EVERY 9th Gen Civic Si Owner Should Do THESE 5 MODS

Today I’m breaking down the top 5 modifications that made the biggest difference on my 9th gen Honda Civic Si. I’ve done a ton of mods to this car over the years, but these are the ones that legitimately transformed the driving experience. Here’s what made the list: 🔵 #5 – CR-V CarPlay Head Unit Swap A simple OEM-plus upgrade using a 2013 Civic Si bezel + a CR-V 7-speaker head unit. Huge improvement in navigation, usability, and daily drivability. ⚫ #4 – SRP Racing Pedals Full CNC aluminum pedals with tons of grip and customization options. Way better feel than the slippery stock rubber nubs — especially in wet weather. 🔊 #3 – Full-Race 3” Exhaust Header-back, deep tone, great sound, and makes it easier to tell where you are in the rev range. Loud but not obnoxious (unless you want it to be). ⚪ #2 – Wheels & Tires Swapping the heavy OEM Si wheels (50 lbs per corner!) for lightweight RPF1s completely changed the car. Faster turn-in, lighter steering, and massively improved feel. 🔴 #1 – Acuity Adjustable Short Shifter + Likewise Shift Knob Hands-down the biggest improvement. Fully customizable throw, height, gate spacing, and angle. Paired with a create-your-own Likewise knob — this setup transformed the entire driving experience.
