New Termignoni pipes way TOO LOUD with bafflers removed

[rod796]

Hi all,

I installed my new slipon Termi pipes & high flow air filter a couple weeks back and they sound awesome; a deep loud thunderous roar!

Unfortunately though, I have decided that they are just way TOO LOUD for me, my neighbourhood, random car alarms, little old ladies and baby kittems.  In fact, they are much louder than my old 620's CF Termi pipes, I don't know if it's due to the slightly bigger engine or the fact that they're full metal vs carbon fibre pipes.

A bit of recon around the forums and I have found other people who have the same concern as me, example below-
http://www.ducati.ms/forums/77-sport-classic/41125-termignoni-baffle-mod-2-2-slip-ons.html

So for now, I have put my baffler's back in and the sound is like the stock pipes

I am planning to do this mod as suggested by LeeC from Ducati.MS to get 70% sound.

My questions are-
1. Does anyone else actually run with bafflers in on custom pipes?
2. Has anyone done similar mod to bafflers?
3. Will I need to get engine re-tuned after this type of mod?

Betty has baffles in for that same reason and his sound like tweettie birds, just the way he likes it.

Rod before you attack the baffle with an angle grinder , buy a quality steel drill bit and whack in some more holes.
Just keep adding holes until you get the degree of LOUD you want .
If you cut the baffle's off straight away you cant go back ! and it may be too loud again.
My two cents worth.

thanks for the advice, I will give that a go first

Rod, I can't see your piccies from where I am so just comments for now.

The only time my pipes have not had baffles was in the workshop when the exhausts were installed. I heard the bike without the baffles but I was still wiping the blood away from my ear lobes* when the baffles went in ... and I like the sound of my tweety-bird baffles (but I'm weird) ... and they have been in ever since. But I don't know how my baffles compare to others.

So yes, there are people with baffles and I can understand the 'too loud' call ... like a certain yellow 620 which can cause heart arrhythmia if you are in the blast zone or early onset DVT if your calves are positioned wrongly when sitting on the bike.

With regard to the tune I think that the simple answer would be ... it wouldn't hurt. But in my opinion (and I have no knowledge to back this up) I can't imagine it would make a significant difference whether the baffles are in, out or modified.

* This is an exaggeration ... I remember thinking 'faaark that's loud' ... but the guys in the shop stood back and said 'hmm, it's not as loud as I thought it would be'.

From my  research, before I cut my baffles on the stock pipes, there is no need for a retune unless you go the open airbox route. (which you've gotta do if you want to make it sound like a real Duc)

Hey Jukie!! I think Betty is taking the Piss!!?? 

[Jukie]

Thread jack, yes Dragon, Betty always take the piss out of me

I'd certainly agree with Dez on the mod. Do some drill work first to find a desired result and see how you go.
The loud effect might also have something to do with the fact that the pipes are closer to your ears, shorter than the previous Termi's of the 620 and look like they have a bigger bore.
These factors might be contributing to the "loud" effect and yes it could have something to do with the engine.
I know when my old pipes went on Nick's bike they did sound different than on the 620.

Though riding behind them I still hear them over the top of my bike! They are LOUD too!

+2 on the drilling.

Subtle but truthful is the way I would have described it

Now that I can see the piccies ... the length of the modified baffle seems closer to mine than the unmodified. Can't really comment on the design though or know for sure (I'm old and its been a long time). My baffles have been in so long I don't think I could get them out even if I wanted to.

But I wouldn't say my pipes are exactly quiet either ... so the drilling option may be your preferred starting point.

I have also heard (or read) quite often that the standard pipes on the 'new-gen' monsters don't sound too bad / are not so quiet ... so your starting point may have already been a bit different.

Can you get baffles as a separate item? Modifying your only baffles might get tricky if you ever need your bike to sound like it does from standard (RWC, dept transport, fun police etc) and keep the termis on the bike.

Personally, I'd try cutting just the blocked end off and keeping the long length of tubing and going from there.
 
I agree you can tune your sound easier drilling holes but I find it is harder to weld up a lot of holes rather than weld a bit of tube back on. Just a thought.

PS. 1 vote for no baffles, not my bike I know but just my 2 cents.......

My 2010 M1100 with Termi's slips (no pipe kit) with baffles is waayyy loud, comparable to my bro's Gixer1000 with shorty Jardine racing pipes. My wife says she can hear me about a 1KM away and knows when to put the kettle on  

I like a loud bike and and my house vibrates when the bike warms up in the remote garage and so haven't even considered taking out the baffles as a result. I don't quite understand how peeps can compare the Termi's + baffles to the stock cans which were very mild IMHO.

I have a decibel meter on my iPhone, its not accurate but can be used for comparison. Over this weekend I'll try and measure the reading with and without baffles to gauge the percent increase and post results.

You need to lose those chicken stripes to mate

I like the sound my stock exhaust makes.  

Just sayin'

I'd modify or replace the cans to reduce weight or otherwise improve performance, but wouldn't want it any louder.

Have always loved my DP (Remus, not Termi) carbon cans.  They were part of the reason that I bought the bike but I do pity the neighbours when I depart for work at 5.45am.
