id love to put up some of my receipts but im not a self centered ar$ehole who thinks im better than anyone else. theres alot of us on here who have splashed thousands upon thousands on our cars so i think youve got it all wrong mate. i think you have just read the sales pitch about these manifolds and got a little hard on over it. then came on here asking folks honest opinions and got all worked up when they tried to give you advice. i honestly dont care whether you buy them or not as its your money, your car, just dont get all snobby and up yourself
