So I just installed the Yoshimura Y series exhaust available directly from Yamaha and it sounds excellent for an exhaust with a catalyst in it. I didn't want it to sound too loud and I couldn't be happier with the result. It has a removable baffle that I left in, so it could be even louder if desired. I haven't installed a fuel controller yet, and the popping is very minimal while engine braking. I have been looking at an ECU Flash Tune kit from Velox Racing, but I don't know that I need it. I am going to try to make a YouTube video of the sound for other XSR700 owners, but take my word for it, it thumps.

The 1st pic on the left is before it was ridden and the 2nd pic on the right is after a few days. The headers have changed into a nice bronze color.

At a Yamaha factory demo, I rode xsr with same pipe and have to agree about sound. It gave bike a little sound without being loud and when cruising down highway it quieted down, just what I was looking for.Hope to get one this summer.

I kinda wish there was a video that I coulda listened to it before I bought it. I listened to almost every other aftermarket exhaust on YouTube, but there wasn't one for this Y series. So I took a chance and used my 90 day 15% discount at my local dealer, and ended up loving the sound. The twin cylinder bikes make a nice thump vs the triples and 4 cylinder variants. Im not one of those who wants a lot of attention, but I want people to hear me if I am in their blind spot. I am sure we all agree that the stock exhaust is just too quiet :wink2:

Nice! Definitely recommend getting an aftermarket air filter k&n or dna, and then getting that ecu flashed. i am not sure, but the price of getting the ecu flash kit, installing, trying to find the right map, - you might be better off taking it to a dyno shop where they will flash it for you. (correct me if i am wrong anyone)

I considered the kit too but i dont think i would be flashing it more than one - unless i got it wrong had tried again. whereas the dyno shopp will be able to get it spot on for you.

Also the ecu flash gives you the option to change the engine breaking - as in reduce it. should make for smoother deceleration and you can also tkae your hand of the throttle whilst moving!

I hadn't thought about that. I'll have to see if there are local shops that dyno motorcycles. I just ordered a K&N air filter.

I contacted Velox Racing and they told me the ecu flash kit is the exact same one for the FZ/MT-07 bikes. So I figured finding a map for a similar FZ-07 wouldn't be a problem, but I haven't looked yet admittedly. That is kind of the reason I came here in the first place. To see what other XSR owners are doing for tuning...

Thanks for the review. Can I ask what make your radiator guard is? I don't want the Yamaha one because it's stainless and the R&G has a logo on it.

Anyone have luck using the flashtune kit and akra ti race exhaust? Just curious about tunes that are available for it before I buy it.

I wouldn't flash the ECU if I was you. The Y series is already setup to work properly with the stock ECU. By flashing it you will not only loose money and probably ur warranty but also you engine braking will be reduced which will make the bike more dangerous..

Robzilla, you might look into the "Booster Plug", which tricks the system for a richer mix. There are a couple youtubeos on it, also same for MT07 of course, Brogue also sells it.

I like the exhaust but too rich for my blood. I think it's just loud enough. the others I have heard are way too loud.
