Borla is great if you want it quiet but with a nice sound. I got one and I like it, it might even be quieter than the stock one...but the note is so much nicer! The car I guess purrs you could say, it sounds nice. Also from what I have seen they offer some of the best performance and economic gains. They do tend to be a tad expensive, but that all depends on where you look I found mine for $99 shipped. I thought that was a really good price considering an OE one from Advance was over $100.
