ok i have been searching for my answers and can't find anything. i have a 2005 EX and i'm wanting to get an exhaust system but i don't know what all i need. i know i need the catback but do i need a test pipe too. also do i need a down pipe or mid pipe (whatever the hell those are). i'm wanting to get a new header so will i need whatever pipe that connects from the header to the test pipe? sorry if this is noobish but i am and just wanting this cleared up for me.

 

actually better yet is there a website where you can buy an entire exhaust set up from the header down. one that takes the cat out. thats what i am really looking for. i just don't want to order somthing and have to wait to put it on because it didn't come with somthing and i also don't want to order a test pipe if one of these set ups come with it. thanks in advance.

 

Just go to ebay and search for an 05 civic exhaust. I just ordered an apexi ws2 for a good price.

 

well when you buy an exhaust system it usually connects right up with your cat converter. and if you want to get headers, i guess they can bolt right into your cat (correct me if im wrong im just guessing here) or you can get a down pipe to replace your cat. thats what im running, headers, downpipe, and exhaust. but the headers make a world of difference, sound wise. i have a greddy ti-c and b4 my headers it was nice and semi loud and throaty but with my headers/downpipe its crazy loud. it just depends on what your going for.

 

i'm going for crazy rice loud. and i did a lot more research and found out that all i need is the cat back, headers and a test pipe (down pipe). because i want to get rid of the cat too. now i just have to find out if i want a 4-1 header or a 4-2-1.

 

W.T.F.

anyways, yes it goes from shorty header, down pipe/cat, then catback. However, if you choose to get rid of the cat and run a test pipe/downpipe, it will throw an annoying CEL light that stays on. I heard of tricks around this method to make it go away using o2 sensor bungs and whatnot.

 

Or u can go all out and make a custom exhaust under 100$
An Rsx-s Pipe

 

I heard hp headers have a fitting problem. you have to grind on the frame. but the are a 4-2-1 instead of a 4-1 header.

 

crazy rice loud... why dont you just tear off your stock exhaust pipe, and throw a folgers can on there and put some broken glass in there while your at it...

 

stock exhaust ftw!
or pay 60 bucks to just have a straight pipe replace the muffler.
sounds decent w/o muffler.

 

or if you have no helpful advise you can keep comments like that to your self.

i Do not know were you live. But if you take out your cat. Good luck passing emissions testing. Plus you will through a code. not to mention your car will sound like a weed whacker. I mean if that's what you want then fine. But by doing H/DP/E your just making your car sound like donkey dick IMO. I am not trying to bash your opinion. But around this site you will not be taken kindly for trying to do the cheep rice burner way to make a loud car. Plus cars that sound like that get pulled over. ALOT. But good luck!!! Dont forget your v tac. lol

 

this thread just made my eyes bleed...

 

Hey I have a Greddy Sp2 Exhaust i'm selling, Used condition sounds awesome, I just PMED you.

 

craigs list?

 

i just bought new headers and a catback. i should be able to hook the headers to the oem cat and the exhaust to the cat right? or do i need to order additional parts?
