New M&K Prototype masterpiece for 3.2

I was talking to Ben at M&K a few weeks ago about possible exhaust systems for my 3.2L Carrera restoration project. I had just rebuilt my 3.2L engine with 77K because it was burning a quart of oil every 350-400 miles(bad valve guided). I put in new rings(alusil cylinders), 964 cams, extrude-honed intakes, MK 1in /1 out muffler and a SW chip. The car runs and sounds great. However, I felt my stock heat exchanges and stock cat were too restrictive. Ben started thinking and came up with a great idea, remember, I live in the Peoples Republic of CA, so California emissions is the 800 lb gorilla. We decided to go with SSI's because I need heat and liked the quality of the headers. We decided to install two 300 cell cats in parallel and plug into a MK 2 in / 1 out muffler. I am using the single outlet muffler because I do not want something too loud. Hear are some preliminary photos. I would like to state that I talked to many shops about custom fabricating a high performance header/cat system but Ben was the only one who would not only agree to do the job but also call me back and do the groud work to source the cats and other materials. Ben is by far one of the best Porsche specialist to do business with. His customer service and help is a 11/10. Please comment.

Note: These are preliminary photos during the fabrication process. The final welds have not been set. I do not have a total cost of the system yet, however, it is much cheaper than the GHL system.
