Need a good side-exhaust header for Top/Novarossi .12
I bought a Duratrax Nissan GT-R as a roller a few weeks ago and then picked up an old, but new in box Top .12 (same as Novarossi CX12) for a good price. I was going to just use the Duratrax header, but the design is horrible. The inlet on the flange for the header is only about half the length of the port on the engine and there isn't enough material there to dremel it to widen the opening on the flange. Are there any manifolds/headers from HPI, Associated or one of the pipe companies that you would recommend? I'm going to use an Associated 7731 pipe for now since I had a nearly new one laying around.
Here is the car in question to show the shape of header needed:
IGT2- Dragon Racing short chassis, Leopard 4082, Hobbywing 150A
Redcat Rampage Chimera- CY 27cc, Baja wheels, upgraded transmission plate/bearings
Nitro Slash- Novarossi 2.5, Jato transmission, 17mm conversion
Duratrax Skyline- Nova Rossi .12 & Dynamite pipe
RC18R- Leopard motor, HW 18A ESC, Hitec servo
