It only makes sense that GrimmSpeed employees drive Subarus. Chris M gets to and from work in his 2022 VB WRX. In this video he will showoff some of his upgrades and talk about what he plans to do next to build more power.
Follow Chris! @slow_wrx37
Shoutout to @j.hanth for sharing this video.
He has our GrimmSpeed Unequal Length Exhaust Header bolted up and can't help but start the car to hear how it sounds. Although this doesn't feature our GS Catback, you can still clearly hear the difference the Unequal Length makes to the exhaust note.

Top Mount or Front Mount…
We build both intercoolers for a reason.
TMIC: short path, fast response, perfect for street-driven setups that still mean business.
FMIC: larger core, direct airflow, built to handle heat when the power goals climb.
Different layouts. Same goal. Unbeatable performance.
So what are you running?

Whether choosing our VA or VB Equal Length Headers, you can't beat the quality. Which one is right for you?
Equal Length design means consistent exhaust flow into the turbo which translates to better response and a more controlled powerband. Built right and SEMA certified.

First CARB EO. Big moment for GrimmSpeed.
The GrimmSpeed 2-Bolt Up-Pipe for EJ25 just secured its official CARB Executive Order #D-895, marking a huge step forward in emissions compliance without compromising performance.
This isn’t just another approval… it’s GrimmSpeed’s first CARB certification, and it sets the tone for what’s coming next. This is just the start!
VOLUME UP!
We recently released the new and improved GrimmSpeed Gentleman’s Catback Exhaust and people have been asking for sound clips.Clean Rumble. Controlled. No harshness. No Drone. Available in resonated and un-resonated versions. This video shows our un-resonated version.
Hear it for yourself.

Higher flow. Refined rumble. The Gentleman’s Exhaust V2 features custom constructed mufflers, each with a twin tube perforated core design with an updated internal splitter for better flow and a more refined tone that actually lasts.
Built to sound right, not just loud.

Two versions. Same Subie Rumble.
Slide 1: Non-Resonated turns it up a notch
Slide 2: Resonated keeps it refined and balanced
Either way, it’s the Gentleman’s Exhaust V2. Which one would you run?
