MTC exhaust questions
 

Hi all,

Been reading several threads but that's just raised more questions. Seriously considering purchasing and fitting the single can, basic stainless exhaust from MTC. First I'd like to understand:

1. How loud is the exhaust. I leave the house at 7am everyday so don't want to become unpopular with the neighbours.
Had a GPR bike on a 250 before which was verging on too loud.

2. Does the exhaust foul the OEM panniers?

3. Does it burn said panniers or top boxs which are fitted (mines is Givi)?

4. Any other mods I should look at doing at the same time?


Thanks for the help all.

Well you no doubt read a few of my posts ref the noise (too loud for me) and that the round one was way too close to the panniers. But someone popped up saying his fitted fine. I leave home at 5am so it was way too loud for me.

Hi redbikejohn.

Thank you, yes, your post about noise concerned me, but I gather the latest versions are quieter. Not sure if this is true or not though.

I missed your post about panniers, take it that was the OEM ones in both cases.

Thanks,

Yes it was oe panniers. You can sort of get it to fit as its possible to swivel the link pipe a bit but it was too close for comfort for me as the oe ones are plastic and only aluminum coated.
I was never that pleased with the way they sat in pictures but picked up one second hand for a good price to try. The gutted and drilled oe pipe is quite a bit louder than stock and this pipe was louder again by the same amount. Due to the angle of the frame and space I think its difficult to get one to fit as I'd like and still have enough internal space to dampen noise without affecting performance.

I have 2 Leo Vince end pipes on my XTX and they are NOT loud, just a bit more "full" sound which is great for safety in the city. Some extra noise is also generated on the intake side when you let the engine breath better (remove snorkel and so on).

Yea a friend bought one with Leo twin cans on and its wasn't much louder than my drilled oe. I was surprised it wasn't. Look nice but pricey.

Scorpion twin cans look and sound beautiful

...................so is there a single can that is q
not as loud as the mtc. I say this because I am seriously considering ditching the MTC. It is loud and when I originally got mine I was so concerned that I went back to the factory twice, the last time with the bike and rode it into the machine shop and gave her a damn good rev!. That woke them up.
It is still too loud despite different end pipes and the 'pepper pot. diffuser that they gave me stifles it too much.

So my question again is ther a quieter single can available?

SteveD

That's dissappointing, price was the biggest temptation but I don't want an excessively loud system.
Are the twin systems any better?

As with SteveD, any single exhausts available which aren't loud, too expensive and OEM panniers fit?

SteveD, you looking to sell yours? Right price and it might be worth a gamble with pepper pot baffle in.

Cheers all!

Yes. More volume of silencing material means a quieter exhaust. Also the greater cross-sectional area of the combined outlets means the pressure pulse is reduced (which is what causes the main difficulties in silencing a single).

Yes. Have a look at the various Exan single can systems. They start at very similar prices to the MTC for a round stainless version. Mine is pretty quiet with the baffle in, not far off baffled Leos or Akrapovic (which I had before) - a nice sound, but still polite.

Buy from Mad4Exhausts.com, not the UK importers, as they are considerable cheaper shipped from Italy to the UK privately.

Read this thread (if you haven't already?)

Hi,

I did read that post but got drawn into the tool tube you created. Think you should sell them on ebay, I'd snatch one up!

Thanks for the link, I dropped them a message for current prices. Exhaust does look nicer.

I was also admiring your high mudguard/low half mudguard. Def a mod for winter, running the high guard at the mo.

Please keep the informative posts coming!

Thanks,

speak to the guys at mtc and ask for the perforated disc which i have
tacked to the link pipe and i,am running the perforated baffle not the
baffle which is a tube with the end cut of.took it for it,s 2nd mot with
this setup and he said it was not to loud at all:041:

Hi Beany,

Not sure I follow, MTC supplied a mod to you which you fitted yourself?

How loud is the exhaust in your opinion? Exhausts can pass the MOT but still be unpopular in the residential areas!

Do you have any luggage fitted to your bike? Any issues with heat or clearances.

Thanks,
Penfold

hi penfold,i dont think the exhaust is to loud it was with just the baffle in but the extra baffle which i have tacked in the link pipe i think sounds good and not loud.i think it was 8 pound plus p&p.my panniers where the ortlieb soft luggage with the standard exhaust but now i have givi frame rails and alpos panniers.
hope this is a help to you.

cheers beany

Hi,

Thanks for that. Contacted MTC on eBay and then by phne to get no response in 2 workng days to a couple of questions. Little disappointed so took Pleiades (expensive!) advice and went for the nice looking, quieter Exan exhaust from mad4exhausts.com. The guys have been very responsive to all of my questions and despite being Italian are cheaper than UK stockists of the same products.

Looking forward to the new bit of kit now!

Cheers all,
Penfold

Keep us informed, very interested in this my self.

thanks

Hi,

Despite ordering it weeks ago, I'm still waiting for my new exhaust to arrive. Getting impatient now! Hopefully it'll arrive by Friday as it was dispatched yesterday. Once it's fitted I'll post an update on how it sounds and how the bike feels.

Ordered an Exan too
 

I just ordered an Exan oval carbon cap in Ti finish today. I may use soft panniers at some point in the future and therefore need to attach a heat shield to the end can. I figured oval was a more uniform shape than the X Black one they do and more likely to accept a strap on heat shield.

Before ordering I contacted Exan and they confirmed their pipes work fine with the OE hard panniers.

Hi,

I've posted an update in Pleiade's thread ( http://www.xt660.com/showthread.php?...d=1#post200734) about the Exan exhaust as it's not strictly on topic with the MTC exhaust thread here.

Get yourself either a bracket made up or a long M8 fastener, 100mm long is too long. 75mm is more than sufficient.

Did you go through mad4exhausts or the UK distributer? A bit slow, presumably waiting for bits to arrive from manufacturer as once dispatched it was here within 3 workings day (dispatched Tuesday, arrived today).

FYI - They never carry the posh ones (titanium, black stainless, X-Black) in stock for the Z (just the basic oval stainless), they are ordered in from Exan direct when you place your order, which is why it takes a while and once they have it, it ships quickly.

researching exhausts for my tenere I'm at the crossroads between

1) remove cat (cheapest, but irreversible)

2) exan (looks best, arguably)

3) mtc TWIN cans

I reckon all would make a good solid sound, but which option is less noisy? How is the mtc twin cans vs single can sound level?

The least noisy option will unquestionably be the de-cat stock silencer.

The Exan is the quietest of all the single can systems available for the Z (that I have heard/followed, and that's most of them).

The MTC twin can set up is a lot quieter than the single can system (which can be an aquired taste in terms of noise - some love it, others hate it).

Thanks for instant reply. How does the exan compare to the mtc twin?

About the same noise-wise I'd say. The MTC twin has a deeper tone though, if that's what floats your boat?

Deep sounds nice and the youtube video of the twins sounds great. Though perhaps I might change my mind after 30 mins on the highway...
If you say the decatted OE silencer is a lot less noisy, then that might be the safer solution.
