Not sure. I cut off the muffler like you, didn't measure the diameter though. It sounds awesome, am I right? I love it, way louder than a fm40 or something.

But I was warned that the lack of back pressure will burn up the valves. Haven't researched to confirm, so of anyone knows if that's true, please let us know.

Try 36 gal of diesel.

Or even worse, the 225gal (and that was @ 5 bucks a gallon when prices were really up there) I used to put in my Volvo Tractor before I entered the Air Force.

I've had my muffler off since I bought it basically and you are the only person who I have heard say that. Im not really sure why it would burn up the valves? It doesnt drop that much pressure. The exhaust is still going through 3 damn cats.

But I know Im never going to put a muffler back on it. It just sounds to damn good. Right now it just dumps under the car, but I will be extending the stock tail pipe to fit the gap of the muffler. That should raise back pressure a little bit.



Ive never really heard on any car that cutting the muffler off would burn up the valves. But if there is some proof or something then I would believe it!

Well Im going to trust a fellow member who has done it, over some words through the grape vine that were given to me. I agree that it sounds amazing and the last thing I want to do is throw something on to quiet it down

Bought it!! 2001 Larado Select-trac 4.0 Stock

Still have my 93 Explorer 4x4 and so very glad that with this purchase i could find as good of a knowledge base that I have enjoyed with the explorerforum site.

Really liking the purchase so far. Except that a chain smoker owned it before me.
