Is there anyone running this header? I received one in trade when I sold my turbo kit. I also have two other stock manifolds (one will be ported/coated) at my disposal. I am honestly not worried about longevity, as if it cracks I will pull and install the ported stocker. My question is, will it make any power increase, will it lose power, help spool, etc?

Thanks

I dont think you will see any difference. It will def. make the car sound different under boost, but i dont think you will get anything out of it, spool or power. Its a very nice product and will help decorate the engine though!!

 

My guess would be -10tq +5hp
