From AI:
Here are more details about this specific item and its background in the nitro RC hobby:
Brand & Function: CVEC Incorporated was well-known in the nitro RC community for making specialized, high-performance exhaust systems—most notably their variable-volume or multi-chamber tuned pipes and custom manifolds.
Component Kit: The TM03 package contains the exhaust header/manifold hardware designed to fit small-block nitro engines on the Traxxas T-Maxx chassis.
What is Included: Based on the visible contents in the sealed bag, the kit includes:
The metal exhaust manifold/header pipe.
Gaskets and mounting hardware (such as screws and a flange).
A tube of high-temperature sealant (Permatex gasket maker) to ensure an airtight seal at the engine block.
Clamps or zip ties and installation instructions.
Collector Value: CVEC parts are vintage/discontinued aftermarket upgrades. For hobbyists restoring or maintaining older classic nitro trucks like the original Traxxas T-Maxx, unopened vintage option parts like this are a rare find.
