Review on Pacesetter 753506 Direct Fit Catalytic Converter by Byron Lucas

This job is definitely not for the amateur, but if you have a good pro-level tool kit it can be done. If you can't do it yourself, you're more than welcome to take them to your mechanic to have them installed. The fit was perfect and this is a modified version of the misguided design that Nissan originally put on its Armada. As a former Nissan master with 25 years of experience I feel they have been worth it. I've had them for 3 months now and they work well and have passed government emissions with no issues. I don't know how long they will last, but for a third of the price Nissan is asking, it was worth the play. Very happy with it so far.
