I've tried stock pre-2011's with the stock, corsa, and b&b fusion exhausts (those were the only mods on the cars). The most burbling and popping came from the b&b fusions. But, it's still not nearly as good as the 2011 system. And the good thing about getting a 2011 is that if a LEO does decide to pull me over, he won't ticket me for an aftermarket exhaust...what do I do??? From what the engineers said, I can't just put in the 2011 exhaust system into the '08 because there is also the engine tuning aspect that leave the exhaust valves open for a bit on the 2011, that enhances the burbling and popping sounds.

My '09Z has an H pipe. Do the '11s have X pipes?

Your 09 stock Z isn't supposed to do it. 2006-2010 stock exhaust does not pop/burble on decel.

I like the popping, but then again - I don't own a honda or a purse.

:nonod: Sorry sir, no they haven't....not at least on any of my cars.....they popped when either the header flange gasket was cracked or collector gasket cracked, otherwise ZERO popping!

And to you exhaust-popping lovers....HEY GUYS...lighten-up a bit! or maybe go pop a bit :rofl::rofl::rofl: I didn't start this thread to debate the merits of popping.....I was seeking the collective expertise of this forum for a technical answer, not to criticize those that like popping. Thanks to those that contributed their positive input!

And for those of you still interested in GM's official position on this I have it! I called my newly found GM "insider" (Group Manager, Brand Quality Performance Cars / Corvette) and here's what he told me:
Seems pretty straight forward to me and several others have posted their thoughts as well along a siliar line of thought.

Now for the rest of you....I'm very curious to know if anyone that has headers on their car with no cats.....does your car still pop?

Sheesh, everyone has given this guy their opinions and a thesis on why the popping occurs....but no one has given the poor guy a straight honest answer.

The answer is easy.....you want to stop the popping? Change to a 2006-2010 Z06 exhaust and you're done. No more popping.

For others interested in the popping that own a 2006-2010. All you have to do is the muffler mod and TADA...you now have popping. Pulling the fuse for the valves does not create popping....the only thing that will create the popping is when the baffles are welded shut in the stock mufflers.

Hope that clears it up for folks that WANT, and DON'T want the popping! :thumbs:

So it's normal to hear a distinct "pop" after a quick shift from 1-2? I understand the "burbling" is normal but op mentioned he had a noticeable pop during spirited shifts.
