Anyone have a pic of the OEM exhaust from the header back? In addition, has anyone simply cut off the stock muffler and/or resonator and welded on an aftermarket muffler w/o changing the piping? Also, what is the piping size?

 

Why would you cut off the muffler? There are after market mufflers that all you do is take of the clamp that holds the muffler to the pipe and basically un hang the can and hang the new one and re clamp.

mb2008, thanks for directing me to that thread!

I was curious as to what the entire exhaust system (from the header) looked like. If there's space, I'd prob weld an muffler closer to the header and cut off the stock muffler.

Know the piping inside diameter by any chance?
