I don't get it why would you sell them on ebay for 279. and on there site for 319.??
The chance there could be a bidding war and they go for higher than what the sell on the site?
Sometimes a manufacturer won't let businesses sell their product below an authorized "floor price" and eBay is a great way around that since it's not done through the retail side of your store in some cases.

I have FRPP stingers.
I dont know what you guys are calling drone but there is sound while cruising, but nothing like stock manifolds, 2 chamber flows and O/R hpipe...
Honestly they're not loud enough, and a couple people were telilng me that they would be loud and have drone when i first got them... I'm thinkin they were old middle aged men...![]()
Well, I just turned 50, so I guess that puts me well into that category![]()
