experience of guidence on making a custom header? What would work great is if I could substitute a couple inches of flexible hose for a header, but don't know what materials would be suitable. Any help will be appreciated.

Thanks How about using a Revo header and pipe? Run it perpendicular to and behind the motor. Sounds like you should have enough space to do that!

You could also go with a short pipe..I would suggest a CVEC for Traxxas. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBYG2&P=7 Probably can find one on ebay,just be sure it's the short version.. > >>I have a Hyper 7 buggy that I am mounting an engine in that is made to > >> fit a Traxas vehicle (It's a TM323 with a TMaxx Mount).

You bring up a good point............GTD, were you trying to use the big-block pipe with the Traxxas header and TM323 mill?

One thing I may try is the origonal pipe off my kid's revo with a buggy header. >>> Can you hack off an inch of the header? >>> You could also go with a short pipe..I would suggest a CVEC for Traxxas.

You're going to have to use a smallblock header and pipe on that TM323 as it will be bog city with a big-block header and pipe. The buggy header probably won't work on the TM323 anyways as it will be much larger than the exhaust port on the motor. The CVEC's as M78 suggested are short lil' boogers and given that they are adjustable, would probably work with a smallblock motor and the stock Traxxas header.

I re-attached it at a different angle with a rubber header-to-pipe coupler. HOPEFULLY, , It won't melt, since it's going to be only about an inch away from the engine. This way, the TMaxx pipe can be fit in there. . I'm waiting on a clutchbell, some bearings, and the weather to warm up a little to ge thisthing finished and the motor broke in. > I think I have a plan, but there's a chance of it failing: I cut the > TMaxx header that came with the mill right in the middle of the 180 [quoted text clipped - 4 lines] > I'm waiting on a clutchbell, some bearings, and the weather to warm up > a little to ge thisthing finished and the motor broke in. Rubber (?) or the standard silicone coupler? The former will melt, the latter will be fine.
