cheap and fuel efficient
My first post here on JK forums so excuse my FNG ways. 
So after searching high and low about what kind of mods I could do to my jk four door to squeeze out some extra mpg (especially after a 2 in BB and 33 inch muds) I decided to keep on the cheap and try slapping on a new muffler after dropping a k&n filter.
So I got 2 mandrel bent 90's and a cherry bomb turbo 2 muffler, two hours of welding and cutting...
I'm getting about 2 mpg bump in highway mileage..
Not bad for 2 hours on a saturday afternoon and all told $50 bucks...
If you're not looking to get a huge boost in power or loud ricey exhaust this is a great mod... I'll try and post some pic's

yep just a tad bit more growl... it's actually the reason I went with the cheapo turbo muffler I heard a clip of it on you tube on a minivan the same 3.8 that's in our jk's lol it sounded good so I thought what the hell sounds great to me..
don't laugh it's really not that bad sounding

it's funny right after the install I drove it around running errands with the top down and it's actually pretty pleasant not loud at all think of that clip but softer remember that mic is right on the exhaust tip
