Thanks for the advice. I can go outside and measure but I looked on ebay and see they have several diameter Magnaflow X pipes. Which size do I need?

And MTX5, you truck sounds HOT!!! It looks good too! I have a 5 spd manual myself. There are aftermarket mufflers on my X and it does have a little tiny baby growl. I forget the name though. I will post the name when I get my X back from the shop. I remember its inscribed on the chrome tips. But I dont think the stock resonator has been removed.

This seems like a good mod and not too expensive.
