Cat-back quality

[importjdmcivic]

Ok i finally got pulled over for my loud exhaust a few days ago and have decided that a quieter exhaust would be nice. My question is...stated in the topic title...which cat-back has a better quality, the Greddy SP2 or the Apex'i World Sport?

heard better things about the Apexi WS than the Greddy...
