My vote is HKS Hi-Power 75mm Single with Berk 70mm Test pipe. I have had this setup on my car for almost two years now. Love it. Top up you can still hear music and have a convo. Top down its nice and deep. No rasp/rice at all. Even gurgles/pops a bit on rev matching. I have tested it in the tunnel down in Mobile, sounds almost exotic near 9k.

 

I had the same exact set up, and YES it sounds exotic above VTEC. It's almost addicting and I did get pulled over once for going WOT!
BUT I sold it coz I couldn't stand the single exhaust look.

 

Bump! Where can I buy the Q300 shipped to Guam? Anyone know if this exhaust can be shipped through USPS?
