Well I just got a civic and am planning on doing some upgrades to it and dont like to cheap out. I am looking at grabbing a AEM V2 cai and I have been looking at either the Megan Racing cat-back drift spec exhaust or the Greddy EVO2. From what I have read it seems like the Greddy is more popular but both should sound quite good.

Question 1 - With these two upgrade what will my car sound like? Is it going to be a little bit deeper or is it going to be one of those high pitched weed whackers I always hear racing around.

Question 2 - With those two upgrade will I still pass emission? Also if I decide to upgrade my headers how will that effect my emissions test? Sorry if those were dumb questions. I just thought I read something about that.

 

all those are great products. they will give u a nice deep tone at normal rpm's and when at high rpm's it'll scream and sound pretty nice. u'll pass emissions so long as u have the cat and all the sensors working properly.

is the cat and sensors all there already or do I need to buy anything else extra? Do I just need to make sure I dont screw anything up while installing it?
