Buried in that press release:

"Exhaust system and resonator specially tuned for the 6.0L LIVC engine’s Active Fuel Management operation. This new exhaust system ensures comfortable interior acoustics and a pleasant exhaust note during both V-4 and V-8 operation"

What it means: No more big resonator at the back, replaced by new mechanical exhaust valve, which is a 30+ lb net weight savings.

 

having driven both regular and hybrid escalades, I like the acoustics of my hybrid better. the resonator is doing a good job.

 

KC,
Can one switch to the new exhaust system, and remove the resonator on 2010 Tahoe? or is it a total different system?
Also can I upgrade to the latest onstar software mentioned above with my 2010 model?

Thanks

 

I'm sure it fits, and it lets you put the spare tire on if you want. But I'm sure the 2011-spec cat-back exhaust isn't cheap, it it's even available. Esp where you are.

The On-Star update should just be a software update. But there may some interface issue I don't know about that may prevent backwards compatibility to 2010MY. I noticed all the 2011 GM models have the new OnStar. I can ask about that. But usually the dealers won't update something unless there is a specific issue that is addressed by the new software. I know my 09 Saab doesn't have the latest-greatest stuff flashed in the ECM and TCM, but dealer won't update it just because.

 

Thanks KC for your reply.
I thought it would be a small valve that I can use instead of the resonator. I am sure my dealer doesn't have it but they can order it, but I don't think I will do that if it is not a cheap part for the time being.

I would appreciate it if you can ask about the Onstart upgrade, I can have my dealer upgrade my software without extra fee if it is compatible., I have done it before.


looking forward to hearing from you
Thanks
