Does anyone know the difference between the two GM part numbers 19433760 and 84460754? I have a 2022 Yukon Denali and looking to upgrade my exhaust system. Both show up when I enter my VIN.
Thanks. I too am faced with this decision.19433760 has a front resonator just before the muffler and is branded as Borla
84460754 is GMPP (made by Borla) and has the resonators at the rear near the tail pipes
If your putting on new vehicle that is under warranty I would ask them Dealer and make sure if they install warranty on vehicle will stay intact.
If not under warranty aftermarket might be a good alternative.
I have the Borla 140557 Touring on a 2019 Tahoe. Currently the Touring is the only available option from Borla for 2015 thru 2020. This has welded on chrome tips. No visible resonators. It does drone between 1700 and 2000 RPM. I have talked to Borla about the drone and they are waiting for me to send them a recording of said drone. They said it could be defective. They also told me that the system is designed with the resonator built into the muffler and that is how they achieve zero drone. I'm not sure if this is BS or not. I will send them the recording and see what they say.So I squeezed a tad bit more info out of Borla customer service. They told me GM 19433760 would be more similar to Borla's 140859 "S-Type" sound level (the louder one).
So to re-cap, the "Borla" options are:
GM system - has x1 resonator before muffler; Borla denies they make this
84460754 (has "GMC" etched in chrome tips) MSRP $2395.00
GM "by Borla" systems - has x2 resonators after muffler; probably has "Borla" etched in tips instead
19433760 (chrome tips) MSRP $2495.00
19433762 (black chrome tips) MSRP $2495.00
Borla Touring systems - doesn't appear to have any resonators per photos
140858 (chrome tips) MSRP $1931.99
140858BC (black chrome tips) MSRP $2036.99
140858CF (carbon fiber tips) MSRP $2999.99
Borla S-Type systems - same no resonators
140859 MSRP $1871.99
140859BC MSRP $1999.99
140859CF MSRP $2554.99
