This is True.

Any info if they are coming out with a high mount version?
.


Unfortunately, they said : "No plans at this time... to make a high mount. "

Yes, there is.

Also on the Slip-on as well.

Here's photo of the STREET SLAYER SLIP-on

I wish one of these companies would make one of their systems in full titanium.

Most of them feel like the cost would be a little too much for a R3 rider.

Even if there are some who would be willing to pay...... the vast majority probably wouldn't.

I'm liking the street slayer, I'm not a fan of the full length canisters on the R3. The stock exhaust size is fine with me and so far the Graves and M4's SS look like my favorites. Can't wait to hear the M4!

Looking forward to it! I just looked on the site, is the Street Slayer a full exhaust with headers? Or the muffler with a mid pipe? It says it eliminates the cat in the description.

Street slayer is ONLY offered as a Slip-on.
You "cut off" the Stock Cat, and then install the slip-on and midpipe.

Would a fuel controller such as a PCV or Bazzaz box be required (or recommended) since that cat is removed? Even then it is still at a decent price point. You guys have great pricing on the PCV and I think I'd add a QS at some point.

The PCV is not something you "Have to Have "
You can install a slip-on and or filter, and go ride.

But, normally most guys wind up getting a PCV to help their bike run better. Smoother throttle, more efficient.
The bikes tend to run really lean to meet EPA Emissions.

We will be doing all these mods on our R3 project bike.

Adding a quick shifter is a must for us.

Once you have used a quick shifter, it's hard not to have one on your bike. Specially with GP Shift. Nothing like CLUTCHLESS Wide open Throttle Shifts, entering onto the interstate, or leaving a stoplight. ;-)

I need this in my life, are you guys willing to deal at all on a package deal with say a full system plus pcV and the autotune?
.


PM SENT.

We will try and get this in your life. ;-)
