I don't think you can entirely eliminate the rasp. After all, it is a 6 cylinder, and it is, what it is.
Good point. Honestly, I don't even think the engine is raspy even with these mufflers except for that one spot in the powerband around 3k. I love the sound everywhere else. I was hoping there was a simple solution I could drop in to mellow out that one range, but that would be too easy. I can deal with it though. Doesn't ruin the amount of fun I have with the car.
