One quick update...HPF just said they are done with their exhaust...they are just doing the finishing touches...so sometime in the next couple weeks I imagine it should be done.
Also with regards to the midpipes it just gives you a little bit louder, and little bit deeper exhaust note. I installed the berk midpipes thinking it would make a huge difference. If any of you are in my area, and would like to see the difference feel free to let me know.
I will probably be going with HPF exhaust next month when it is out.
