Port size

[RcJunkie13]

Is this ok? Port is smaller

 

[Rep732]

It will do but its not ideal. Cheap pipe? Looks to be

 

[RcJunkie13]

Yeah, cheap pipe, but it’s no biggie right. Will it have a significant performance impact?

Paging @Seandonato73 .. im no expert in 2 strokes. BUT I can say a smaller port where the exhaust starts it journey is probably not going to get as much of the exhaust gases out as it should and its not optimizing the full potential of a "tuned" pipe and also using the most out the exhaust stroke. from what I've been told a long time ago an exhaust is as big as the smallest diameter . also this pipe will most likely give you something over a stock can and depending how large the flange is with how close the welds are to the inside of the pipe you can probably port it with a Dremel with a standard gasket as a template to see how much to remove.

VS a can YES any day , looks like that pipe was for a smaller motor

 

[RcJunkie13]

Made to fit a 36cc, I have one and it is the same port size of a g320, idk why it’s so small, but yeah it’s gonna be good over the can.

 

[Seandonato73]

That's gonna hurt you more then anything. Return that pos and get something else

 

[RcJunkie13]

Dad took it to work and its getting ported to a regular gasket.

Round hole square peg anything is better than nothing ?

 

[Rep732]

Better than it was

 

[buzzkill]

YA WAYYYY better calc the round vs square for max cap.
