What's stock exhaust size?
Just a quick question, what is the stock exhaust size for the 3.1?

Well it's 2 1/4" on the 2.8. I'm sure it's the same for the 3.1.

That's wierd. Maybe someone swapped a stock v8 exhaust on your car, those are 2.5" right? I guess the only way to know for sure is to go out and measure it yourself.

Re: What's stock exhaust size?
I have replaced the whole exhaust with headers and a dynomax cat-back. I think it was all stock because the bolts were froze up, the muffler was about rusted through and the cat felt like it was glued onto the pipes.
