Body kit II middle exhausts Mansory Carbon for Audi RS Q8

Body kit II middle exhausts Mansory Carbon for Audi RS Q8

Body kit II middle exhausts is the second exhaust-architecture variant inside the genuine Mansory Carbon Fiber Body kit set for Audi RS Q8 programme — the version where the four 4.0-litre TFSI biturbo V8 tailpipes are routed through the rear diffuser as a central twin-pair cluster, rather than splayed to the outer corners of the bumper as in Body kit I. The recipe is otherwise identical: a full carbon front splitter, integrated race flaps, side skirts and a redesigned rear diffuser sit on the 4M chassis around the 600 hp / 800 Nm SUV-coupe with its 48 V mild-hybrid, quattro AWD, RS-tuned air suspension and 22- to 23-inch wheel envelope. Owners specify II when they want the centred quad-tip silhouette to dominate the rear three-quarter view, with the diffuser fins working as a frame around the exhaust theatre.

Construction & Materials

Every shell in this kit is laid by Mansory in autoclave-cured prepreg carbon. The diffuser around the central exhaust cluster carries an extra inner heat-deflector layer — necessary because the four tips now exit through a tightly bundled central tunnel rather than dispersing heat to the outer bumper corners.

• 3K twill outer ply on visible faces; biaxial inner plies for stiffness behind the diffuser fins.
• Autoclave cure under 6–7 bar; the central exhaust shroud receives an additional thermal-barrier ply.
• Wall thickness 1.8–2.4 mm depending on panel; 3.2 mm at the diffuser fin roots and around the tip cut-outs.
• Total kit-mass delta versus OEM bumpers and trims: approximately 11–13 kg saved.
• Mounting: OEM Audi bumper bolts retained; race flaps via M6 stainless threaded inserts; side-skirt extensions on 3M VHB plus four hidden brackets per side.
• Finish options: gloss UV-stable lacquer (default), matte 2K satin, or raw-weave wax-sealed; central exhaust shroud always satin-finished to mask soot accumulation.
• Stainless heat-shielding mesh behind the central diffuser cut-outs to protect the carbon edge from tip-radiated heat at idle.

Design & Visual Function

The defining feature of II is the rear diffuser. Where Body kit I keeps the OEM-style outboard tip layout, II machines two adjacent twin-tip ports straight down the bumper centreline, separated by a vertical carbon spine. The visual effect is closer to the Mansory Venatus rear treatment — a dense, motorsport-derived signature that pulls the eye to the middle of the car instead of letting it spread to the corners. The fin geometry has been re-spaced to reflect that change: fins step outward from the central cluster at progressively wider intervals, creating a chevron that points the gaze back toward the tips.

Up front, the splitter and race flaps are shared with Body kit I. The splitter's leading edge sits roughly 35 mm forward of the OEM bumper apex, with cooling cut-outs aligned to the side intercoolers behind the front fenders and a central scoop feeding the V8's main radiator. Side skirts continue the splitter's lower plane uninterrupted along the rocker, then transition into the rear diffuser fence so that air leaving the underbody is funnelled through, not around, the central exhaust cluster.

Heat management was the engineering driver for Body kit II. With four tips condensed into the centre, exhaust gas leaves a smaller area at higher local temperature; the diffuser shroud uses a stepped geometry to keep tip surfaces 30–40 mm clear of carbon edges at all running conditions, and an internal aluminised heat shield extends 220 mm forward of the tip exits to capture radiated heat before it can soak into the diffuser body.

Compatibility & Fitment

Audi RS Q8 (4M chassis), MY 2020 onward — pre-facelift 2020-2023 and facelift Performance 2024+. Two diffuser back-plates are produced because the facelift's slightly raised rear-bumper crash-beam mount sits 8 mm higher than pre-facelift; specify VIN at order so the correct plate is supplied. The kit retains OEM Audi parking-sensor housings (six rear), the rear ACC corner radars, and the bumper-flap drive-mode actuators where fitted. The central exhaust geometry assumes an OEM RS Q8 manifold-back system or a centre-routed Mansory MTC sport exhaust; aftermarket side-exit systems are not compatible without manifold work.

