How do you guyz avoid your header bein scrape or shaved off at the bottom? Mine lookin worse and these are brand new header too damit......Does it affect the flow if its scrape or shaved off underneath? Maybe my ride is too low?

 

Your ride is just too low. Notice how most functional suspension setups arent on the ground. Yes it will affect flow.

 

The srapes and dings will affect the flow, but you can go to a machine shop and they can fabricate a plate you could bolt on. There's a company that sells them already, but I don't remember where I saw them(not much help). The desigh is simle though. From the side it basically looks like an "L" laying down. think about it.
