Soooo, I guess no one has ever done this?  Or have you?  Just looking for some guidance.

Had a listen to that.... Anyone know what it sounds like with only the down pipe alone, and no can at all? (for Americans i mean muffler, lol)

ChrisF..

LOL, i would have done the same, but cant cos myne hasnt run in over 10 years, and iv been trying to get the thing together for the last 6 months! But then i did decide to Drastically mod and chop myne, befor i even got it running as a standard bike, Doh! And i havent got a muffler at all, just the down pipe, if it sounded reasonable, i was just going to put a turn out on the end...??? What does it sound like with the Harley muffler?

Concur.

It's quiet, but lower pitched than the stock muffler.  It has a lot better low pitched resonance.  Kind of a nice thumpa thumpa thumpa sound.

And it's a good bit lighter in weight. At least 1/3 lighter, maybe half.

I had an extension pipe made for mine:

There is a chrome heat shield covering the Zinc pipe now.

I'm considering painting the zinc pipe with high heat black (or maybe orange) paint -the kind they paint manifolds with- and getting one of these over it:

Here is what I did...

Rather then removing the baffle all together, or putting a HD muffler on, I just drilled two holes through the baffle plate, 5/16" wide.  I didn't use the foot long bit as suggested before.

It sounds great and does not seem to have any performance changes!

I forget who's picture I was looking at, but someone has a blue header pipe on their Savage...well, actually quite a few people do.  So...

...if you ask about the effect of removing baffles, drilling baffles, or completely removing the muffler on a stock late model Savage, all you need to do is think "blue".  Bluing is not normal, especially when we are talking about a double walled exhaust header.  Bluing is the result of running the engine hotter by leaning the fuel mixture or lowering back pressure.  That is the effect, and if you don't want "blue", then you better think "jets" too.

There can also be more serious impact from completely removing the muffler than simple hearing loss (a condition that I truely have).  You also run the risk of burning the exhaust valves.

BTW - with the mention of Jon D's site.  Yes, he drilled out his exhaust, but now he has a SuperTrapp or Jardine installed.  So maybe there IS a better way after all....

Step one
Get running
Step two
Tune it, get it running Right.
Step three
Make mods.

If ya make mods before it's running Right ya can't know if it's needing jetted or what.
