I'm about the do a DPF delete and was wondering if it would further help to remove the catalytic converter as well, versus leaving it on. I'm not sure how much back pressure it creates, etc. Any thoughts? Thx

 

There's 2 different mindsets when it comes to deleting the cat.

Since you are deleting, you could just get a turboback exhaust without the cat. There isn't much point in leaving it on if you aren't emmisions compliant anyway. It should run slightly lower EGTs if running hot tuning than if you left it on.

On the other hand, leaving it on will cut back some of the exhaust noise, mainly the "woosh" noise from the turbo. It doesn't create a lot of backpressure and shouldn't be a problem unless it clogs up. Unless you plan to run crazy tuning, it wouldn't hurt to leave it on. Not running a cat will also increase exhaust odor a little bit.

 

depends on the state you live in and if they currently or plan to do emmissions testing...look into that.

 

No emissions test in FL. Looks like it'd be easier to take it off with the DPF because they are connected. Thx 4 the input!

 

I went straight pipe from the turbo back. Not going back!
