I am running a DC Sports Cat-back system on a '94 honda civic hatch, and i was wandering which brand of high-flow catalytic converter/test pipe would be best for my application? I am going turbo eventually, but not anytime in the near future.


The choices that I am thinking about are:

-Megan high flow catalytic converter
-OBX high flow catalytic converter
-Skunk 2 test pipe


*Note* if there is any other brand that is not listed that you would suggest over these, please let me know.

Thank you

 

OEM.

if your factory cat is clean it dosent hinder airflow that much. dont waste your money.

 

Random technologies are dyno proven to be effective...a little pricey however. Even a Magnaflow high flow cat would be good...stay away from test pipe though...loud and illegal...not worth it imo.
In the new Import Tuner there's an article where they test the stock cat against high flow cats and a test pipe on a 99 si to see the power differences, I think the test pipe has like 1hp more then a good high flow, and stock obviously made the least amount of power.

x2. Dont pollute more than you have to. I mean air pollution as well as noise pollution.

thats what i think as well. I dont see the point in going that much (if any) faster and polluting more....not worth it IMO. Stay OEM
