My Staintune came in yesterday and I installed it this morning.
The sound is superb and hearing it while I ride is awesome.
I can't wait for a chance to roll onto the freeway and see how it sounds at higher speeds.
When I have time I'll take a video of it and add it to youtube, I'll add the link to the forum.
Swapping them was easy, the only thing that perplexed me was one of the steps on Staintune's fitting instructions.
Step 5. Unclip the servo motor cable at the point it attaches underneath the bike, leaving the cable attached to the standard muffler.
It has a picture but it is hard to make out what is what with the quality and it being in black and white. It does look like something is connected to the stock exhaust though but there was nothing connected to my exhaust.
I didn't really worry about it and continued with the staintune, just wanted to mention this to see if Scoobynut and whoever else has already got theirs and installed it (I can't remember who it was but I know someone else on here has a staintune as well) noticed this step at all.
There really was nothing to it when it came to putting the new staintune on, just making sure to align the hole with the mounting bolts underneath the passenger pegs.
Riding around town a bit doesn't feel that different, torque wise, but the sound does make it a different experience. Hearing the exhaust get louder as I roll on the throttle
I think my heat guard is now in a different spot though, I don't remember my heel hitting it where it does now with the stock exhaust on, but I'm not complaining.
This slip on was worth every penny IMHO.
Like Scoobynut mentioned a few weeks ago, the chrome is REALLY nice and I like the appearance of the bike with a shorter/smaller exhaust.
