Looks very strong, well built. When I gave it to the welder in the muffler workshop, he was very impressed, he said he had never seen such a beautiful resonator. Noise coming from my free used muffler. It did a great job muffling any sharp edges of the exhaust pipe, but there was no escaping the terrible rumble of the mufflers. Part A++, but that won't fix the irreparable. I recommend.
