The media could not be loaded. I drive a 2004 Jeep Grand Cherokee limited with the 4.0 inline 6 engine. Overall this exhaust system is great and for the money it was perfect for what I needed. My old exhaust system was rusted and had holes in the muffler which caused there to not be enough back pressure which ended up in the engine running rich. After thinking about it I decided to replace it with this one. For me it wasn't too hard to replace it, however I have some experience with vehicles and metalwork, I also had access to a shop, car lift, and plenty of tools. I ended up having to use a air chisel, reciprocating saw, a pipe expander, as well as a MIG welder to tack weld the pipes in place since the clamps that come with it aren't enough to keep it solid. So if you have no experience with any of those tools this might be a bit of an undertaking. If it seems like too much you may need to take it to a shop where they can properly install it, so just keep that in mind.

Another reason I have to say that I replaced it is because in all honesty I felt the stock exhaust made the engine sound lackluster for what power it had, so that is one reason why I changed it and I have to say I'm not disappointed. I also included a before and after video of the exhaust just for reference of look and sound.

Pros-
great deep sound
helped with my gas mileage
Improved my throttle response
Great value

Cons-
modification of parts may be needed
You might need access to certain tools and equipment
fit may not be exact

So I got this for my 04 wj 4.0 honestly sounds so much better. It's not a bolt on your going to have to get some pipe and adapters to get it on. But it's definitely a good deal. Sounds even better after its broken in! No mileage changes for fuel.

I used it on my 2000 Jeep grand lorado 4.0 I've been asked where did I get this exhaust overall it definitely gave my Jeep a new sound and a new look and great on gas

Love it, but had to modify it.

Quality parts fitment was perfect fit the first time, tubing is not too thin the whole transaction went smoothly love it, I'd Recommend This productto my family and friends
