Where in SoCal are you located? I've been looking for this CBE for a while to replace my Fujitsubo but was never sure about the sound and what not. I am in the OC area by the 405 and 5.I too have this exhaust and love it. A little louder than stock but the tone is definitely more impressive than any other exhaust that I've heard. I'm still waiting for my ELH to come back from swaintech so I can finally put everything else on and get my tune.
On a side note anyone else with a 2015 sti have this exhaust yet? please chime in on fitment. My passanger side muffler is kind of slanted inwards and I wanted to see if it's just me or it's the acutal exhaust. I've tried adjusting it but to no avail. My next attempt is changing out the stock hangers. I've contacted the vendor I purchased it from and Milltek says there is nothing wrong and that I need to adjust again.
If anyone in SO CAL wants to hear the exhaust in person just PM me and We can meet and go for a ride. Again this exhaust is well worth the price and keeps the car quiet, but still manages to put a smile on my face.
