Header... Cat back... High flow cat??

[ShagginJet]

Considering dropping about $100-$150 on one of the above. Just wondering what people have found as an average HP gain when adding the above mentioned to a civic. Want to get the best HP for the cash. I want that exhaust sound and that's why I want to use the $150 towards that instead of other HP adder type mods.

Save your money and get a catback when you can afford it. Then header/cat IMHO.

^agreed.
By just putting in a header its like taking a mcdonalds shake straw and taping a coffee stir to the end...its gonna be restriced pdq.
As for the cat, its not going to flow a whole lot better than the stock one when the stock exhaust is still on...2 coffee stirs and a mcdonalds straw in the middle...it just doesnt help...
Scenarios: (- is stock piping and = is new high flow part)
Header: =------
Cat: -----=-----

so what about cat back??? are you guys saying that when i FIRST got my catback it made NO differance at all because it still had teh stock cat and manifold.. i know a few fairly high HP cars running stock cats.... which would negate your argument.. i agree save for a cat back and go from there.. then header.. i wouldn't consider the cat unless you are pushing serious power.. its JUST a civic... i mean im not saying it makes NO differance it DOES.. but its not liek some big turbo car or anything..

[pdiggitydogg]

no there would be gains made when its still the stock manifold but new exahust piping because its more flow after than before. that air doesnt have to travel as far in as a compact area. since gasses like to expand the sooner they can the better; but if they have to be compressed again after they are more free flowing...i cant think of a good thing to say now but you get the idea...its not as good. as for the cats...it is just a civic so you dont need to worry about it anyways...unless youre running FI where the "recommended" 3" piping wouldnt fit the stock cat (I dont know any FI civics that run 3" pipe though)

for 150 dollars I wouldn't even consider buying a header, cause you get a real crappy quality one. save upo for a dcsports or equiv.

I was reading an article where these guys put a landspeed racing hiflow cat on a 1991 civc hb. I think they said it generated a whole 2 horsepower, not including what other mods it had done to it.

I'd say either save your money and buy a full exhuast later, or just peicemeal it together. Buy a hiflow cat now, do some piping later, then the back end and the header all separately. itll just SEEM cheaper...

you are right... and wrong.. lol used DC headers go for like 125-175... so hes RIGHT in that range... i mean sure it would take some hunting and digging.. but one could be sourced for that much..

ya i meant RIGHT NOW he just sold the last one he had for my car D16Z6.

he's got tons of them and i think he's getting more

[oc civic]

i think that SO many people are swapping now that D-series stuff is getting REALLY cheap ESPECIALY used.. i would just go used on something like a header... its pipe.. and for the most part in the engine compartment (unlike exhaust that has the chance to get ****ed up) as long as there are no dents or anything i think used would be the rout to take..

"IF ATTITUDE HAD A SOUND, THIS WOULD BE IT. A STOCK replacement muffler can be pricey from the DEALER. And it would be a shame to go to Midas or Mieneki. Why settle for less? MSRP on this item is $199. Item is a BRAND NEW ITALIAN ANSA SPORTS MUFFLER specifically made for HONDA CIVIC CRX (2 door) 1.6 16V Si, Esi, V-TEC (1988-1991).

you have got to be kidding me. Okay guys, show me your honda motor expertise and tell me what is wrong with this description, the winner gets something...I don't know what but they will get it. I'll give you a hint...this car is not an nsx.

edit: besides this is an axle back and you were talking cat-back. Go with a cat back. Intake, then exhaust, then header, don't worry about the high flow cat yet.

Well the first thing I noticed is that the 88 - 91 didn't come with a Vtec motor

very good.

this guy is a tool, don't buy anything from him.

[ShagginJet]

He got the text directly from the ANSA site. He's being a lazty *****. What I know is that the SI is the same as my car more or less, so it won't matter. I meant general look and maybe if anyone had heard one of these.
