Uncle Rob Turbo Yukon: We Decided To Use The STOCK Exhaust... Can You Still Hear Turbo Sounds?

Watch on YouTube

What happens here

The final step involves firing up the GMC Yukon XL again to hear how the exhaust sounds with the cutout installed in the quiet (closed) position. The new O2 sensors and the E-fan conversion (which was handled by HP Tuners software) mean the engine should now trim fuel correctly and run more efficiently. The presenter expresses excitement about the vehicle's progress, emphasizing that it's now ready for a road trip and subsequent tuning by Super Tuner Tanner.

Goal: Confirm proper engine operation and system functionality, preparing the vehicle for further tuning and use.
