"I had to replace the entire exhaust system on my Toyota tundra. after about ten yrs old it needed it. I could not buy the resonator from you but the two converters and muffler were the direct fit kind. although I was a little surprised at all the welding that was done everything was in the right place. it took a little tweeking to align everything up all the parts fell into the right place. it was a one man job. worse part was getting the pieces out of the hangers. you amazed me with your prices and quick delivery. I will recommend you to everyone that needs parts.. thanks" posted by: badback on November 10, 2014
