4 inch to 3.5 dp for atr headers.


Going to be buried in this.
Aug 25, 2002
Well I bought a new turbo and the it has a 4 inch outlet. I have atr headers. So I had to make a dp for my set up. It still has a/c, so room was tight. I was able to install and remove it without taking anything else off. 304 SS to a full 304 ss exhaust. It was on the car for about a year now, but since I have the engine out I wanted to post some pics for this section.
