I used this exhaust as the only exhaust on a Nissan Frontier and bought it to try as we don't have 3" pipe bender tools at work. Putting everything in one sentence made the job incredibly easy. Fitting the 2 inch pipes leading to the muffler took almost 3 hours. Building the exhaust pipe with this kit took maybe 45 minutes. It really simplified my exhaust and the big bore pipes added a nice low rumble to my v6.
