I ordered it Monday. It is on a 4-5 week back order so I cannot give you any real opinion on the product, However I am absolutely under impressed with the fact my card was charged twice and it still hasnt been corrected and the salesman on the phone got multiple spellings wrong even though I spelled everything multiple times for him.
The second person I have talked to seems to be much better and has promised to handle everything as well as match the price for the presidents day sale they just announced so I was happy with that.
I know when I had my 5th gen camaro a lot of guys ran their products and never heard a bad thing about them, but this is my first time going with their equipment. I have used K&N and roto-fab before. Roto-fab was supposed to have one first of the year but still zero updates on that and K&N wont even respond to me so I went with this one
