After hearing 100s of sound clips, i cancelled my pypes mid muffler system. I decided it wasnt the sound I was looking for. from all the brands I heard imo borla and mac have the best sound. with borla out of my price range I decided on mac but on their site it says the mufflers are "aluminized" what the hell is that??
 
I'm happy w/ my flows axle-back for now, maybe some day ill put on an off-road hpipe and piss everyone off who lives near me. :)

Oh yeah!!!!! I love going out to warm up my car at 4:45am when I work dayshift:rlaugh: The first minute or so when cold it idles about 1500 til it kicks down. I keep it under 20 mph while leaving the neighborhood though.
