These cars don't have headers. What you could call the headers are cast into the engine block and dump directly into the precats.

Instead of headers you can buy Precat deletes or high flow precats, J-pipe then a catback.

 

Damn that’s weird af never heard of anything like that. If I do what you are saying what kind of sound would I be getting and would it give me any gains as far as power

 

A few extra ponies; that's about it; the cast in collector proved to be very efficient.

 

Do a search on "PCD" Pre Cat deletes or HFPC High Flow Pre Cats.

 

It’s commonly known as a j pipe
and then you can delete your cats as well.

You get a slightly noticable tone from the j pipe. But barely noticeable performance wise. Can’t speak to the high flow precats or pre cat deletes tho.

Most of the vendors on here sell them. Take a look
