Stock Exhaust Pipe Modification by
Stanton High
The
stock Honda exhaust pipe is an extremely good pipe,
its been proven on a dyno that the stock pipe makes
the most power for the stock motor. Here is a couple
things I've done to maximize the output without spending
much money.
All you will need is a long metal punch (1) a hammer
(2) a 8mm wrench (3) 3 small washers (4) and I recommend
a flashlight to see inside to make sure you don’t
break anything you don’t want to. |

There's
a baffle and a spark arrester on the end cap. Lots of
people remove the end cap and spark arrestor completely
and think it has more power, but it doesn't. Removing
the end cap takes away the exhaust back pressure needed
to make torque. I also think it makes the engine sound
horrible. The mods we're doing will make it sound a lot
bigger. It will definitely be louder. If you have
any complaints with the unmodified pipe DO
NOT DO THESE MODS! The removal of the baffle
is permanent, so be sure. |
The baffle can be hammered on with a punch and it
will break down pretty easily. Be careful to only
knock it down in the center, if you miss you could
poke a hole in the can by accident.

I've
heard of cutting off the spark arrester screen, I don’t
think its worth the cost of a ticket. Find three thick
washers and put them between the cap and can “Supertrapp”
style. |

Remove
the white seal and throw it away.

I always recommend tuning your carb after putting on an air
filter or exhaust, you wont be able to take full advantage
without it.
Next = Carb Tuning!

a bad accident and half his body was burned. "It was
hell," Stanton recalls. But after four months and 13
surgeries later he got back on the xr50 and is now riding
harder than ever. These days Stanton rides as much as he can
