I have a question concerning the Greddy header. It is designed for the H22 but will the SH unit affect an install on it.

 

if its for an SH, you should be fine,
if its for a base it wont be long enough.

 

so far ive come up that the cat is going to have to be relocated.

Thats about all the info i really needed thanks.

I found some old posts searching, but there is no pictures in any of them, mabey they are just out dated, IDK.

 

The catalytic converter does not need to be relocated. If you want to install the header, you have to take it to the muffler shop and add approximately 5~7 inches to your current exhaust line to accomodate the length of the SH headers. Keep in mind that there is a possiblity that the header (the bottom piece) might rub the ATTS unit
