    I am with Bio on this one...not really happy with any of the headers out there because of leaking and fit issues...yes its easy to pay for better clamps and weld in a new flex...but then you have to deal with the o2 issue on SD headers...that is the original reason I bought the DP is because there is no leak issues and they fit like the stock one does....the main reason I bumped this thread was because I already have the DP and don't really feel like going through the hassle of selling it then buying headers...so if don't loose that much WHP from just adding a Plog to my current setup I am ok with that...I know everyone says don't do it but I deff am going to try and run a cam with a Plog Dp combo

    Hey that's cool it's your car but I don't know why if you went through something as complicated as a cam install you wouldn't just mod a set of headers up quick and be able to run alot more timing with the increase in flow.

    Because it isn't just about the timing...just because you increase flow doesn't mean the car was making 2-3* less than stock timing and knocking from the factory. All headers have done on some cars is put them back to factory tip top shape, and then...you're running a stock pulley on a car that makes 5-7psi with manifolds and a poo-poo DP setup...and expect what...3-5psi after the headers? Then you need to pulley down to compensate the loss of boost from the flow to get back to square one...and then wheeee, KR on a smaller pulley.

    It's a fun cycle, isn't it?
