New Termignoni pipes way TOO LOUD with bafflers removed

[rod796]

With a break in the wet weather on the weekend, I finally got around to doing the chop-chop on my bafflers and here are the piccies of my handywork.

In summary, and in my opinion it was only a slight increase in overall sound, less tinny and slightly bass'ier at rev's.

Next I think I might try a couple holes in the surrounding ring as per initial diagrams.

I cut at the 7.5 cm mark with a pipe cutter which I figured would be close enought to the 3" mark.








Before anyone comments, I know the nut is not alligned in the picture!

Having had a look at your pictures pre and post surgery, I'm still perplexed (dare I say baffled  ) about why my Termi inserts did not come with the perforated ends that you have. Mine, as stock, look identical to yours after you cut them.

I can only imagine that later termi kits come with the baffles like yours/mine as standard. Has anyone else who has recently bought the Termi kit for an 1100 able to verify if your baffles are like mine (see way below) or closed like rod796's pre-cutting?

I have an 1100 evo and the Termis were installed 2 month ago. Mine also do not have the perforated section, and in appearance are similar to the post cut pictures (as posted by rod796).

I prefer my inserts out but I put them in for a ride through the RNP yesterday. The reason is that without inserts the engine is running lean with lots of back fire and popping when decelerating. By putting the inserts in it seemed to alleviate the lean condition.

This is a PIA as I got the termi system that includes the ECU but will still end up with having to look at after market options to get added performance and that unbaffled sound.

Ah ha! That explains it, Termi saw the light and saved some after-market butchery

I assume the 'running lean' you mention is the popping in the exhaust that you can now hear but the stocks probably deadened (plus the lower back pressure making it more frequent). It's something I've had on all my bikes I've ridden with sports exhausts to varying degrees, although the Gixer1k with the Jardine GP-1's was kind of ridiculous. I regard it as a part of the whole light-weight, less noise-deadening effects of the Termi's.

I kinda like it anyway but then I'm a menace to society , but to each his/her own

I must admit I also enjoy the hoon perspective attached to loud unrestricted pipes . Now that I  tried the  bafflers  I think i will keep them out.

This is what the baffles look like from my Termi's (and the Tremi's without them in).

Dunno how the pipes sound with the baffles in though??? They sound too good as they are and my neighbours are used to the noise.

Also let's my wife know when to open the garage door and put the kettle on.

That explains your name then, eh Rowdy

AAh!! A variation on the "Automatic Garage Opener" Theme?? 

[Rowdy]

Yeah, works well.

BTW I've ordered the carbon/titanium Akrapovic muffler from their evolution exhaust system  to replace the twin Termi's. It is not the slip-on, but the muffler only from their S4RS full system. I couldn't get a full system that I liked so I am making it from bits and pieces.

Once I get the new muffler, bracket, a custom two-into-one joining piece and all the other bits I'll be selling the twin Termi's (will post advert in proper place then). Expected early next year.
Sorry for the thread jack.

Great looking Termis . How close is the lower pipe to the rear tire?, maybe the camera creating an optical illusion but they appear to be close.

About ten millimeters.

FWIW, I finally found the perfect loudness and tone for my Leo Vince system by cutting the tube completely off the DB killer then installing it between the muffler and midpipe.
Loud, but not too loud, with lots of bass.  If you stand next to the end of the muffler you can feel the concussion (like being close to a sub-woofer).
Me likey! 

[Rowdy]

That sounds pretty neat.
Have you got any pics?

There seems to be a fine balance between adding restrictions in the exhaust system to decrease the sound level and freeing up the system with cat-eliminators etc to get more power, better fuel economy (more noise) etc. I know we don't ALL want to ride open exhaust noise machines, but a well tuned bike with the correct size full system and appropriate mufflers doesn't have to blow everybodies ear drums out.

I agree. I put a Marving header (eliminated the cat) on my S2r1000 and it made a tremendous difference in tone and loudness. My bike had the Leo Vince on it when I bought it but, I'd bet I would have been real happy with the sound of just the Marving and the stock mufflers.

I think I read it here but a guy just replaced the mufflers and link pipes off his udder with a couple of slash cut stainless tubes about six-eight inches long and ran it like that without any problems and with a cool note.

Just have to make sure the tips are lower than the front cylinder head so it doesn't fill the motor with rain.

I'm sure the Leo Vince slip-ons look pretty sweet though.
