I’m trying to get headers for my g37. Can’t Decide on which ones to pick. I have looked at the z1 ones and the tomei ones too y’all know any other ones. How good at the tomei ones

PPE
fast intentions
Z1
Tomei

 

One big question is, are you required to pass smog inspection? That would eliminate the first two on the list being that they are long tubes. You would then need to go with next two in that order Z1 then Tomei. I have heard of to many issues with other headers such as DC and Stillen etc.... the install is a pain and or spendy so I wouldn’t cheapen out on them. I have a set of Z1’s headed for Jet-Hot, then install.

 

I have had DC ceramic coated headers on my G sedan for a number of years and many track days. With the Stillen exhaust the car sounds amazing. I have had zero issues with the headers, but any brand you get will be a bear to install. Not a lot of room to work with on these cars unfortunately.
