BMW F90 M5 Equal Length Mid Pipe

BMW F90 M5 Equal Length Mid Pipe

This Equal Length Mid Pipe replaces the restrictive factory centre section of the BMW F90 M5, removing a significant flow bottleneck between the downpipes and the rear exhaust.

The factory mid section is heavily silenced and unequal in length between banks. This system runs matched length pipes to both sides, which allows the two banks of the S63 to scavenge evenly and produces a noticeably cleaner, more even V8 tone with far less muffling.

It is the natural middle component of a full exhaust build. Fitted with the factory rear exhaust it lifts volume and sharpens the note considerably. Fitted alongside downpipes and a catback it completes the system and removes the last restriction in the path.

Manufactured from 304 stainless steel with a mirror polished finish and precision TIG welded throughout, using the factory mounting points and clamp positions for a direct bolt on installation.

For an F90 owner chasing genuine flow gains rather than volume alone, this is the component most systems leave out.

Key Features

Equal Length Design

Matched pipe lengths to both banks allow even scavenging and produce a cleaner, more even V8 note than the factory unequal length section.

Removes a Major Restriction

The factory centre section is heavily silenced. Replacing it frees up flow between the downpipes and the rear exhaust.

304 Stainless Steel Construction

Corrosion resistant stainless steel built to withstand sustained high exhaust gas temperatures.

Mirror Polished Finish

A clean, high quality finish throughout the visible sections of the system.

Precision TIG Welded

High quality welds engineered for demanding performance use and full pressure testing before dispatch.

Direct Bolt On Fitment

Uses the factory mounting points and clamp positions, with no cutting or welding required.

Performance Benefits

• Removes the restrictive factory centre silencer
• Even scavenging between banks through equal length pipes
• Increased exhaust flow efficiency
• Cleaner and more even V8 exhaust tone
• Increased volume with the factory rear exhaust retained
• Completes the exhaust path when paired with downpipes and a catback

Performance gains may vary depending on ECU calibration and supporting modifications.

Please Note

Professional installation is strongly recommended.

This is a mid pipe only. Downpipes and the rear exhaust section are not included.

Removing factory silencing will increase cabin noise. Sound characteristics vary considerably depending on which other exhaust components are fitted.
