Good Product

Easy to install on 2.7L Tacoma. Took about 1.5 hrs. Sound is good. Not overly loud, but deep tones come through. Be sure to fully tighten u-clamps for leak free connection. Kit does not come with new CAT gasket, so you'll need to pick one up. They are about $3. Overall good product, shipping, and installation. Sounds good too.

Thought I got a real good deal,system arrived in a very timely manner. This was my third gibson cat- back system. The first 2 fit like a glove, this 1 did anything but, hangers did not line up right on tail section, loop over axle nowhere near centered. It took alittle rigging and bending of hangers to get it to hang right, and shortened up tail pipe so loop would not hit axle. Not pleased at all, part# was correct but engineering way off, I doubt this will be printed. JD Charlotte NC

Nice rumble but not to loud,& add acceleration. Haven't done mileage check yet but by the added performace mileage should be better. Easy installation if you read instruction first and follow them.
