I've done some research on doing a baffle mod to the stock pipes of cycles in general, and came across two methods. One, drilling holes in the first wall. The second, using a hole saw to cut through all three walls and removing the baffles entirely. These sites claim no rejetting is necessary, but I'm skeptical. Any opinion or insight?

The bike is a '00 Honda Sabre 1100. I like my performance and don't want to sacrifice that for noise. I was leaning towards drilling a few holes in the baffles for a little more sound (not enough to warrant rock throwing) without needing to rejet.

If the exhausts have three baffle plates you can drill the back two without re jetting.

You should be skeptical.
If you reduce the exhaust back pressure by essentially bypassing the muffler, you will improve the air flow of the exhaust, generate a lot more noise, and yes, change the fuel-air requirements of the bike.
If you don't rejet, you will be running the bike too lean, and could burn an exhaust valve. That's a pretty expensive repair, in case you've never paid for one.
Plus, the improved horsepower from ruining your exhaust is minimal - 5% maybe. Not enough to notice, unless you are on the track, in which case there are many other mods you can do.
Bottom line, leave the loud pips to the dickless moron wannabes on the Harleys, and revel in the quiet power of your fine machine.
Think of it this way - some engineer went to a lot of effort to design your bike to be what it is. Why try to out-guess his calculations? If you are building a bike from scratch, sure, compensate for your poor design skills by making your bike a noisy POS annoyance to everyone around you. But if you have a good, modern, well-designed bike, why screw around with it?
Hope you choose wisely. Rocks to the head hurt.

If you have straight pipes you will need to rejet. I put straight pipes on my Harley. You could hear it for miles, however I started to lose my hearing. The noise would drive me nuts after 60 miles, even with a helmet on. Torque is decreased. I put baffles in and the driveability was much better. You do need some baffling for adequate back pressure/torque. Everyone will probably give you a different opinion. I put a S & S Super carb on and my mileage went fromm 44 mpg to 29 mpg. I did not see much of a performance gain, I'm sorry I put the S & S on.

I bet he doesn't throw rocks at the big trucks when they rattle his windows...
hehehe
Tell ya what
I heard you can take a 3 ft rod 1/2 to 3/4" round
sharpen 1 end and use a hammer to drive a bigger hole through the baffles
Have someone support the front and careful not to go too far in.
This will increase the sound and when you go to get it inspected they will see the baffles in place so it should still pass.

You didn't say what kind of bike.
Some bike mufflers will make a whistling sound if you modify the stock ones. Then you will end up buying replacement mufflers. Might as well look for a magazine that has done exhaust changes on your bike and see what gave the desired results.

Leave the damn thing alone. There is a fine line between sweet sounding exhaust and just plain noise. If you are looking for that deep throaty rumble that H-D's have forget it...it ain't happening with the Honda you got. Only bikes I've heard that come close to that sound are big bore Yammies. I've heard stock exhaust on Hondas like yours and it sounds pretty damn good as it is. All you will succeed in doing is pi**ing the neighbors off and looking like an a**hole in my honest opinion. And i don't care if you care about my opinion or not!

Well digbat did you ever hurd of back pressure???
Do you understand why the bike designed it with back pressure?
Well it seems to me that all you want is a loud bike and attract police to give you tickets for too loud pipes
Well go ahead and burn up your bike by removing the baffles.
More power to you, but I see that you just dont know what you are doing

David Dale and Tyrone Roberts posted the same question. You should see their answers side by side.
