M4 Yamaha FZ-07 / MT-07 / XSR700 15-20 Carbon Fiber Slip On Exhaust

Great m4 slip on exhaust. Sounds amazing, looks great and great quality. Best deal.

I was worried this would be harder to install than it actually was. The biggest issue is the welds you have to cut by can vary on how far up they go. and if you have a thick bead in between the two headers it can be tricky to separate them without damage. I would highly recommend having something to clean up the cut, I used a Dremel. Lastly, its LOUD, if you have angry neighbors, or live in a quiet place, keep that in mind.

Just took a ride on my fz07 after riding a few thousand miles with the stock exhaust and man it is like a totally different bike, should have done this from the begging. Still havnt tried it without the db killer taken out. I think its plenty with it in. Will ride more and hope it all holds up. My only negative is I didn't receive any high temp silicon to put on the headers, not a big deal but for the price you pay. $8 tube of silicon would be nice. Install took about 45 mins. Well worth the money in my opinion.

Sounds incredible and plenty loud, highly recommend if you dont want to spend the money on a full system

If you are reading the reviews then you're probably thinking about getting this exhaust for your bike. I want you to STOP THINKING AND GO FOR IT!!! I promise you the exhaust will put a smile on your face! Loudness? It's much louder than the stock and I think you don't need to remove the db killer. Sounds amazing even with the baffle in! I also sent an email to M4 company and they said that I should be fine without a tune or ecu flash! I'm happy with the M4 exhaust and I recommend it! You can't beat that price! Stop thinking and buy it now!

I have a 2019 Yamaha MT-07, and this was exactly what I was looking for on my bike. My dad and I installed this slip-on, and it took close to an hour to complete. No video can do the sound justice - it sounds mean as hell!

I thought everything would be there for the installation but the high temp sealant for some reason was not included so I did have to obtain that on my own. Aside from that everything was delivered on time and in great condition. Fits great, looks great and sounds good.

Simple install took only 90min and required no additional ECU flashing, mapping or power commander. Light weight exhaust dropped 15-20lbs off my stock FZ07. Sounds deep and throaty like a cruiser with a gentlemanly volume at idol. Big “braaap” if you need respect in traffic. Excellent product, no need for full exhaust at double the price.

Hands down my favorite exhaust for the FZ 07. I've heard several in person and this one gives it a mean deep growl and some awesome backfire.
