Hi, I'm still having trouble deciding on which muffler to get. I can't decide between the Dynomax turbo, flowmaster 40 series, and I've also heard of people using cherry bomb glasspacks. Which one of the three helps with power the most, which is the least fartcan-sounding, and which would be the best with both factors included. Sorry if I'm confusing you, I'm confusing myself! And I know this is a stupid question, but I'll be brave and ask it anyways; Do they bolt right up, or will there have to be modifications made? I'm still learning, and would really, really appretiate your help! And one more question, I've read about people removing their catylic converters and replacing them with a regular pipe. Would this be a good idea, or should I go with a high-flow cat? (and no, I don't have to worry about testing) THANKS A TON!!
