Baffle Removal
05/27/04 at 13:56:38
 
I have a 1997 Savage, and I want it to be louder.  I was wondering if I can remove the baffle with out working about the back pressure.

Can I drill out the rivits holding the baffle in place?  Do I have to adjust the carb or anything after doing that?

Check out this site: http://www.jonline.org/savage/Tips___How-to_s/tips___how-to_s.html

He's done quite a bit mufflerwise and covers drilling stock mufflers.

Yes I do.  When I put on the Harley muffler on mine, do you think for minute that I didn't start it up to see what it sounded like "raw"?

  • 1. It's loud.

  • 2. It's loud.

  • 3. Higher pitched, more of a "brappp, brappp, brappp," sound, but louder.

  • 4. It's loud.

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?

I have a harley muffler and it sounds great. I think it's pretty loud. I was told if i want to make it louder use a heat gun too hollow out the baffle.
I get alot of comments on how good it sounds.

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!

  • Funny, after riding around on it for a month it no longer seems to be very loud.  I wonder if I went deaf?  ???

    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....

    Well I am 20 years late. I was 4 at the time of this post, but I recently de-baffled mine with a circular saw drill bit. I forgot the size, I think it was about 1.75 to 2 inches. Worked perfectly. I honestly like the sound, but it does need to be rejetted. Backfires bad running super lean. It doesn't help that I am at sea level down here in Mobile. Once I rejet the bike, I may upload a video and post it.

    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.

    I've never done an exhaust after tuning a vehicle. I've always tuned after the fact. The bike was going to need a rejet anyway given how lean they come from factory. I got a stage 1 kit from sixsigma. Currently restoring a boat so unfortunately the Suzuki is a secondary affair.
