i've got the 3"atr dp i'm going to put an a cut out and a highflow cat on it ! should it come from the dp to the cat then to the cut out to the rest of the exhaust or the dp to cut out then cat and rest of the exhaust ? i was thinking dp-cat-cut out-exhaust ! that way the cat will help with boost spikes . is this right ? :squint:

Re: exhaust questions
Hey Kevin,
I think you want it at the bottom of the downpipe, before the cat. With a decent working external wastegate system, you shouldn't see boost spikes, regardless of whether you have a full cat / muffler exhaust or a straight downpipe dump.

Re: exhaust questions
put it prior to the cat... Some of the exhaust will still filter through the cat, so it's not 100% open. The boost spikes you will likely encounter will be from a 30+ mph roll.
