s550 headers on a s650

[Rush hour 89]

stainless works headers previous headers from the 5th gen work on the 6th nothing got re designed

lethal has kooks headers that are listed 24+ gt then an off road set (15-24)gt

I called American Racing and was told 5th gen won’t fit the head flanges are different…..

Anyone put a 5th get set on yet? I have ARH long tubes sitting in my room from my 18 not trying to spend 3k on kooks

They have a different bolt pattern on 1 side… the new lethal headers now have both patterns on the flange.

Ok thanks that kinda blows. So stainless works from the s550 work …

Only if they redesigned the flange post 2024.

I know some guys on you tube say they picked up 30HP with the Kooks long tube headers without any tuning. I think that's pretty good HP gain not sure if they have deleted the resonator or not H pipe or X pipe.?

Hey there!

Sadly, simple answer is it will not work. The flanges will not allow it to work properly. The ARH would have to be swapped out, unfortunately.
