Just wanted to put this up for inquiring minds.....

I spoke to a Borla rep. the other day and he told me we are 3 to 6 months away from launching a cat-back system for the F. It would be nice to see how it sounds/compares to other systems on the way. I have always been pretty impressed with Borla, so we'll see if it continues.

Good News, Did the rep mention a price and/or HP gains??? I wonder if Five Axis might have something out in the same timeframe.

I'm kind of wondering the same about Five axis....The Borla rep didn't come out and say anything in particular, BUT it will be right in line with what other High Performance cars are getting. Sooooo, I'm guessing 15 to 20bhp gain.....7-10 at the wheels?

No confirmed price....

Will the cat back remove the secondary catalytic converters like on the 250/350? Will the primary cats be left or replaced with high flow,. that would squeeze out a few more hp.... Well Lexus gave Five Axis the chance to come out with some bolt ons without forced induction. Now I am thinking I'm wondering about K&N I saw somwhere in the forum they were soliciting test vehicles to research a new intake. Another company I haven't heard from at all is LMS. Just have to wait and see.......

That....I don't know. It would be interesting to see what they do with that, becausein my experience high flow cats = high $$.

Patience I guess....
