Guys do a forum search as this has been talked about numerous times in multiple threads. Some of us love Borla, some have the TRD, and there are probably a few on this forum that have done the ricer's special and straight piped it to be as annoying as possible.
I side with Borla, but mostly because they are built very well using very high quality T304 stainless that will outlast your car. For those of us in the salt-belt states, that is important.
