My Arrow pipe arrived today, so naturally I installed it tonight. I ordered it from an ebay seller called acrmedics, I paid about $540. He was very helpful and communicative; seems like a good guy. It seemed like a good option relative to the Akro system. I have had Arrow pipes on other bikes, and have been happy with the product.
There are four options for the actual muffler. I went with the smallest, lightest, and likely loudest option, the GP2. It is finished in dark stainless steel. Finish quality is definitely as good as it gets. I hadn't realized there is a Ti option in the GP2 can as well. I ordered the additional baffle kit called the dB killer. That piece hasn't arrived yet. The kit includes a mid-pipe with an expansion chamber which replaces the huge stock chamber.
Install was surprisingly easy, other than accessing one of the header bolts which needs to be loosened to remove the stock expansion chamber. Arrow provides a new steel plate to cap the hole in the belly pan where the new pipe exists the stock exhaust location. It was pretty slick, actually. Everything was an easy fit.
I fired it up and it sounds fantastic. Better than expected actually; it really isn't ridiculously loud. It's just...pretty loud. It sounds like a proper motorcycle now! It was late, so I havent ridden it to get a seat of the pants feel for any performance changes. And, unfortunately, It will be a little while before I can get to a dyno. When I do, I plan to install the K&N filter and probably ditch the airbox snorkel have everything tuned.
So...what is the opinion on best tuning software / system currently?
Weight wise, the new system saved exactly 6.2 pounds.
You might notice in the photos one small issue; I don't have an exhaust hanger (yet). The pipe is intended to mount to the existing passenger peg bracket. All of the necessary hardware was supplied to do that. But, I have binned the passenger pegs, so I will be fabricating a little bracket to hold it. I realized that when I ordered it, but I had sort of forgotten until I slid the pipe on.
Ground clearance looks pretty good, but I wont know for sure until the next track day.
