I would wait for a group purchase to come up, I saved 40 bucks on mine doing that, and I love mine it works great. IT made the car louder but not as much as I would have liked, after headers of course its like NASCAR-a wee bit to loud, but since its electric I can adjust it. If you want it loud all the time just save yourself money and get the manual one and just leave it uncapped, then in the future if you want an electric one just get one, as it will bolt to the manual one already on the car. Its hard to explain, so look at some vendors pictures and you will see why it works, and when you order the manual, ask to make sure it will bolt to the electric one. I haven't seen any that don't but just to be on the safe side. you could also just cut the muffler off, this would give you a much louder sound, but then theres no way to reduce it like you could with the cutout.
