I purchased this exhaust from Karstens and received it in 3 days.
I finally got around to putting it on today. Let me start by saying, I had a heck of a time getting off the existing exhaust.:gaah: There was alot of :cus: and alot of that :cus:. I am mechanically challenged and lacking all the right tools which adds to the frustration level. That being said, i did eventually get it off without injuring myself or the bike.:roflblack:
Installing the new pipe was actually fairly easy, but trust me, the :cus: was still flying. Slid the pipe over the spyders pipe, tightened the clamp, put the bolt on the hanger(same exact setup as original) and was ready to fire it up.
The first thing that came to mind once I got off the ground to look at it was, that humungous thing hanging off the side of the bike was gone!! Instant Jenny Craig, i'm guessing around 25 lbs of weight loss?
OK, was ready to start it up, hoping i tightened everything enough. That will now be my new worry until i take to my mechanic friend and have him check it....

I fired it up and it sounded just like the video karstens posted, it was awesome. No more sewing machine sounds!! It is also louder than the OEM, I have nothing else to compare it to. It idled very nicely for 10 minutes, revved it a few times and was ready to take it on the road.
Took it for about 15 minute ride, just waiting for it to fall off:roflblack: or something. At cruising speed I thought the sound was good, louder but still could listen to the radio. When you give it some throttle, it sounds like a beast although nothing like the HD that passed me. The bike also seemed to have some more jump to it esp since I was 2 up. I'll ride later by myself to see how it feels then.
All, in all, I would say i'm happy with the pipe, the price including shipping was fine, it appears to be made well(welding was fine) but like anything else, time will tell. I like the weight loss for sure, what seems to be snappier takeoffs and if i get a few extra MPG's, that will be good also.
:2thumbs: Karstens!!!
