high flow cat/test pipe questions.
I have an axel back exhaust system, and i want more sound out of it. Will geting a high flo cat affect exhaust sound? What about test pipes, if you have one, do you remove it and put a cat on for Emission? what high flo cats that are cheap and have 02 sensors?
|
i think my cat is built into my mid pipe.... maby i catn do this. ill take a look at it in morning
|
highflow cats are a waste of money unless your converting your exhaust to an ex, dont to the test pipe route. Its noisey and its illegal. You might get 1hp more with the test pipe, so imo its not worth breaking the law and polluting the earth.
Next time use the search button, they question is verryyyyyy common |
Convert to EX exhaust by getting a header, high flow cat, and full catback. Your exhaust tone will improve significantly.
Hell, even just a full catback will help. The small exhaust pipes before the axle back are restricting airflow and sound. Just for the love of god, don't get a fart can. |
I want to convert to an EX. I already have an aftermarket axle back exhaust.
If i get a header thast for a 96 EX it will fit perfect on my hx? After i install the EX header, where does the cat go? Can a exhaust shop weld on an aftermarket cat? Will geting just an ex header and high flo cat, and leveing mid pipe stock still affect sound? my new dwon pipe should fit my mid pipe? I think my header has a built in cat, so what is that piping thast biger in the middle of my mid pipe? If i get an ex header, that cat is what connects it to down pipe? no welding needed? Where do my 2 02 sensor go? one in the header and other in the cat? |

My recommendation is that if you like your current axle-back, buy a header, and a universal magnaflow cat. Go to an exhaust shop, and have them make you a custom 2.25" midpipe/S-bend and have them also weld in the cat, and an O2 sensor bung (directly after the cat). Put the header on beforehand, and attach the midpipe to the header. You will throw a CEL (check engine light). This will be fine for you to drive to the exhaust shop. Don't forget to take your stock catalytic converter with you (off of the car), they'll need the flanges. Also bring your O2 sensor, extension wire harness, and the new universal cat. Also, make sure you talk to the exhaust shop beforehand. |
Ok. im going to buy the stuff. i may not have the money for exhaust shop, but ill have the stuff ready.
here is the magnaflow cat, is this the cheapest cat to get? he list about diffrent pipe size. http://cgi.ebay.com/ebaymotors/Honda...spagenameZWD1V here is the O2 sensor extension wire harness. http://cgi.ebay.com/ebaymotors/02-O2...spagenameZWDVW Im still looking for headers, some say the pipeing size, so that may change what cat size to get? |
yea that'll work
you'll also need an O2 bung for the exhaust shop to weld on, you want it welded on right after the cat. http://cgi.ebay.com/ebaymotors/O2-Se...ht_2185wt_1186 shop around for better deals on that just get a megan racing header... i believe they have a 2.5" outlet quick question... you're not in California, right? |
im in CT.
Ya im looking more at headers around this price. http://cgi.ebay.com/ebaymotors/88-00...spagenameZWDVW Im also looking at some interior mods. I dont know what to get..! axhaust or interior mods.. The interior stuff is oem stuff painted, Dash Vents, Door Handles, and the plastic thing under the door handle, and Cluster Bezel. all painted Electron Blue Pearl. Im bidding on it, and it may be close to $90, which sucks. i think its worth it. |

If you can't shell out the money for a Megan Racing header then IMO you shouldn't be buying a header at all. The no-name ebay headers have pretty much a 50/50 chance on fitment, and a 50/50 chance on having crappy welds.
96 Civic DX (an HCF member) has one, but he got lucky and his is alright. However, that doesn't mean you will get lucky. Also, painted dash parts are pretty ricey and you will probably not like them later on. However, since you're buying new pieces I think it's no big deal, because if you don't like it later on, you can just swap the stock ones back in. Just a warning though, you will probably come to dislike a painted interior. There are 2 O2 sensor holes because you can use the 2nd one for a wideband O2 sensor to use an A/F gauge. This would be good to have for an N/A build. It comes with a plug, and you just plug up the 2nd O2 sensor bung. |
