Anyone have some audio clips or can let me know what they went with in their 5.0 SC XF?

I am debating getting full ardent but don't know if the no cat headers will be good. Thoughts?

 

There are quite a few videos on Youtube of different exhaust setups. If you're going to remove your cats, or in your case with a full Ardent system, You're definitely going to want to have your car tuned for those mods.

There's been some discussion about switching to "Euro 6" or something in the computer to deal with the second O2 sensor, which even with the simulators (those extensions to mostly remove them from exhaust flow) still has some impact on A/F ratio.

I've given strong consideration to hollowing out my cats to increase the flow as well as remove heat from the engine bay.

 

I have the ardent headers, a custom x pipe, and the ardent valved exhaust. As far sound is concerned, there wasn’t that much difference between just removing the cats and adding the headers. Prior to the ardent stuff I just had a car delete and spires exhaust.
