I am surprised to find this out but not really.
I have an SBP Expansion chamber setup.
I took the muffler off the end to clean it.
The fiberglass packing was soaked with oil.
So i took it out and put it all back together.
Things were ok and it ran good.
Somehow after a coupla days the pipe that threads into the end of the expansion chamber broke off.
I got the threads out and attached a pipe fitting to it so i could screw a regular lawn mower muffler to it.
It is running like ****.
It used to rev to no end now it feels like i got the stock pipe back on.
So what is making the big difference here.
Is it the length of the pipe "stinger" that matters??
Apparently the exhaust is tunable from the muffler end.
I just want to get this thing running like it was.
Anyone have any experience with this????
