Overview
Upgrade the BMW i8 1.5T Hybrid (2014-2020) with a Milltek Sport cat-back exhaust. Milltek builds each system around the car it fits: mandrel-bent T304L stainless pipework, a larger bore than stock for freer flow, and a tuned sound you choose, from quiet and refined to loud and uncorked.
Sound options
- Valved systems let the car switch between quiet and loud.
Sound
Every system on this page is the same type: Valved System - Reuses OE Valve Motor. Milltek lists a single sound type for this car.
Choose your setup
- Optional Downpipe: add a Milltek catted or catless downpipe built to fit this cat-back. Pick Cat-Back Only to skip it.
Cat-back systems: compare every part number
| Part # | Sound | Pipe size | Fit time | Race/Track only |
|---|---|---|---|---|
| SSXBM1241 | Valved System - Reuses OE Valve Motor | - | 3.00 to 4.00 hours | - |
What comes with each cat-back
- SSXBM1241: 1 x Rear Silencer; 1 x Non Valved Outlet Pipe; 1 x Valved Outlet Pipe
Downpipe options: compare every part number
| Part # | Option | Fits with (Milltek) | Stage 2 ECU remap | Race/Track only | Pipe size |
|---|---|---|---|---|---|
| SSXBM1240 | Catted Downpipe (Race/Track only): Required ECU Remap - Fits to OE and Milltek Sport Cat Back Systems | Required ECU Remap - Fits to OE and Milltek Sport Cat Back Systems | - | Yes | - |
"Race/Track only" and "Stage 2 ECU remap" are shown only where Milltek states them. A dash means Milltek does not state it for that part.
What comes with each downpipe option
- SSXBM1240: 1 x Large Bore Downpipe with High Flow Sports Cat
Catted and catless downpipes
A catted downpipe keeps a catalytic converter in the downpipe. A catless downpipe (de-cat) replaces it with a straight pipe. Each option name above says which one it is.
