What's up fellas. Felt like a long winter.
My question is about the f3 headers. I see them all over eBay but I wanted to know if there's a difference between the 1s that join side by side and the 1s that join up and down. I don't think the shape matters but you guys might have the facts

 

Can you provide pictures of what you're referring to, or a link to a photo showing the difference you're speaking of ?

 

Sorry to make you look. But if you go to e bay there's two shapes to the headers. Some when all 4 leave the motor and bend to connect to 2 go 4 across or 2 side by side. Even aftermarket has both. That's why I didn't think it mattered But if there is an advantage Id like to spend the money on the better
Mine as of now just has a little dent and usual rust

 

They are usually just different in design and how they wanted them to perform. I had a set of Leo Vince that had a lot of separate pieces and when installed really interfered with a race lower. The Hindle set I have been using leaves plenty of clearance.
