drilling muffler

Post by gobucks »

i read on another site that you can drill four holes in the flat back part of the muffler that are less than a 1/4 inch in diameter and it helps a lot with acceleration and top speed, would this be good for a honda elite ( it was recommended for a yamaha)

I would not do it. Reason being the engine is a 2 stroke and it needs back pressure to run smooth and create power. On another note, I would imagine it would be really loud.

Theres been alot of people over the years that have tried all sorts of things to create more power. Most people that know anything about drilling the stock pipe suggest drilling 2 baffles out of it by drilling them through the exhaust pipes outlet.

* info, you want to put a drill in the exhaust tip and take out 2 restrictions. Only on a spree or elite, never do this to a aero muffler.
I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.

Kenny, why not the aero muffler? Just curious because I looked in the end of my aero muffler and it did look different than the elite muffler. Different design?

The last time I told osmebody to drill a aero muffler the bike wouldnt run right afterwords, IIRC he ended up cutting it open and having the holes welded in.
