Transform the rear of your BMW G45 X3 30e with the Deep Tone Industries Quad Exhaust Tailpipe Conversion, developed to give the plug-in hybrid X3 a more purposeful four-tailpipe appearance when fitted with the BMW X3 M50 M Performance rear diffuser.
The standard G45 X3 30e does not feature the same visible quad exhaust arrangement as the M50. This Deep Tone Industries conversion provides a dedicated solution for owners who want to combine their 30e with the more aggressive M50 rear diffuser while adding four visible exhaust tailpipes to complete the conversion.
Two tailpipe finishes are available, allowing you to tailor the final appearance of the rear end:
-
Polished Tailpipes
-
Carbon Fibre Tailpipes
Designed specifically around the BMW G45 X3 30e, the kit is backed by a fitment guarantee and a 1-year warranty for the original purchaser.
Please note: installation requires the M50 BMW M Performance rear diffuser, which must be purchased separately.
Key Features
-
Designed specifically for the BMW G45 X3 30e
-
Converts the rear to a visible quad-tailpipe layout
-
Four exhaust outlets
-
Designed for use with the M50 rear diffuser
-
Choice of polished or carbon fibre tailpipes
-
Creates a more performance-focused rear appearance
-
Vehicle-specific fitment
-
Fitment guarantee
-
1-year warranty for the original owner
-
Ideal for G45 X3 30e M50-style rear conversions
Quad Exhaust Conversion For The BMW G45 X3 30e
The latest G45 X3 has a clean, modern rear design, but the standard X3 30e doesn't receive the same exhaust outlet treatment as the more performance-focused M50.
For owners upgrading to an M50-style rear diffuser, this can leave the exhaust as the missing piece of the conversion.
Deep Tone Industries has developed this quad tailpipe setup specifically to address that problem.
The conversion introduces four visible exhaust outlets, creating a wider and more purposeful appearance that better complements the openings and design of the M50 rear diffuser.
Designed For The X3 M50 Rear Diffuser
This exhaust tailpipe conversion is specifically intended to be installed alongside an M50 rear diffuser.
The original X3 30e rear bumper configuration does not provide the required layout for the quad exhaust tips, so the corresponding diffuser conversion is an essential part of the installation.
For the complete setup, we recommend the:
Genuine BMW G45 X3 M Performance Aramid Rear Diffuser
This must be purchased separately and provides the correct rear styling configuration for the quad exhaust conversion.
Required M Performance Rear Diffuser
The M50 M Performance rear diffuser is required and is not included with this product.
The corresponding Genuine BMW component can be purchased from R44 Performance:
Genuine BMW G45 X3 M Performance Aramid Rear Diffuser – 51125B8AF54 / 51125B4D662
Using the correct diffuser is essential to achieving the intended fitment and positioning of the quad exhaust outlets.
Polished Tailpipe Option
Choose the polished exhaust tips for a classic performance exhaust appearance.
The bright metallic finish creates a strong contrast against the darker lower section of the rear bumper and diffuser, making all four exhaust outlets clearly visible.
This option works particularly well for customers who prefer a more traditional performance exhaust aesthetic or want the tailpipes to stand out as a feature of the conversion.
Carbon Fibre Tailpipe Option
For a darker and more contemporary appearance, select the carbon fibre tailpipe option.
Carbon tips complement the performance-focused materials and detailing of the M Performance rear diffuser, giving the conversion a more premium appearance.
They are particularly well suited to G45 X3 builds already featuring carbon fibre or dark exterior styling components.
Which Tailpipe Finish Should I Choose?
Both configurations provide the same fundamental quad-tailpipe conversion, so the choice comes down primarily to the appearance you want to achieve.
Polished – brighter, more traditional performance exhaust appearance with greater contrast against the diffuser.
Carbon Fibre – darker, more modern finish that pairs particularly well with carbon and M Performance exterior components.
Either option transforms the X3 30e from its standard exhaust presentation to a much more noticeable four-tailpipe layout.
Complete The G45 X3 30e M50-Style Rear Conversion
The combination of an M50 rear diffuser and quad exhaust outlets creates a much more comprehensive rear-end transformation than changing the diffuser alone.
Together, the components address both major visual elements of the lower bumper:
-
The shape and design of the rear diffuser
-
The positioning and appearance of the exhaust outlets
This makes the Deep Tone Industries conversion particularly relevant for owners already planning to install an M50 or M Performance-style rear diffuser on their X3 30e.
BMW G45 X3 30e Compatibility
Designed specifically for:
-
BMW G45 X3 30e xDrive
-
Plug-in hybrid models
-
Vehicles converted to the compatible M50-style rear diffuser
Important: This kit is designed around the X3 30e and should not be assumed to fit other G45 X3 engine variants.

We recommend using the Genuine BMW M Performance Aramid Rear Diffuser for the intended fitment and appearance.
Any additional installation requirements should be assessed by your chosen installer before work begins.
Professional Installation Recommended
Professional installation by a BMW or exhaust specialist is recommended.
Correct installation is important to ensure the four tailpipes are positioned evenly within the diffuser openings and maintain appropriate clearance from the surrounding bodywork.
During installation, particular attention should be paid to:
-
Tailpipe alignment
-
Equal left-to-right positioning
-
Exhaust clearance
-
Diffuser clearance
-
Secure mounting
-
Heat clearance around surrounding components
The system should be checked again once installed and brought up to operating temperature.
Fitment Guarantee
The Deep Tone Industries Quad Exhaust Tailpipe Conversion is supplied with a fitment guarantee, giving customers additional confidence when purchasing a vehicle-specific conversion for their G45 X3 30e.
Correct fitment relies on the vehicle using the intended compatible M50-style rear diffuser and being installed correctly.

The warranty applies to the original purchaser and provides additional reassurance alongside the vehicle-specific fitment guarantee.
Full warranty coverage remains subject to the manufacturer's applicable warranty terms and correct installation and use of the product.
