The glass fiber is never crossed by the exhaust gas, never ! It's not a filter. The glass fiber with holes is just a sound wave absorber. Not an exhaust gas filter ! So if you not remove the little cap at the end of the baffles, don't wrap with glass fiber.
I just bought some of those baffles on Amazon for like 10 bucks each. I took the plug at the end out of mine. That seemed too restrictive in combination with the fiberglass wrap. I haven't put a ton of miles on them but my 1975 Honda CB750 is quieter and has less popping on decel. Sounds better than the open non-baffled mufflers, and the RMP's seem to drop quicker when I let off the throttle. It would hang up just a little with the old open pipes, no matter how I tuned it.
I think if you remove that little cap you placed on the front of the baffle, you should get back a bit more lower tone, it will work like a gun silencer but will let the gasses and carbon out rather than choke up the glass fibre and make the engine run crapper and crapper. Just a thought. Right now it sounds and looks very nice. I think your vids are cool and helpful so please don't hate me for saying. I just purchased a 1 1/4" bit of ally bar to block the balance pipe on my TR7RV 750 78 hoping it will do the same for me as it did for your Bonneville. I too have a second bike which is a Yamaha XT600 1987, I have renewed almost everything on it but made it unique. It is a mice big thumper.
Do you have to make any kind of adjustments when doing this? I bought an aftermarket pipe but it turns out to be a straight through. It's so unbelievable loud I just felt like a fool riding it, not least for my own hearing let alone my neighborhood. I was hoping I could install a baffle to bring the noise down to make it more tolerable, I wanted slightly louder not atomic bomb.
Hi Knight I never made any changes to the carbs if that's what you mean, just try the baffles without the cladding as they make it a little more bearable
@@OldBiker Yeah to the fueling or anything is what I meant. I am hoping to put a baffle into this straight pipe to quieten it down. It doesn't have a hole for screwing a baffle in in but hoping I could make one.
Hope you don’t mind me saying but I put a set of baffles in my XS650 exhausts like those without any wadding! Sounded great but strangled the bike, I could barely do 70 and on hills could just about do 60. Take if for a ride 👌 mine are different exhausts as I took off the same ones your using as they were too loud. Hope your lucky 👍
Hi Tony, nah dont mind at all, I think I will change them out as a mate of mine has got a set of Dunstall silencers he said I could have, he just purchased them for his Triumph but didnt like the look, I'll see what the bike sounds like with what I have now and check the plus and see if they made any difference while its nice and sunny where I am and then go visit him for the pipes
@@OldBiker I found those tulips quite loud and even sound louder than the straight through ones on mine now (I took the baffles out in the end as it was so bad)
@@OldBiker please excuse the intrusion of your messaging, but I have to totally agree with you on the great sound of the Peashooters. I have a 78 750 Tiger (Bonneville single carb) which I wanted to install the T120R 650 Burgess pipes on as they sound just awesome, I had a 1962 T120R. Peashooters in my opinion sound the same but slightly louder, and do look great.
Can’t see that working, you are forcing the exhaust through the glass like a filter, not only will it choke the heck out of it but it will thrash the glass in no time
@@OldBikerhere's an old trick from a young biker raised by old bikers lol, use a pipe crimper + a screwdriver shaft to dent grooves into the original baffles, stuff the grooves with strips of packing. This sounds nuts but it works really well

Not surprised you're chuffed, looks and sounds spot on
Nice bike!! Great info on the baffles!

Im thinking of doing exactly this, did you encounter any problems after installing?

Changed em over to Peashooters, nicee sound and looks now!

You’ve done a great job and it sounds great too
Check out the new peashooters Glenn, much better sounding!
Woop woo

The originals would probably be better if you wrapped them.
If Ii wrapped the originals I wouldn't be able to get them back in
