aFe Power Rock Basher 3" 409 Stainless Steel Cat Back Exhaust System Reviews

The exhaust seems well made except for the cat side, where the pipe is supposed to widen so it fits over the stock pipe section after the cats but it is the same exact diameter so it does not fit. I had to take it to an exhaust shop and it is not "stretchable" so they had to cut that section and weld on a custom-made part, defeating the whole purpose of buying a "plug and play" exhaust. Whatever they welded on had to be mandrel bent and it caused overheating so I took it back and they redid it, is now fine. A hassle. Not recommended until they fix this issue. If that issue is fixed, I would give it 5 stars because it sounds awesome and provides excellent clearance, especially when the jeep articulates.
