Recommended Pipes & Mufflers for OPS .67

[Jim Walters]

I have ops motors for my scale and was wondering since I know that many used to or still do run them, what the best pipe and or muffler combination that you used? Also the length that you used.

Thanks in advance

Always had good luck with MACS 11CC pipe

Comes in both Nitro (unmuffled) and a muffled version.

Just don't get the "super quiet pipe" too many baffles, and creates too much back pressure, and heat

Aeromarine would probably be your best bet to get one, or direct from MACS Exhaust.

Good luck
