PRODUCT DETAILS
RallySport Direct is proud to carry the Go Fast Bits TMS Respons Hybrid Blow Off Valve. This makes for an excellent upgrade over the stock blow off valve to hold more boost and to have a quicker response.
DETAILS:
- Patented adjustable venting bias system found in the Stealth FX system
- Allows you to control the amount of air that is vented to the atmosphere, or recirculated back into the intake to control the venting sound based on driver preference
- You can achieve a vented blow-off valve sound without triggering a check engine light or other problems such as running rich or stalling
- New hardware and tool will be provided to make this blow-off valve ready for the installation
WHY WE CARRY THIS
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
