Itâ€™s only Wednesday and Iâ€™m already Pissed Offâ€¦ Alright I have an 1995 automatic Integra LS it has about 133,000 miles on it and I recently lost to my friends 1996 Honda Civic DX hatchback 3 times which is completely stock and is automatic! I have AEM Cold Air Intake, DC Sports 4-2-1 Header, and a Mugen style twin loop muffler. His hatchback has about 70,000 miles on it, but still what happened? My dad said that my catalytic converter might be backed up and maybe the exhaust to. What type of cat should I get something for $100 bucks? And in the winter I plan to rebuild my engine because my throttle response is pretty gutless. What type of pistons should I get? I was thinking either Type-R Pistons or JE SRP Pistons and what type of compression should I run?
