I just got a 2008 escalade and I would love to get a good rumble without spending $1000+. Tasteful sound not too aggressive. I see some cheap mbrp and Gibson catbacks. I'm very close to pulling the trigger on one of those. Anybody ever heard these in person or purchased one? I'm pairing this with a volant cold air I installed and Diablo programmer. I also threw around the idea of just putting a flowmaster on. Thanks for the input.
