Short exhaust

[Dick]

Have any of you guys experienced any strange engine behavior with a shortened exhaust? I think my catalyst efficiency sensor may be sending inaccurate data to ECM.

Describe the behavior

 

[Dick]

Sometimes acting like fuel delivery is changing, driving along at steady speed it sometimes feels like I'm getting a gust of headwind when I'm not. Like she's derating to a degree going down the road.

What mod did you do on the exhaust?

 

[Dick]

Just cut the tip/downturn off and welded it back on after the first resonator.

You are using alot of Diesel verbiage, is this a 3.0 or a 3.6?
