Re: Exhaust restriction
Jumping in a little late, and I am on my phone at work.
The *normal* end of that stock ezgo muffler has no crimp in it at all. It is about 3/4 " round opening. If it was me I would open it, it won't be that much louder. As far as air flow and hp, if you open up one of these robins and say put a header on, the intake side (stock) is so restrictive (airbox and such) not sure you will get the results youwant by just modifying the exhaust.. In other words, if you're gonna open up one end, better plan on larger jet for the carb, that CPP has, and cold air intake ( the stainless or billet version) withK & N filter. I put a home made connector and a Kand N filter on and dumped the Airbox, but it made starting it a whole relearn adventure.. |

I better pick up a couple new hack saw blades. I'm guessing you'll want good blades when working under tight conditions. |

Re: Exhaust restriction
I GOT A GREAT DEAL ON THE HEADER/MUFFLER. SO NATURALLY I PUT IT ON. I HAVE NOT CHANGED THE JET IN THE CARB OR INTAKE YET. BUT, IT IS TAKING OFF HARDER THAN BEFORE. IM ALSO GOING TO MODIFY THE STOCK AND COMPARE THE TWO. IVE HEARD EVERYONES OPINION, AND DID NOT REALLY FEEL THAT ANY ONE GAVE ANY REAL PROS OR CONS.
OH, THE HEADER/MUFFLER MAKES MY CART SOUND KINDA LIKE A VW BUG |

that.. BUT, I could tell it wanted to breath a little more (as in a header) but I never did that..as I had my long term eye set on the twin. |

If you take a nice 10" flat blade Craftsman screwdriver..or Blue Point Snap On if you are so blessed, and stick it in that slot, and wiggle it a bit, and then push it in about and inch and give it the old back and forth, in and out, round and round..you will have a stock opening in about 15 seconds. Save the knuckle for another day..you'll need it. |
