Invidia 08 Subaru STi Silencer (for N1 Exhaust System w/ 101mm Tip)

Subaru STi silencer seekers, this Invidia N1 101 mm silencer insert is your go-to solution when you want to tone down exhaust volume without giving up performance. It slips into your Invidia N1 system and brings you a quieter drive while preserving that growl when you step on it.

Installed on the Invidia N1 exhaust, this STi silencer insert is engineered to maintain optimal exhaust flow and backpressure so you don’t lose responsiveness — but it tames excessive drone on longer highway runs or in residential zones. The key is balance.

Use it when you want your ride to sound aggressive but civilized. Whether for daily driving, noise regulations, or just neighbor-friendliness, this Invidia 101 mm silencer gives flexibility — you can install or remove as needed depending on your mood or environment.

Features & Benefits

  • 101 mm diameter design – built to match the tip size of the Invidia N1 system 

  • Stainless steel construction – durable and resistant to corrosion 

  • Bolt-in / slide-in style insert – easy to install or remove without modifying the exhaust 

  • Noise reduction without choking flow – attenuates excessive drone while preserving performance characteristics 

  • Fitment with Invidia N1 systems (101 mm tips) – specifically intended for 08 STi N1 setups 


Quiet Option (Why Use It?)

If your Invidia N1 exhaust sounds fantastic but gets too loud on long trips or in noise-sensitive zones, this Subaru STi silencer acts like a volume knob — dial it down when you need discretion, pull it out when you want full roar. It's a no-fuss, bolt-in “comfort mode” for your exhaust.

REVIEWS

JMC

I dropped this silencer insert into my 2008 STi N1 exhaust in Portland, OR and it made a noticeable difference. Still sounds sporty, but way less cabin drone. Easy install.

Living in Phoenix, AZ, I needed something to quiet down my STi at night. This **Invidia 101 mm silencer** did just that. The roar is still there when I want it, but now it’s manageable.
