Easy install sounds great
Great fit, and sounds amazing at 7k rpm
Good quality welds. I like it how they port out the flange to match the gasket. The wastegate pipe doesn't have that reduced pipe welded near the flange like the one in the picture shown which is a +.
Very happy with this purchase ! High quality welds.Sound and performs how I wanted! Shipping was fast and really well packaged! Would definitely recommend this to friends.
