Yup, pretty much just replaced the stock with the Magnaflow, had to add a small section of pipe on one side since the Mag is a bit shorter but other then that thats all it took. Muffler ran me about $70 bucks and I had my local shop weld it up since i dont have a welder which cost me $50. Add in the $15 tip and all in all it cost me $135 total. Im sure you could do it cheaper installing it yourself and probly find the muffler cheaper but ive recently caught the "jeep thing" and now im a happy compulsive buyer
God i hope i did the math right
If you want ill post the Part number for the muffler, i think Magnaflow is the way to go if you do a lot of trailing. Its Stainless, has a lifetime guarantee, and is quiet when you need it to be.
