Northeastern Exhaust | Stainless Steel Performance Cat-Back Muffler Exhaust System Kit Compatible for Jeep Grand Cherokee 1999-2004 4.0L 4.7L | Free Clamps Included

Love it, but had to modify it.

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 soundhelped with my gas mileageImproved my throttle responseGreat valueCons-modification of parts may be neededYou might need access to certain tools and equipmentfit 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.

Easy to install and fit great. I did not have to trim the pipe between the cat and the muffler on a 2004 Grand Cherokee. I did have to trim the rear bumper to accommodate the exhaust tip, but no big deal. I think it has the perfect tone to it now. Not too loud, but still makes a statement without resonance in the cab.

V8 4.7 u need to cut to fit supplied extension pipe and weld.

Went on with ease and really made the V8 sound so much better

Doesn't fit the 2002 jeep grand cherokee v8 without additional pipe. sends you smaller pipe then stock to attach onto the stock y pipe.

2000 Jeep Grand Cherokee great look and sound. Took to local muffler shop and had them weld it together and remove resonator for deeper sound.
