mods for 2009 1.8L civic 4 door
 

what exhaust muffler inlet size would fit my civic and is it possible to do bolt on? also what exhaust muffler do you recommend. I was looking into a cherry bomb or a magnaflow/flowmaster. im looking for a pretty loud sound but quiet while cruising.

Check out YouTube videos to hear what sounds good to you.

You might be able to find a bolt on but any muffler shop will have one that fits

If you want loud, you can run no mufflers at all. Probably not recommended, but it’s the cheapest option. Keep the resonators and cat otherwise it’ll drone like hell.
