Got this to replace an old system and hoping for an improvement in HP. Slight improvement in sound, but was not able to detect any improvement in HP. Looks nice with the dual exhaust appearance. So great replacement, with better sounds and appearance, but would not suggest doing it for a HP improvement.

I purchased a 2006 H3 this year with this exact cat back system on it and the droning noise in the cabin is terrible. People in the back seat give up on conversation. It actually causes headaches at times. Outside it doesn't sound aggressive or throaty. It just sounds like it should be silenced, kinda like a 4banger with coffee cans. Oh and a baffle came loose in the muffler so its got a nice loud rattle to add to it. Coincidentally I stumbled upon this product on Amazon while searching for a replacement. I certainly don't recommend this one.

Fairly easy to install yourself. With basic mechanic skills and tools can be installed in about an hour. A muffler shops charge is between $80-100. Looks good. No issues or rattles. Not overbearing or loud. A deep throaty sound at low RPMs but not loud at full throttle. At highway cruising speeds very little drone in the cabin. If you are looking for aggressive, this is not it. But if you are looking for a good sound and performance this is perfect

Went in easily, fit was perfect, sound is a little louder than stock with a nice tone. One one complaint, it does not come with the nuts needed to attach to the catalytic flange. Those nuts seldom survive disassembly.

Put this exhaust on my 06 H3 and it sounds amazing. I am probably costing myself more money because I always want to hit the gas everywhere I go.

Installed on my 2008 Hummer H3 with 3.7L. Nice looking improvement over stock exhaust. Sound is nice. Removing the stock exhaust is a little challenging and takes the most time since you need to get it loose from the rubber hangers (you will need some kind of lubricant) and you need to cut the exhaust with a saw to remove it as per the directions. After you get that done installing the Magnaflow is a snap. Glad I did it.
