depends on the collector size, size of the primaries and your setup.. Each motor is different..Originally posted by raydog2533 View Post
Greddy is a nice header, but the collector restricts the horsepower..
DC with a 2.25 collector is a little better then stock..
DC with a 2.5" collector is pretty nice..
JDM Headers, really depends which one you get.. FGK has bigger primaries then the us spec ones, and range from 2.25" collectors to 2.5" collectors.. I got a few JDM Aftermarket headers I will be selling in the next few days..Header Whorage and Official Part out sale.

I have a Greddy Header but I think it might be a ver.1 because I compared it to my boi's H22 Greddy header and his collector size seems to be 2.5 while the collector on mine seems to be smaller. I'm guessing like the DC headers, there are two versions. :shrugs: The 2.5 collector is generally what alot of people go for because for a street N/A setup, it's best to match the exhaust with 2.5 inch piping so you won't be bottle necking/choking the engines performance for highend. Stock the H22 has smaller than 2.5 inch piping, but opening it to 2.5 definitely makes a impact on it's performance.
This is what you generally want to do. Header with 2.5 inch collector, 2.5 inch straight pipe/Hi-flow catalyst, 2.5 inch tubing exhaust.

Also, as you are in CA, you need to make sur that it has a CARB plate (CA smog legal) so you don't get into smog trouble...
I have a Greddy and it works well for me.Originally posted by Junior Smurff

Another way around this would be making custom tabs to fit your oem heatshield. That way the smog or po po won't even know.... This only works if your header bends don't stick out further than the OEM header otherwise the shield won't fit.
I need a custom turbo manifold built....
