I cant vouch for the sound and/or performance quality of ebay bought components...
But I can tell you that I know a few guys who had similar designed rear sections on their civics/crx, and I can tell you that if you like to have your car slammed, then you might as well not connect that damn thing to the hangers, becuase its going to scrape EVERYTHING.
That Round sideways muffler is just asking for a good shot from a manhole cover or something. My cousin had one of those things, and we used to laugh our asses off everytime we drove behind him.....Everytime the road would dip or rise, sparks would fly.....hahaha
If your going to get the muffler in the OE position, I highly recommend one that utilizes the oval design....Like the thermal r&d. I have had my thermal resonator scrape, but never the muffler.
Anyways its better than the dual peashooters...hehehe
