Very good quality, and it does help with the intake manifold restriction. I did it the same time as 100 hp injectors so I cant really say exactly how much it helps but i did not have problems with egts with stock turbo and 4" exhaust. The stock elbow bolts with have to be cut down or have about 1/2 in of washers added otherwise they will bottom out (should be a warning with product about this).
