PRODUCT DETAILS
RallySport Direct carries a great selection of quality performance exhaust systems and exhaust components brought to you by MBRP.
Here, you are looking at the MBRP 3-Inch Cat-Back Exhaust System. This exhaust system features smooth mandrel bends that limit back-pressure and turbulence. When combined with a larger piping diameter, you get an increase in both horsepower and torque, along with improved throttle response with reduced turbo lag. Everything exits smoothly out of a set of quad exhaust tips that produce an aggressive tone.
DETAILS:
- T304 stainless steel construction
- 3" piping diameter
- Dual split rear exit design
- Carbon fiber tip option
- Race version (no mufflers)
- Loudest version
- Enhanced sound and tone of the boxer engine
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.
