Easy install good fit

I bought this mid pipe about 3 weeks ago. On the install i had a little trouble with fitting the mid pipe to the headers. Then i stopped relaxed a minute and tried again. A perfect fit. I was just a little excited and in a hurry. I havent flashed the ecu yet. Infact buying the power commander v is actually less expensive so i got the pcv. Now i need to have my 2016 R1 dyno tuned. A little pricey but the mid pipe along with the yoshimura alpha t muffler and the pcv has added better sound and way more noticeably it has added speed even without the dyno tune. Cant wait to get the dyno tune to see what it will do then.

Worked out well

I installed the titanium version on my R1M and the tube on the left side is within a millimeter of touching the oil-pan. The stock silencer fit perfectly and isn't super loud. Looks great and lost lots of weight. I haven't re-flashed the ECU yet as recommended by M4. But did install block-off plates to reduce back-firing.

Works Great fits weird

So ive done multiple mechanical things on bikes for years now, not a certified tech but very good with my hands on an engine.

I got this product in and it looks awesome! Feels great and eliminated a good amount of weight removing the cat. Installation was a bit tricky, with my GYTR slip on this mid pipe was having issues sealing up properly where it connects to the header, I got some exhaust puddy paste stuff and sealed it up with that but have had this pipe off and on about 4 times trying to get it set correctly still doesn't fit 100% but I love the sound it makes and I fixed the very very tiny leak. gave my bike some more HP and torque. I recommend this option over the more expensive products for sure.

M4 Link Pipe

At the time of purchase i was debating if i should get this link pipe, the main reason was because it was not designed for my bike. I purchased this for a 2017 Yamaha Fz-10. Worried that it wont fit, i could not find any information on the internet. In the end it turned out it fits great, looks great and it fits bike well. Install was very easy, just be careful not to ruin the black finish, scratch it up, if you but the black finish one.

Q: If I installed this cat eliminator with stock mufflers on my 08 R1, would it be necessary to have the bike retuned, only reason for mod would be to cut down on heat

A: As long as your Yoshi slip-on mounts in the normal OEM location this will fit it. I cannot find a lot of info on yours so cannot tell you for sure if it uses original mount location.
Q: Not sure what this costs 2-500. Please advise thx
