Install Headers and Secondaries, drone problem solved!
Borla sounds OK. I've compared it to a cheap Beluga (ebay $200 50mm exhaust) and I'd rather have the Beluga. Borla looks kinda cool out the back but it's not aggressive sounding. enough.
For those confussled... You know what it's it's like when you can hear yourself talk, breath, grind your teeth, deep inside your inner ear so much that it annoys the **************** out of you? Imagine the exhaust note echoing through your cabin like that around 3500 to 4500 Rpm.
Incomplete exhaust systems (muffler only) causes the exhaust note to be surpressed in certain ways but overly annoying in others. While when you have a full flowing exhaust, the exhaust note is less inside the cabin and more out the back where it should be. Basically the same concept as bass reflex in car audio systems.
