What has the bigger yield?

 

*watching*

 

i dont think there is really a big significant difference between the two

 

Well.. if there isn't one that is better performance wise.. how about economically? obviously the cat?

 

yeah when you delete your cat (esp. both cats) your car will smell like crap

 

where would you get a high flow cat?

 

the intraweb :p

 

you can go to magnaflow's website, everyone been using the magnaflow hi-flow cat but i forgot what the part number was

 

in the mid-pipe there is 2 resenators right????

when you change the header you delete the cat.....

 

no there is only one resonator, there is another cat in the midpipe

 

My main concern was with just the actual cat in the midpipe.

hi flow or delete?

 

the actual cat is in the header, the cat on the midpipe is a secondary cat and just catches what the first one doesnt.

replacing that will not yield any "good" results, your better off getting a header.

also, deleting both cats is a VERY good way to get pulled over, the smell and the white smoke blowing out of your tailpipe are easy give aways your car is modded.

 

ok.. but my question isn't about what i should replace. I eventually want TB.. dezod spec . I don't want a cat delete so what are my options as far as hi flow secondary cats - in case the manifold has a cat delete in the kit

 

any aftermarket manifold will delete the cat.

the only aftermarket cats that i recommend are vibrant and magnaflow, in that order.

 

thanks 909

 

yea i have header back exhaust, no cats, and i tell u it smells like crap, thats why my friend doesnt want to roll behind me when we roll together,

yea no cats= auto sniff test fail.....

 

no cat has best power but metalic high flow cat is 1 hp less but good priced.$$$. get megan, it looks like thiers a cat but thier isn't. import tuner.com has these resulsts posted with dyno on a civic

 

Check this article out about going catless. Should shed some light on the issue.

Question... Will only having the secondary cat in the midpipe keep my exhaust from smelling like butt? :o I'm installing my DC header and megan s-pipe this weekend
