I have the 2004 SEEG and have both the perf and quiet baffle and race tuner tunes for both. Maybe its a fluke but ever since I put on the D & D 2 into 1, my oil sending units are getting cooked from the heat. I have wrapped the unit and that part of the pipe with some header wrap and this has helped somewhat. The unit gets hot and begins to send false or low readings. I go thru one sending unit per year. The clearance between the front pipe and the sending unit is only about 1/4 of an inch whereas the stock header pipe has about an inch of clearance.
So, 2 questions, for those of you that have this pipe, is your clearance that small and do you have similar issues? I have contacted D & D and they have not heard of this. My tune is great, flat a/f ratio around 13.5, 99.9 hp and 100 torque so I think that rules out too lean condition creating heat. Thanks!
