I posted this on the performance/modification forum, but i thought I would let everyone know about it.
Spent some time yesterday with Dave Borla at Borla Performance Industries. We put my IS-F on a lift and talked about the design of the exhast. He is definitely going to be making it a FUNCTIONAL quad exhast. Those tips will no longer be for show. He understands that the stacked exhast is a trademark of the car, and the design will incorporate that.
we also talked about making 2 production versions of the exhaust. One will completly be a new exhaust system, removing the emissions control. The other will leave the emission control on and will just be replacing the muffler and pipes.
This is all just discussion right now. I've left my car with him for a couple of weeks so they can work on it. I'll keep everyone updated as i know more.
Good news. Can't wait for an update.....
