I just installed a Yosh TRS slip-on (CA version) on my 2005 F4i. The muffler had the plug for the oxygen sensor and everything installed smoothly (20-25 minutes) and turned out perfect. Not to mention it sounds amazing!

Do I need to adjust fuel mixture or "remap" or anything after installing this muffler?

 

Our bikes are running lean from the factory to help pass emissions testing. You make it worse when you add slip-ons and high flow air filters. It's recommended to remap, but you can get by without it. I did it to keep things running optimal and you will notice a difference in power. It'll cost you about $300 for the PC III USB.

 

Is the PCIII something that installs and stays on the bike or is it something you connect to the bike just to adjust the settings?

How does the PCII work? Is it effective?

 

It's a programable box that you install. It's plug and play... you disconnect the plugs on your fuel injectors and the PCIII reconnects them.. Very easy.. It works and you'll notice a difference with a stock map.

 

It stays on the bike, normally people will run the wires under the seats and put the box into the back seat trunk

 

Cool. I'm going to pick one up as soon as I make time.

Thanks.

 

as i understand it "slip-on" means you cut your pipe, right? "bolt-on" means it bolts up in place of the stock piece?

i've been looking at yoshi's and they have a whole bunch of different ones. i'm looking for probably the quietest one. anyone know which one that is?

 

You don't cut the pipe....

You will receive a new mid-pipe with the slip on and it slips on like your old one did. Most slip ons also use springs to hold them in place, my 2bros Mh2 does bolt on.

 

Congrats on the new exhaust. I have the same thing on mine and I don't have the programmer. Seems to run great to me.
