I have an airmass catback system on my 96 civic ex and although it sounds good, don't get me wrong, the sound tends to get annoying during a long commute. the exhaust's tip measures 5 inches in diameter... i've been looking around for a while now and it seems as if 5" silencers don't exist. If anyone has any advice please feel free to drop your two cents.

 

greddy spectrum elite, looks sick, can't really hear it when cruising at a constant speed but it sounds really nice when your gasing it hard or reving up. might be some youtube videos to get a feel of the sound.

 

how does the spectrum sound say under a good load? like going up a long hill at around 3k? does it drone too much do ya think? it's a great looking exhaust in my opinion
