Hey I'm currently running 98 integra ls with just a aem sri.. I'm looking to increase performance so im thinking about starting by getting exhaust and soon a new hi flow cat and headers. For the exhaust I want something with better airflow than stock but not too noisy since im in NYC. ive been thinking about the apexi ws2 or rsr but im not sure which is better... i rather have a straigh thru design rather than chambered cuz i like the look better but i heard they r really loud? well ne ideas? n also does ne1 have suggestions on the hi flow cat and headers? thanks
