Guys

I am currently running my set up with Stock headers that have been Ported and Ceramic Coated... Would there be a big enough power difference by swicthing to lets say EVOMS's K24 aftermarket headers?

How much HP do you estimate I am leaving on the table if any by running Stock heaers that have been Ported and Ceramic Coated?

Thanks

 

The comparison you need to make is with how long the headers are (stock are about as short as you can get), size of ID and smoothness of internal surfaces. For at least up to 700hp, stock ported and polished will be your best bet IMHO. My guess is you won't gain a thing switching out headers.

 

huge enormous gains, something you must do. you NEED these if not your leaving sooo much HP on the table.

 

Oak strikes again!

 

Will they still add a lot if your car is just flashed, exhaust, and EVO intake? Or, do you need to change turbo's, internals, etc to make the difference worth it?? Thanks.

 

You say you have a Protomotive turbo. I
would completely trust what they've told/
given you.

 

I'm running stock heads on my beast.

 

Dave, ur headers are fine.... more then fine.... ist been said many times that stock headers are good for 600hp... u have the good ones anyway....

Take Divirexxtreme example... he ran 10.6 @136 mph and still on stock headers... things that make u go hhmmm.

Yes, I think I will keep them the way they are!

 

What did Todd, Todd, or Rob (ScarGo) say?

Ported and polished on my STG2 ZC's with great results and Kevin's upcoming STG3 ZC's will use the same headers... Kevin
