Ran into a proplem unbolting my stock EXUAST HELP!`

[TheRealist]

Well i just bought my car about 6 months ago and decided to put a 3 inch cat back exuast, so i ordered a Greddy Evo Exuast Bolt on, and it seems my catalic converter was either replaced and welded or i not looking in the right place to unbolt it.

Also whats the senser thats in my exuast as you can see in the pics, and do exuast that bolt on come with that senser hole??

The cat should be able to be unbolted from the front and back unless as you said it was welded on. The sensor is the rear o2, but I am not sure what aftermarket exhausts have the hole for it.

If the convertor was welded in, you'll probably just need a sawzall or something similar to cut the pipe somewhere. The sensor in your exhaust is an O2 sensor.

My Thermal came with the hole for the rear O2. I would think any exhaust from a quality company would also have the hole.
