Was wondering if it was possable to upgrade to a more aggressive exhaust system without loosing the NPP Bi-mode exhaust option ?

Yes, you can get the Billy Boat Fusion bi-mode exhaust. If you do, I'd be willing to buy your OEM bi-mode exhaust and I'm in Chandler, AZ.

Thanks

And Billy Boat us right up the freeway by Deer Valley airport. Just got mine and will be putting them on tomorrow. They are VERY well built, can't wait to hear what they sound like.

You can modify your current exhaust. Remove the cans, cut them open and seal the perforated pipe inside. Sounds awesome, much louder open and still civil closed. Lots of threads on here discussing it and photos. I have the Z06 version on my car modified and couldn't be happier.

For the price of the B&B you could buy a set of headers. You would gain a nice level in sound and best of all see an increase in HP.

LT Headers, hi-flow cats & 3" X-pipe 3" back to NPPs, w/ NPPs open I assure you it will satisfy you quest for agressive. If thats not enough remove the cats although I strongly recommend against it for more reasons than I have time to list.
