So I have a 09' civic si sedan, and I was wondering what company to get my intake and muffler from? Another thing is that I live in california so I need it to be CARB approved.
I know AEM has a cold air intake but i was thinking of a injen intake.
For my muffler, i wanted something that has 3 inch pipe and maybe even came with a silencer just in case my parents got mad at me for the noise
Any suggestions will be nice.

 

Have you ever modified a car before? What are you trying achieve by doing these modifications?

Edit: you must be like 16 years old huh?

 

well actually this is my first car i'm going to work on but right now i just want to get a little bit of horsepower for not such a large amount of money

 

My main recommendation is to stick with well known brands and not to cheap out with anything from ebay. Intake recommendations would be a short ram from any reputable brand with veins to accommodate the MAF.

Better yet, learn about the car first before you change stuff out.

 

i was thinking Greddy for the exhaust and then i was planning on waiting for the intake because i want to make sure i get something CARB approved but i wanted to know what you have on your 08' civic

 

Other than hfp suspension I'm stock. I'm not budgeted to work on my car right now, nor do I have time for it.

What Greddy exhaust are you looking at? Greddy SE or SP2 get my vote. I know i-vtec would concur.

 

i'm not sure yet but thanks for the help...i'm still just wondering right now i'm more concerned with helping my brother with his B18 swap he wants to get from password jdm

 

there is vids for sound and lots of dicussions about this kind of mods. read alot!!. (i am reading to learn also)

 

You can go to youtube and check out many vids of exhaust. I love my Greddy Evo 2 catback DCRH. I also love my Takeda SRI.

Read up on what is CARB legal and look at what style exhaust you want. Why would you wnat a 3in exhaust? Have you ever heard of back pressure? To keep noise down get a SRI and get a 2.5in or 60mm catback. Greddy is a good company.

 

the aem short ram is carb legal.
but the injen sri makes more power and is not carb legal at the moment.
i think last time i check it was pending.

and just like k5 said. im gonna ***** out the greddy se!
i have it and i love it. also i live in cali so i know what its like.
but i sold my sri because im going turbo soon.

and heres something to read up on an exhaust. my review thread of the greddy se.

I'd recommend reading your **** off. There are multiple Greddy exhausts and tons of threads on intakes, headers, exhausts and reflash.

I spent about 3 months reading before I started to understand what parts are good for my car and why.

I'll help you out with what I am leaning towards, K&N SRI, BCRH, Magnaflow short cat, Apexi WS2 exhaust. That should allow me to pass emissions in Canada

 

the aem sri is carb that's what i have if for my car. that's the reason i got it cause it's carb. i really wanted to get the injen cold air but i show its not carb approved so i willing to wait till that happens... but for exhaust i don't really care for quite one so i chose the skunk2 70mm exhaust, and i loving it now.. nice and good sound... and the good thing also it comes whit a silencer so if i get pulled over i can just pop that in....
