Before I start, because this is my first post, I just want to say that this is a great site?
I want to upgrade my catalytic converter and muffler. Through all the reading from the site I have decided to go with Magnaflow’* cat. #91006 and muffler #12266. Now the questions I have, because I am getting a little confused are: 1. from what I have read, I will gain on top end speed (?), but lose low end torque. Is that so? 2. I like a nice throaty sound but; will this drown out my sound system? I listened to some of your clips (nice) and read you go back and forth about the sound and which is better etc. I live in NYC, but I take many long trips. Will I want to shoot this car after two hours, i.e. how does it sound on the highway? Oh, I should mention that I made intake mods. already.
