Maybe Danz's cousin is not into that car crazy to buy something that is more than 1k juz to increase the power. Or maybe he's just searching for a lil more power to climb the hill or whatsoever.
Why dont we suggest a better piping flow for him? just my 2 cents
I don't know Danz's cousin or exactly how keen he is with cars.
All I know is, personally I will not put any gimicky gadget, no matter how cheap, into my car on the blind faith of dubious promises of performance. There are too many unknowns with this thing in terms of what it will do to your vehicle, both good or bad. Sales talk is sales talk. I have heard a lot of them, from people peddling magical snake oil to dragon's teeth.
Call me conservative or prudish, but I like my car, and I won't feed it with stuff that don't already have a ready endorsement from the industry and community.
But hey...it's his money and his car. He risk what he wants.
