HI, Just purchased 92 400 sc

Would like something less restrictive

can you go over your recommendation again (no Headers)......and will the changes affect engine lights and sensors?

Thank you Mitch

Hi Jbbby. I’m original owner of 98 SC 400 and found your post. I’m in the process of making many of your modifications. Appreciate any additional thoughts. I see these are older posts and curious if you have any new ideas. 
thanks
