^^^ i dont get it

Running large primary headers on a stock L36 N/A engine will kill your low end torque.

so i shouldnt run this until i get a top swap right?

You can but you won't see the gains you would when it is S/C. No one is stopping you lol but IMHO I would just wait and do it when your already stressing and pulling hair doing the top swap :p hahaha

I would strongly advise waiting to do the headers until you do the top swap.

Doing it now will kill your low end torque and besides, the install will be 1000x easier if half the motor is missing

yeah thats what im going to do im trying to research what i have to weld and stuff thanks

ok i read every topic about PS headers and in conclusion all i ahve to do is weld the ypipe on all side and thats it?And i still dont understand the whole EGR thing

The EGR tube doesn't fit in the hole in the headers. You will probably have to delete it.

how do i do that?

Putting pennies in place of where the EGR goes into the headers and LIM, and deleting the codes in the PCM.

is that the only way?
