I have a 99 civic ex coupe (D16Y8) and its running a code for the catalytic converter. Basically the converter is trash. I really don't feel like buying a new one, and am thinking about just getting rid of it and the muffler for a straight pipe from the headers. I'm still new to Honda, and don't really know what the effects of that would be on the performance and mileage of my engine. Any insight into this situation would be greatly appreciated

 

it'll sound like **** more than any performance gains you'll get

 

Well as we know u do get a louder sound without a cat but you also can get a little bit more Hp. Also no cat is illegal in all 50 states I believe but yea I'd just put another cat on even if its a eBay cat

 

Really ? 0_o What kind of exhaust system is there that's louder than stock but sounds good ?

 

theres lots.

Apexi WS2
Spoon N1
Flowmaster 50
Pacesetter


more or less anythign that isn't EBAY, OBX, MEGAN, or Buddy Club



oh and straight pipe....

you are going to lose all your low end torque.... what little bit you actually have.

 

owns teggy and yazz, in civics???
get out of here spy!!!! lol
edit @ sol

get a cat, you will not even realize the 2hp you "gained"

most hi-flow cats flow just as well as a test pipe, on your y8 you wont even notice, AND you wont sound awful

 

<----killing time befor promethus

 

Just getta high flow cat that way will still pass inspection and has a bung for the o2 sensor........will improve sound and you should notice a lil better performance all while staying legal........
