I just rebuilt my engine and looking for exhaust options. This is a camper van so I’m not looking for wheelie popping power. Building it for mpg as much as possible. Hoping to get 16-18 but who knows.

Do you guys think I should look for long tube or shorty headers. I’ve seen both for sale and researched the pros and cons of each. Was hoping someone on here would have some first hand knowledge to share. Thanks!!
