PRODUCT DETAILS
RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed.
This is GrimmSpeed's Equal Length Header and has been designed to provide the turbocharger with an uninterrupted flow of exhaust gases to greatly improve the spool response while increasing the horsepower, the torque, all while saving weight. The equal-length layout will produce an aggressive, race-inspired exhaust tone throughout the entire RPM range, and makes for an excellent bolt-on modification. This header will work with the factory turbocharger or factory-like aftermarket turbochargers.
DETAILS:
- 304 stainless steel construction
- Equal-length collectors
- Smooth bends provide an unobstructed flow of exhaust gases leading to the turbocharger
- Improves the spool response
- Increases horsepower
- Increases torque
- Produces an aggressive exhaust tone
- Saves weight by replacing the factory exhaust manifold
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.
