I removed my resonator the other day and it sounds great. The initial rasp goes away within a couple minutes. The increased drone is not a problem. However, I am experiencing a subtle "raspy noise" around 3,000 rpms. I only hear the sound when I accelerate in 1st and 2nd gear. I'm wondering if this noise just comes with the territory or if it could be related to the piping,welding..etc. When I listen for it sometimes I think I'm trippin' out and it's just the sound of the engine. Does anybody know what I'm talking about or experience a simular noise? I'm assuming a high flow resonator would eliminate the noise but I'm trying to avoid spending $$ on that right now. Someone set me straight.
