When I reseted my ECU I noticed a big difference in accleration. But now after a few weeks afterwards its hard to notice now. But that's probably cause its 100+ degrees out here and I have the A/C cranked up.
It's worth getting in my opinion, but search these forums if you do decide to get them. I explained how to install them on one thread cause its a ***** to do without the right tools or knowledge.
This is my first post here, i just joined. I have a 2008 Honda Civic SI sedan. Its all stock and i want a cat back. Im looking for moderate sound, nothing real loud. Can you guys give me some ideas of what exhaust to get? I need to know everthing that i will need to get this done...
