As some of you may have read, I have finally run 3 inch pipe.
I went to one shop and the man behind the counter didnt want my business. He informed me that what I wanted was not necessary as several of you on this forum have said.
After some looking I found Custom Muffler in Lafayette, La. I explained what I wanted to do to him, and he too was questioning as to "Why?", but said that he
could do it with a bit of time and patience.
the result:
I have not felt the loss in bottom end torque that I was told that I would feel. "the 4.0 likes a little backpressure" is what I commonly read. I have found the opposite to be true.
I had been getting between 11-12 Mpg for the last several months, and since I put the spare on the roof rack the transmission was downshifting up every overpass.
First tank results with spare on roof, and 3" exhaust
14 Mpg. no longer downshifting up overpasses, and lower underhood temps, no check engine lights, no stuttering, no stumbling and a big roar! So far I love it!
I'll keep you posted on the Mpg to make sure the first tank wasn't a fluke.
