Heres a look at my custom jerry modded invidia 02. I prefer to use cast pieces on my car for reliabilty sakes. plus I believe they just work better in many cases. The invidia as it comes has a simple straight divider installed from factory. its straight, and short. pretty much a half *** effort at keeping the two paths separated. on the main flow side the flow would open to a larger than 3 opening and have to find its way back to a 3 inch opening into downpipe. buschur tested this piece and found it not to work as well as megan 02. I believe that to be true just looking at design. So I decided to take some time and improve on the design. I didnt take pictures before I started. It was used and dirty on inside so it wouldnt have photographed well. But basically I took some cardboard and kept trimming it till it looked like it would fit inside and make the flow paths what they should be. I then cut the piece from stainless u bend and welded it in. There was lots of welding and grinding. more welding and grinding. all in an effort to improve the flow path and re-entry point for wastegate flow. I think this will work well. The re-entry point is at the 02 sensor where turbulance already exists. I dont know why the meagan piece puts it right in flow path? There was also a big dip right before exit on the invidia. that dip was filled with weld and ground down. Then she was ceramic coated ready for action.
