Just FYI.. The Borla exhasut for the IS-F is out. I just saw it on their website for $899.99. It's not a true dual exhaust but the muffler's have quad outlets.:(

I also ordered the Borla axle-back system, I had it done a bit differently. Pipes will not be polished (am not a fan of bling) and mufflers and tips will be powder coated dark grey.
Both Borla systems utilize the stock F tips. I'm confused by your statement by your above statement concerning the tips:confused:

Spoke with Chris at Borla and he convinced me the axle back should be what I'm looking for. Ordered from Speedfreaks and expected ship date is 5/18. Will keep everyone updated with progress and results.
What arguments did Chris use to persuade you to go with the axle back system? It has always been my belief that a V type engine should be equipped with a well designed dual exhaust with an H or an X pipe. It is my opinion that this is critical on a V8, V10 or a V12. I don't understand why Lexus designed their "semi-dual" two into one into two exhaust system. The axle back maintains this configuration, but frees up some of the back pressure with lower restriction mufflers and a better flowing rear Y.
