Okay so as i have stated in another thread i have ordered received and fotted the exhaust today and its a bit of a beast!!! Well made for a cheap exhaust. Welds look good and the stainless looks okay but im not metal eggspert.

So fitting is a tad fiddly but a 5 out of 10 for difficulty. The biggest issue was keeping the exhaust gaskets in place whilst u feed the header pipes in. 1 was loose the other was fine.

Its pritty loud i must say (awesome) and sounds very gruff and angry will lots of barble on off throttle.

Will ride with it on tommorow and see how it goes. My biggest concern was i did not have a small torque wrench for 16ft pounds so have roughly guessed it (so scared of cracking the head.... when i removed them 2 were very loose and the other 2 a fair bit tighter.

All in all money very very very well spent

Okay so after 2 days riding i flipping love it but i am concerned its toooooooo loud....i dunno. Also i get a fair bit of popping when decelerating and gear changing (unburnt gasses im surmizing)

Does this need addressing or is it okay to leave like this? I just dont want to damage the engine

Hi. How you getting on with the tec exhaust? Had it a while now. Are you finding it too loud still?

I only just saw this thread and wanted to share this as I feel it is important people know; (from my good few hours of research on both the MT07 and XSR700) ideally you should really look at getting the bike remapped (ecu flashed) for the aftermarket exhaust; as any straight through aftermarket exhaust (other than the official akra (with cat))will damage the bike over time without correct fueling. People seem to overlook this a lot but it is very important for these bikes as they run so lean and hot.

It should also be noted that people will say "the stock oxygen sensor will allow the bike to adjust itself", this is not entirely true, the sensor can only make very minor touch-ups, it can not adjust for such a drastic change such as straight through exhaust or high flow air filter.

I put a Yoshi R77 on my bike for a few days and the lean condition was incredible. I have since taken if off until I can find time to send the ECU away for a touch up. only thing is doing this will stupidly void the bikes warranty (according to my dealer). But then again, so will doing anything to your bike other than looking at it (according to my dealer), so check for yourself before you do anything

I don't mean to be a partypooper but I care for the health of other peoples joy-machines! Cheers and happy riding.

In the UK for sure if there was internal engine damage, eg a burnt out valve, then an aftermarket exhaust / flashed ECU would probably mean that you wouldn't get a warranty repair. If the problem was paint peeling around the headstock, then the aftermarket exhaust / ECU wouldn't be a factor.

Confirmed by my Yamaha dealer here (EU: Cyprus), but fitting an after-market exhaust will only affect warranty if it is determined that the exhaust was directly repsonsible for any issues that may occur. Any dealer saying otherwise is lying or has a poor understanding of EU laws in this area.
Serious, irreversible problems are not very likely to happen unless installation is botched. Running slightly lean or rich is hardly guaranteed to cause damage - myriad folk have been using their bikes this way for years without issues.
While I agree that running a completely straight-through pipe is not ideal without flashing the ECU or using an air-fuel modifier, most sensible people tend to run with one or more baffles, which seems to keep the fueling within a reasonable range (as compared to stock). You can tell if it's miles off from the change in behaviour of the bike when the new exhaust is fitted.

I called my dealer and they shadowed what nightic has said....they have never had a bike fail on warranty due to an aftermarket exhaust....

As for the zorst boy its loud and i love it....it does run a tad rich id say but they are a super lean run bike anyhow.... also the engine braking is nowhere near as bad and the bike just feels more freed up if that makes sense. I shall not get mine flashed as its a pcp so ill pop on old exhaust and send her bk at the end of the contract ready for my next bike or perhaps buy her and sell her privatly

Hi Matt,

I was wondering how the Tec exhaust is going? I'm very tempted to get one at such a good price and I like the look too, but the main reason is the hushed tone of the stock exhaust. I emailed Tec and the owner said that a remap isn't necessary if you keep the baffle in. I was wondering if you run with the baffle in?

Cheers

As I have mentioned elsewhere, my 2016 XSR700 came with a Tec exhaust, which I (and my neighbours) find too loud.
Contacting Tec today, I was delighted to be told that their "short, 6 hole baffle" should make it less anti social. Its in the post today and I will report once I have tried it.
I do have a standard exhaust, but fitting that will be the last resort.

I bought the TEC exhaust but found it too loud and put the original back on after a week. Just couldn't live with the noise. I knew about the quieter baffle but it would have to have quietened it dramatically for me to have kept it on. Shame because it looked great and was very well made, but sanity over vanity and so have to put up with the original ugly lump

How did the baffle work out? I'm considering TEC. I commute through central London every day so don't want anything obnoxious but definitely want to open up the growl from the purr it is now.

It didn't work out, not for me anyway.
It did take the edge of the standard Tec's racket, but still too loud if you need to be on good terms with the neighbours.

Oh really? That's a pity. As I think i may be in the same boat as you, really wanting to open up the sound a little but blow in any windows. What did you opt for in the end? Or did you stay stock?

I bought the bike with the Tec fitted and the stock exhaust tied across th back. So I refitted it and sold the Tec.
Very happy with the bike but may be selling it and make do with my old XT600E. I don't need the XSR's performance and the XT does all I need.

Hi mate,
Would you be open to sell the tec ?
