I just got a 2005 2WD SE Auto. I dont want to spend a ton of money on it right now, but I would like to do something. I bought the drop in K&N filter and installed it. I want to change the muffler but use all the stock pipes. Have any of you done an exchange with a new muffler only? If so, what did you buy and is there any difference? I know the power will not be noticable, but maybe the sound?

Please let me know.

I did this exact combo on my 2000 Wrangler 4.0L and I liked the sound it created. Plus, I swear I got 2-3 more mpg. But again, I cant prove it.

Thanks for your help.
