Oh here we go again! Just get a grom. Then you only have 1 into 1 to deal with.

 

I personally think it looks wayyyy better. Less is always more for me.... when it comes to exhausts.

and yes there is some “science” about back pressure and higher torque.

but remember. Your bike is your OWN. Customize it the way you want.

 

I had an 09... wished I snagged the 10.


Haha.

 

Exhaust pulses. It’s not one constant plume of exhaust coming out, it comes in pressure waves of high and low pressure. The exhaust from 1 cylinder creates a low pressure pulse behind it as it exits that helps suck out the exhaust from the other cylinder, which then helps evacuate it further and helps it suck in more air.

Edit: It gets crazier with more cylinders. I want a tri-y 4-2-1 exhaust for my CB750, the exhaust with jetting is said to greatttttly increase HP.

Edit 2: Some has to do with harmonics on the exhaust too, pulses will reflect back down the pipe. Longer exhausts = better scavenging at a lower frequency harmonic = better low end. Shorter exhausts move coming on the pipe up higher in the rpm range.


Sorry, I like exhausts haha

@LocoLocal are you ready?

 

Go out and scoot!

 

It’s raining here... you guys still going?

 

What?! I think it rained for a little here, but back to high humidity and sun. I still want to go.
We were going to leave around 10, and expecting 1.5-2hours to get there.

 

Looks like it stopped but might rain later. I’m still down to go, getting ready now and planning to leave around 9:30-10.

@loosnut you coming?

What? No peppers?

 

You're the Devil, man.

 

A real philly cheesesteak doesn't come with peppers!

 

I needed the extra power of the 09.

 

Unfortunately I am out the favor I was trying to get out of got compounded. Only bright side is part of the favor now consist of riding the girls sportster back to my place and storing it. With the you can ride it whenever you want clause.

 

Or onions. Also optional.



But I like both on mine.

 

This.

Backpressure is not a thing you want. Its all about matching exhaust pulses for better scavenging as ^ said
