Well just got done. The bigger resonator FITS!!! And the car is ...... QUIET at idle and cruising ranges of the RPM. It does "WAKE" up when you drive aggressively or nail it. Best of all it has not lost its unique tone and sound characteristics at all under WOT and high RPM's. This larger resonator should satisfy the stealth needs of the older people in here

j/k lol.
There is proper clearance for the driveshaft, and it does hang just a tad lower (about 0.5") from the standard resonator, at least it is not the lowest point in the car.
civicdrivr: Give me a call tomorrow and we can setup a time if you want to switch to the larger resonator.
To all I will let civicdrivr be the judge of the difference in sound and for those that want to get it switched out please PM me for details AFTER civicdrivr gives his feedback.
