I have a dc sport 4-2-1 ceramic header with a skunk 2 mega power catback.
I'm about to put them on and I was wondering would it be better to use the stock cat (as long as it isn't clogged up) or buy a hi flow cat.
Any suggestions? Thanks

 

I've got a Pacesetter header and Ansa exhaust(stock sound) with the stock cat. I've never heard of a high flow cat. I guess if it flows the exhaust better and you don't mind spending money, go ahead. I've heard somewhere that if your exhaust flows to much, you will actually lose power;however, i'm no exhaust expert so get other opinions.

 

thanks

 

get the high flow cat, hondas always get something out of more flow. i just took the cat off my car and it helped. i think it flows a little too much but the high flow should be perfect.

 

high flow cat= stock cat punched out. trust me you'd be better off just using ur current cat and punching out the insides... that way you wont have emissions problems when you go to inspect and u'll get the high flowness of an "aftermarket" cat from a stock one. been done before works great if not better than those fake cats. h:

 

Are there any benefits of doing this?

 

the only thing i can say is that you'll pretty much get the same result from doing this to your stock cat and buying a high flow one... so its up to you whether you'd like to save yourself some money or not... in some instances punching it out may cause too much flow and not enough back pressure resulting in minor hp loss but this is only in small instances on certain cars. if you want try it out with your stock cat punched out and if you dont like the difference purchase a high flow one then, that way you can test both ways out.

 

i'll just keep my stock cat, thanks guys
