Long Tube Headers Cat or no Cat

[KWK GT]

2015 GTPP. Time for headers and have a few questions before I pull the trigger. I am leaning towards ARH 1 7/8" Headers with Cats and the Direct Connect to Corsa. I already have the Corsa Sport Catback. How loud is this setup? How much different is it without cats? Eventually would like to put a supercharger on the car and feel this is a good prep step.

Also who has the best deal on this setup. Any help would be greatly appreciated.

I had this setup in the past. It has a little rasp in the tone but it's not extremely loud unless you're above 5k rpms mashing the pedal. It's mainly due to the x-pipe and no resonator. I run the Krona catback now and couldn't be happier. It's similar to the Thermal catback.

The Sport sounds great with long tubes. No cats get very raspy though. I have ARH direct connect to Corsa. Was originally running Xtremes. Tone got way too trumpety. Added some vibrants to calm that down. Ultimately cut off the Corsa mufflers and added AWE Touring rear to the double x. Favorite sound so far on this build. But with the Sport you should not have to worry about that trumpet tone either.
