Great value
Size: Single
Very few affordable cat back systems available for my 2004 4Runner Limited V8. Gibson system arrived early in good condition. Appears to be excellent quality. Had install directions. 2/10 install difficulty. All mounts aligned with factory hanger locations. Sounds better than factory but not too loud. Little to no drone. Does arrive with pieces for different vehicle applications that you will not need. Does come with hardware. You will need to supply your own replacement lead crush gasket if required between cats and start of Gibson system. ... show more

Great value for the product
Size: Single
Good growl, not too deep. Doesn't have that drone noise. I floored it once, and it was not loud at at all. Install was easy with the right tools. Instructions provided with the muffler were spot on good. Im just worried hoping that the metal will hold up against corrosion. Other than that, this definitely beats taking your truck down to your local exhaust shop. I installed this on my 2006 4runner Sport ... show more

Rattle sound
Size: Single
MPG increase drastically and so did low end power. Would have 5 stars however some of the hangers are a bit too long so there is an annoying rattle against the axil you’ll have to fix.

Fit is horrible
Size: Single
This thing is garbage. Vibrates on the frame. Extra tail section with no directions on which one to use (though both seem to fit but are slightly different). This replaced a previous Gibson that fit just fine but finally rusted out after 5 years. This one is different. It’s going into a muffler shop tomorrow morning to see if they can salvage it. If they can’t help, it’s getting taped together with duck tape and shipped back. ... show more

Cannot recommend
Size: Single
Shorted a section of piping. Was replaced by the manufacturer but that took more than a week to get. A couple of hangers were incorrectly located making it somewhat difficult to install and now hits the frame and rattles. This is not complicated install it is a manufacturer design flaw.
