I just deleted the OEM muffler & left the resonator - replaced muffler with 3” delete pipe. Just a bit louder the OEM - others say it sounds like a deleted diesel - decent amount of Turbo whistle. Nothing annoying @ highway speeds.

0 to 60 in 3 to 5 days. Just get the Ford V-8!

You can upwards to 400hp with a simple tune and Intake plus get 25 mpg on the highway on the ZL1, ZR2 models

The sound quality of both recordings is absolute garbage. Sounds like one recording was from the rear and the other one from the glove box.

Ok, I'll bite, how MUCH added performance? HP/TQ?

Dyno testing revealed maximum increases of 14 hp and 15 lb-ft at the rear wheels.
