I have a 2010 Denali. I have a brand new under warranty replaced Borla exhaust (their customer service is top notch). In deciding to keep the truck a few more years I purchased Kooks 1”3/4 headers and catted Y pipe. Zero regrets. Loud only on gas and zero drone. Only downfall it is expensive. Sorry can’t confirm sizes only guessing that the Borla is a 3”?

I believe for someone to help you, more information would be needed to help you diagnose the issue

I have a 2010 and my truck would do it while it was still under warranty, in both stock and tuned. Doesn’t throw a code, but mine slips under regular throttle and the RPMs will just jump. I change fluid every 40000kms and never any issue with findings. Also does it so intermittently that there is no rhyme or reason why.

Really late reply but it is a 75w90 gear oil and i recommend the Amsoil...but I am biased:) Sent from my iPhone using Tapatalk

i have the borla dual exhaust and i have always gotten compliments. a little bit of buyers remorse as i do like the sound of the corsa systems. my friend has an escalade and he put in a flow master and a borla tip. that sounds pretty nice too. there is a lot of excess weight and it is cleaner with aftermarkets. just to note my exhaust is quiet to me when i am driving, yet my wife gives me shit as she says she can hear me a mile away!

I am not impressed with the "look" of my frame. i have an annual rust check service done and have a full warranty with them. the wax was peeling starting in 2012. i used to spray rust check black paint to help keep it protected. i had installed in the fall of 2013 a gm wheel well protector. we have bad witness here, but my truck gets rinsed off daily. that is right daily. i also gets hand washed several times a week. still when i am under neath, i have concerns with keeping this truck long term. but it is what it is. in fact i figure i wash it so much, that i have caused my dash board to crack!!!!!

don't have anything to compare it too, but i went with blackbear based on these forums. truck is night and day better and the costumer service is great.

sorry just to noticed you were in the states...u have gots lots of options!!! lol!

OP, everything is fine, you have nothing to worry about.

i have a borla system on mine and love it. mine being a 2010 i only had the one option and if i am not mistaken the 11's or newer had two exhausts for sale. i get lots of compliments on it, and it does imo sound nice. i tried to post a sound clip a few moths ago from my iPad, but it wouldn't upload for me! i bought mine from a canadian website t dot performance and they were excellent to deal with.

send me a pm to remind me. i was just at the dealership putting summers back on, and i could have asked as i forgot. i have the bill at work in my files, so maybe from there i can help!

just had mine replaced under extended warranty last week.....there were two relays i believe. i can find out exactly when i pick up my truck again (sigh) today.

u guys will have to get it tuned out. the "it" is torque management. also, while it is a 6.2l motor, it is not a "corvette" motor, just to be p.c.
