Description

The Stealth Cat-Back is our quietest full-system build for the Mk7 and Mk7.5 GTI: a hand-built 3" dual-exit cat-back engineered for the OEM+ crowd who want a deeper, cleaner note with the drone completely dialed out. Three separate stages of sound control across the system make this the sleeper setup: aggressive when you're in it, dead quiet at a highway cruise. Fully TIG-welded, argon back-purged 304 stainless, built to order.

Triple-silenced: the stealth sound package

  • Mid-pipe section, Vibrant 17950 resonator. A 3" resonator up front smooths the note right off the downpipe.
  • Front muffler section, Stainless Bros 3" thin oval muffler. Mounted ahead of the rear diff, it knocks down the mid-range without choking flow.
  • Rear axle-back section, Vibrant 10635 StreetPower transverse oval muffler. A single 3.5" inlet splits into a true dual 3" exit, so the rear stays clean and drone-free.

Why this cat-back

  • True 3" dual-exit system. One continuous 3" path from the downpipe connection all the way to the tips.
  • Jones double-wall tips (optional). 3" inlet, 4" outlet, slant-cut, laser-etched Brockett Built logo, slip-fit. Choose Without Tips if you'd rather run your own.
  • 304 stainless, TIG-welded and back-purged. Clean, fully fused welds inside and out: no flux, no porosity, no rust-through at the joints.
  • Bolt-on. V-band and slip-fit connections, factory hanger locations, no cutting.
  • Lifetime warranty. Same as every Brockett Built exhaust: if a weld or material fails, we replace it.

Fitment

  • VW Mk7 GTI: 2015, 2016, 2017 (front-wheel drive)
  • VW Mk7.5 GTI: 2018, 2019, 2020, 2021 (front-wheel drive)
  • Engine: EA888 Gen 3 2.0T, IS20 turbo
  • Select your chassis above. The rear section is built to match your car's factory valance and exit. Bolts to a 3" downpipe connection.

Pairing with a downpipe?

Run this behind our V2 catted 3" downpipe for a complete, CEL-free turbo-back.
