Worked great on my 2008 Jeep Liberty KK. Hardest part of the job was removing my old exhaust and wiggling the new one through into position. But as long as you know how to use a reciprocating saw and some wrenches than this will be an easy job. I'm pleased with the sound. I wanted something just a little louder and "better" than the stock. This is just that, a little bit of growl but not obnoxious. I wouldn't mind it being just slightly louder but overall I'm happy.
Packaged very good, pretty easy install, and sounds darn good.
Loved it really easy to install and sounds great just wish it had better looking hangers can see 2 of them fron the rear and they don't look so great
This was the easiest install I have ever done & it sounds great
I was excited about the addition of this exhaust system. It completed my performance upgrades and now my F150 sounds great going down the road.
NO DRONE in 4-cylinder operation! ('09-'10 Chevy/GMC 5.3 V8). Plenty of RUMBLE.
GREAT price on an excellent exhaust. Why pay twice as much on others? I'm VERY happy with this system, looks great, easy to install and sounds fantastic. And it really opened up the midrange on my 06 Tacoma with the 4.0 V6. Two thumbs up!
The quality is very high. Stainless steel components with band-type clamps for easy installation, adjustment, and removal. It sounds real nice. Not too loud and no droning. I gained about 1.5 MPG average on highway driving.
