To good to be true

So in the website it says its a direct fit, however that is not true at all. The system came with a 2 1/4 to 2 1/2 extension pipe which is supposed to mate right up to rear car output. However this kit is for both 4.0 and 4.7 99-04 models. My 04 GC 4.0 has a 2.5 cat outlet so the extension pip did not fit. Bottom line, do not follow the installation instructions for the 2004 model year. Bring it to a shop, have them modify the dimensions and weld it in.
Good exhaust, Pain to install

I tried to install it myself. I successfully did it but the instructions were wrong and the pictures were terrible. I had a local shop weld it up and fix any of my mistakes. Besides the initial install, the exhaust is excellent. It is louder than stock, but won't wake the neighbors. It gives it the nice V8 growl the Hemi deserves.

Great deep and quality sound! I instantly noticed the H.P. gain. Mileage jumped about 1 gpm right away. Hoping for more when I stop standing on it, just to hear it! Definitely lube the rubber hangers when removing the old system. I did it by myself, on a creeper. Took about 5 hrs. Toughest part was getting the old system off. Very happy with the sound!
