The Northstar in the Bonny has amuch throaty growl and virtually none of The engine noise I heard in the clip you posted. It took me back at first, LOL, it'* sounds a lot bigger than it'* 279 cobic inches. And one of the most "opened up" sounding stock exhausts I've heard. Which is a good thing for who knows how long it will be before someone offers headers for this N* orpan. Been toying with the idea of gutting the cats...but I already have too much on my mod table now.

If my throttle body wasnt off, I would record a sound byte.

Our LS4 is 325 cubic inches. I wish I could hear yours too. I am thinking removing my resonator.

Somebody post your exhaust clip!!

Hello all, great forum. I own a 06 gp gxp and my father has a 04 bonne gxp. I know its all a matter of personal opinion and taste, but I have to say I like the bonne sound better, especially after 4k prm'*. Theyy are both great cars though.

They are both great cars , i almost went with a Black on Black GP GXP when I bought my Bonny GXP. But the incentive( $10,500) sold me on the Bonny.

Here is a sound clip I of my Bonny GXP I posted some time ago.

I've been going to record the sounds... Promise I will do it soon.

Actually, the GXP sounds a lot meaner than the Corvette C6... sigh

Yes it does, Pontiac did a great job for once with flow and sound on the GXP exhaust and I love it!

When I have time to breath and relax I'm going to put laptop in trunk and record a nitrous run.
