Right Joe as well as an F- sport intake for the IS250/350 as well. How is that R&D going for the IS-F? Here is the link at the SEMA show.

The under body diffusers are for down force, but I think you are talking about the exhaust outlet. The do not create any down for but defuse the turbulence created by mass amount of air moved by the engine at high speed.

Different design. The Z06 uses vacuum system operated by the electronic switch. The muffler itself has dual path. One for low speed and a 2 1/2 inch outlet for higher speed.

IS-F has a traditional exhaust system. IMO, IS-F exhaust is simpler and better. At least to better to modify.

The Sport Line will only support the IS 250/350. They will not have anything for the IS-F at the time of launch. Hopefully they will come out with something in the near future, but I was told there was nothing on the drawing board yet.

I don't think anybody has due to Lexus or some people saying that those stacked exhaust serve a function to keep the car grounded when going above 125mph...if you put a regular exhaust...it would have problems at high speed...
