I have a Gibson Super Truck cat back exhaust that I need to sell. Part number 6514 for the reg cab short beds, however, I'm sure it would fit extended cabs too with a little more work. It is one complete welded unit and will be a very easy install. Just cut off your old exhaust, mount the Gibson in your rubber hangers and use the supplied 3" band clamp to mate the two pipes. Some of these systems were shipped with round tips, but his system has the two square polished stainless steel exhaust tips. It is used but has no damage, defects or problems. This system is loud. It will make your hemi sound like a hemi. If you like to be heard, or like to hear yourself, this system would be perfect. I would prefer local pickup since this would require a very large box and be expensive to ship. These usually sell for around $265-$300 new. I figure $150.00 would be a good deal for somebody.
