I bought an 05 civic ex 1.7 sohc vtec about 6 months ago, and I would like to do some mods, but I'm not sure what to start with. First off, the car is a 4-door and an automatic. Is it even worth it to fix it up? Also, it has a 100k mile warranty, and I haven't even hit 50k miles yet, so I really don't want to do anything that will void the warrant. Any advice? I have been reading these forums for about a month now, and I know that you guys are pretty knowledgeable, so I figured it would be best to ask the people who would know. Thanks!

 

Intake, Headers, Exhaust, Cat-back to start off with. as for is it worth modding..I would say go for it, it might be a little slower because it is an auto. I do not think that these mods will void your warranty but I could becompletly wrong.
