Is there a metal gasket that goes in between the helix down pipe and o2 housing? I dont ever remember there being one..I havent used one ..I had a friend think that was weird that i didnt have a gasket there...do you helix DP users have one or not?

 

There is a donut gasket on the o2 housing. If you are going to an aftermarket o2, then take the gasket off the stocker.

 

i guessing it works with the dounut gasket alone well

 

yeah i have the ebay 02 connected to my helix dp with just the dounut gasket...so i dont need a metal gasket ?

 

ok doesnt look like it would need one...lined a 3 inch gasket on it..doesnt line up lol
