Anyone with non NPP and secondary cat delete. Got a question.
Anyone with non NPP running a secondary cat delete have a video or can they chime in on the exhaust note after the delete. All I can find are vidoes with npp.

I’m probably not the exact candidate you’re looking for, but I deleted my secondary cats on my non-NPP car when I did my AWE Touring catback (which is fantastic). If you’re *only* deleting the secondary cats and leaving the OEM suitcase, I don’t think it will make a big difference. Maybe a tick louder.
