My Civic Si Resonator & Muffler with 2 1/4in Custom Stainless Steel Piping
This modification really make a lot of different in power delivery !
No hesitation anymore from lower rpm to higher rpm.
Torque is immediate from stop,
Acceleration at freeway speed from 70mph above really much faster now...
I guess the combination of larger Noblesse pipe
and 200cpsi High Flow HJS Cat really free up the flow,
no more bottle neck yet still keep the torque available, actually I feel more torque now down low...
What amazing is the sound loudness stay almost the same but it's deeper and fuller now !
Basically this configuration is the same in concept/configuration as HKS Metal Catalyzer for CR-Z
I wonder how better this will become if I re-tune my car
Very nice and thanks for sharing those pics. What do you think a tune will help resolve it boost for better performance? Air/fuel ratios, ignition advance, etc.

Yes, the A/F ratios and ignition can be further optimize,
I think I need to go K-Tuner now...
My AEM F/IC-6 is not that precise...
After several years and many miles with "RICH" A/F ratio to cope with the Supercharger, the S2000 AP2 exhaust tips start becoming "black" in color... so I decide to replace it today with...
another Brand New S2000 AP2 OEM Honda exhaust tips again
