"Ok... so I've seen a lot of ppl with jeep wk's with the 3.7l v6 asking about what exhaust system to buy. They want an aggressive sound but that's not too much. This is perfect! It sounds really nice at low rpms. I got it for 253 from autoanything after the $25 rebate. Can't beat that! Look no further v6 jeep wk owners. This is perfect. The one thing i did notice was my gas millage isn't going up as high. I would average 22 miles a gallon before, i can still get up that high but it takes longer" —Christopher C from Kiowa, CO bought a Gibson Exhaust Systems for a 2005 Jeep Grand Cherokee, 3.7L V6.
"I researched several different sites and forums to ensure this exhaust was a good fit for my Grand Cherokee. Unfortunately, the install failed to live up to its standards. This exhaust was 2" short of where it was supposed to end up post bumper. Instead, the exhaust ended flush with my bumper. I immediately phoned Magnaflow from the shop I had the exhaust installed at. They asked us to do several measurements to rule out a defect in my order. All of the measurements were accurate. The Magnaflow rep stated he didn't have an answer for me but that I could return the exhaust for a full refund. Since my original exhaust had already been removed, this wasn't an option. Luckily, I had a 3" piece of stainless pipe, 2.5" in diameter. This is just what I needed to cut the Magnaflow system post-cats, weld in the new piece and adjust the remainder. It worked. On another note, it sounds great. Not too loud and levels off at higher speeds. I just wish Magnaflow was correct in its labeling of this kit as a good and proper fit for my Grand Cherokee." —Michael P from Allen Park, MI bought a Magnaflow Exhaust Systems for a 2005 Jeep Grand Cherokee, 3.7L V6.
