I have Mac midlength headers with a Magnaflow exhaust. I'm wondering if there is an ORY pipe that I can buy that will replace my stock Y-pipe and my cat? Also the guy I bought my car from had some kind of 3inch off road pipe from Mac installed. I think it connects the stock Y-pipe to the cat but I'm not sure. Or does anyone have any other suggestions?

 

Check under your car and see what you have first. Mac makes off-road y-pipes for there headers, you just have to look on there site.