Installation & Reversibility

Full kit fit requires a body shop with a four-post lift and around 16 working hours: 4 hours front bumper, 5 hours diffuser plus heat-shield routing, 3 hours skirts, 4 hours paint match and finish. The car is brought up on standard lift mode of the air suspension to clear the splitter under-tray. Carbon parts arrive primed for the chosen finish; if matching to OEM body colour, a full-base colour-cycle is applied at the shop. Every panel is bolt-reversible — the kit removes back to OEM bumpers and diffuser without any drilling into structural metalwork. Race flap mounting points are concealed behind the splitter's leading edge so that, if removed, the splitter face shows no exposed inserts.

Pairing within the Mansory RS Q8 programme

Body kit II is offered as a complete set, but several genuine Mansory carbon pieces from the same Section A line extend the programme. Most owners specifying II then go on to add the rear-decklid spoiler II to balance the central-exhaust theatre at the trunk's trailing edge: Rear decklid spoiler II Mansory Carbon for Audi RS Q8. If the kit's diffuser/spoiler geometry is the goal but the four central tips are not — e.g. on cars with a sport exhaust kept in the OEM outboard layout — the standard Body kit Mansory Carbon for Audi RS Q8 is the equivalent set with side-exit cut-outs (Body kit II differs from Body kit I only in the diffuser exhaust routing). For the rear bumper alone, the matching Rear bumper splitter Mansory Carbon for Audi RS Q8 can be ordered as a separate piece if the front splitter and race flaps are already on the car.

Maintenance & Durability

The lacquered carbon is engineered for an outdoor lifespan beyond ten years if maintained correctly. Wash with pH-neutral shampoo, two-bucket method; never let alkaline wheel cleaners or ammonia-based glass products contact the diffuser around the exhaust shroud, since heat-cycled lacquer is more chip-prone there. A ceramic coating in the 8H–9H range is recommended on the diffuser specifically — the central tip area sees soot deposition that, over a season, etches uncoated lacquer. Stone-chip propagation from the splitter leading edge is repaired with an epoxy fill and local UV cure; PPF over the splitter face is a sensible factory-add. The central exhaust shroud is replaceable as a single sub-assembly without dismounting the rest of the diffuser, in case of rare heat-soak damage.

Lead Time & Warranty

Lead time 5–8 weeks. The central exhaust shroud is produced in a separate cure cycle from the diffuser body, which adds about a week to the pure Body kit I timeline. The kit ships in five crates — front bumper assembly, race flaps, two side-skirt crates, rear diffuser plus shroud, decklid spoiler — with VIN-matched fitment notes inside crate one. 12-month warranty against manufacturing defects: delamination, cure voids, lacquer failure not caused by chips or chemical attack.

FAQ

Q: What is the actual difference between Body kit I and Body kit II?
A: Only the rear diffuser. Body kit I keeps the four exhaust tips in the OEM-style outboard arrangement; Body kit II routes them as a central twin-pair cluster down the bumper centreline. Front splitter, race flaps and side skirts are identical between the two kits.

Q: Do I need to change the OEM exhaust system to fit Body kit II?
A: No, the kit is compatible with the standard RS Q8 manifold-back system, which is already a centre-merged layout. A Mansory MTC centre-routed sport exhaust is offered as an option. Aftermarket side-exit systems will not align with the central diffuser cut-outs.

Q: Will Body kit II fit my facelift Performance 2024?
A: Yes. There are two diffuser back-plates — pre-facelift and facelift Performance — to account for the 8 mm higher rear-bumper crash-beam mount on the facelift. Send the VIN at the order stage.

Q: How hot does the central exhaust shroud get?
A: Surface temperatures on the inner shroud reach roughly 180–220 degC during sustained high load; the design positions the carbon edges 30–40 mm clear of the tips at all running conditions, and the aluminised heat shield blocks radiated heat before it reaches the diffuser body.

Q: Is the kit removable without trace?
A: Yes. Every panel uses OEM bolt patterns or hidden brackets; no structural drilling is required. Reverting to OEM bumpers and diffuser leaves only the small race-flap inserts behind the (then-removed) splitter, which are not visible from outside the car.
