I don't have catless primaries but HFC primary, deleted secondaries/quad resonated x-pipe with the OEM exhaust mod. I can post a vid of that if you like. I also have a sound clip from when i dyno'd the car. I had to add another set of resonators to the x-pipe because I thought it sounded way to high pitched & raspy. I love the exhaust note now though.
