K&N has now listed there filter on there website, likely wouldn't give much power but might enhance some sound. I am likely going to start with a downpipe then I might decide on a flash tune over the winter. The only mod I have done so far is spacers 10mm front and 13mm on the rear from burger tuning.
I'll check out rktune. Thanks for the info. I just put 8mm front and 12.5mm back from ECS. Looks 10x better. Thinking about springing for the H&R sport springs as well.
