Crazy LOUD Yamaha R3 Exhaust Sound

Startup, revs, fly by, and quick downshifts from a 2015 Yamaha R3. This R3 is equipped with a M4 Street Slayer slip on aftermarket exhaust system, so it sounds much louder and more aggressive than stock.
Get this exhaust! amzn.to/2V7bLsn

Now i know what i will get

[@Everendlesss]

I got this exact setup as my first motorcycle, except a 2017 R3. The M4 decat slipon is very loud which is what I was looking for. The bike definitely doesn't sound like a 300 class motorcycle anymore. As for a first bike, I am extremely happy with my choice. Very inexpensive payment as well as insurance.

I love crossplane Sounds 👍👍, Best crossplane u can get on a cheap bike R3 & Mt03

[@josephkluck9526]

Aren't they parallel twins though?

[@Ello0999]

@@josephkluck9526 yep R3 engine's parallel twin and it sounds kind of like crossplane when u give it some throttle, If u do own a bike which Is it?

[@chrisp.5272]

It’s not a cross plane, it’s a common 321cc Parallel Twin with a 180 degree crank, not a 270. But it still sounds nice with the right exhaust or at high RPM’s. The MT-07 and R7 though has a bigger Parallel Twin at 689cc with a cross plane 270 crank.

[@The_Sniper27]

What kind of exhaust did you put on bike?

[@zxr250]

It's an M4 Street Slayer. It says in the description.

[@hehehhe5461]

[@pharoahamunra]

I like speed to yay.

[@jraybay]

[@Ramasenirama]

Look faster rather than zx250r

[@darrynberry8124]

It is it’s a 320 cc

[@bernardo290499111]

Must be a really nice bike overall, but it sounds horrible, ive seen it in person too and its no different, sounds like a straight piped food delivery bike like a CG 125cc

[@MrBeroZgar.]

Benelli 300 sounds better than this
