Very fast shipping I'm very happy

Great service...

The exhaust clamps are terrible and it leaked out of every section clamped together. The exit of the tail pipe was extremely low so low that normal operations of the vehicle weren't possible without it hitting. I had to spend an extra $200 to have the exhaust welded and manipulated so the exit of the tail pipe was normal. The sound of the exhaust doesn't compare well to a flowmaster or magnaflow either. I am very dissatisfied and disappointed in my purchase of this product for my Nissan Titan

I was very apprehensive at first but really needed the parts from USA ant thought I would give it a try. The whole process went flawlessly. The corisponding information about what I had perchanced was brilliant, along with the info regarding where exactly in the world the package was. Even when it reached NZ they walked me through the procedures with customs which also included the fact that all duties had already been paid to NZ customs. Fantastic service and wouldn't hesitate in the future. Thank you very much.
