Thinking of getting a slip on exhaust for my 06 F4i. Can I get some recommendations as to brands? Also, how hard are they to install? Do they indeed jsut slip on, what about that oxygen sensor thingy?

Thanks

As for a brand....you're just gonna get people's opinions. They all have a different tone on them.

Here's a bunch of sound clips of mufflers on a R6:

A lot of people go for the Two Brothers exhaust....it's got a deep tone.
I had a Micron, but just put on a Yoshimura and I love it.


They do literally "slip on." It's a VERY simple bolt on procedure and the exhaust systems usually come with instructions, but it's really simple to do. Like a 20 minute job if you take your time.
The stock system unbolts in about 2 minutes.

As far as the O2 sensor....only the California models have that. So if you have a California bike, then you gotta order/find a exhaust system that is for the California model (like Yoshimura or Two Brothers offer) which has the bung for it.
And if you don't have a California bike, then you just need a regular exhaust.

I'm not sure but maybe on some exhaust brands, they all have the bung but they provide a bolt to block it off in case you don't need it....not sure about which brands though.

check out pipe city (http://www.pipecity.com) they have tons of exhausts to choose from @ killer prices. free shipping as well. i put a two bros carbon c2 on my 02 f4i, sounds great! as for the o2, i got an o2 eliminator, it was $15 from pipe city.

Did you guys just put the pipe on and go? Did you have to do any other adjustments, fuel injection, etc?

I have a 2 Brothers carbon fiber high mount. You can see pics in my gallery. I really like the looks and the sound is a nice deep throaty rumble... Just my $.02 worth!
