The kit looks pretty sweet but it does not appear to have a catalytic converter, you might check and see if it will be smog legal in your area, or budget to add one if you need.
I live about a jillion miles from the nearest smog check station
, I used a catalytic converter anyway to keep it cleaner smelling when the top is off and to cut down on noise. I want the extra muffling of a cat as well.
That being said mine goes like this:
Thorley header w/ 2" reducer > Magnaflow universal cat #91004 > 2" pipe > Magnaflow muffler # 11114 right before diff > 2" pipe out the rear w/ turned down.
I modeled this system, down to the stainless steel muffler and cat part numbers, after the personal rig of a Samurai guru from Trail Tough. While I only have 10 miles on it (Back off the road for trans rebuild) it has a nice note but pretty quiet, cant smell anything and seems to flow PLENTY! Because I went on ebay for the muffler and cat I got each for around $50 brand new shipped.
I have no long term review but I consider it a HUGE upgrade from the 2.25" and Flowmaster. Performance is better in every respect and it no longer offends my sense of tranquility.
