I made the mistake of buying one of these recently, I shoulda spent the extra 15 bux and got a screamin' eagle. The Thunderstick is a piece if scrap from a muffler shop with an HD clamp on it. The end that goes on the header isn't even slotted so it can't tighten up. Both ends of this pipe were ragged and covered in burs from a saw. The insert in the box it came in said I should cut up soda cans to make a gasket so it doesn't leak. Also beware of user Kwik_bay on Ebay. If you must buy from him look at his feedback very carefully and read the item description very very carefully, chances are you aren't getting what you think you are, that's probably why he has a no refund policy.  I reported this item to Ebay but I'm guessing I'm out my 50 bux, but I thought I'd let everyone know so they can steer clear.

people like that are bad for ebay and for the motorcycling community who are mostly goos honest people like you obviously are.
