2018 Subaru XV Exhaust Mounts: What They Do and When to Replace
Exhaust mounts (also called exhaust hangers or rubber cushions) are absolutely used on the 2018 Subaru XV. This is confirmed by Subaru’s factory Workshop Manual for the GT/GT7 XV, which specifies multiple rubber exhaust hangers and steel brackets supporting the front pipe, centre section, and rear muffler. The Subaru Electronic Parts Catalogue for MY2018 XV also lists dedicated rubber exhaust hangers and associated brackets for the mid‑pipe and muffler sections, matching what’s shown in general repair manuals that cover the XV/Crosstrek platform.
On the 2018 Subaru XV, the exhaust mounts suspend the exhaust system from the body while isolating vibration and noise. They let the exhaust move slightly as the engine twists and the pipework expands with heat, so the tailpipe stays centred and clear of the bumper, towbar, and rear suspension. Healthy mounts help prevent knocks over rough roads, reduce droning, and keep heat away from trims and underbody components.
As part of routine servicing, it’s smart to inspect the exhaust mounts every 15,000 km or at each scheduled service. Look for perished rubber, cracks, elongation of the holes, or mounts that have gone hard and lost their elasticity. The XV often sees gravel and corrugated roads, and that extra shake can age the rubber quicker. If one mount is failing, replace any neighbouring mounts at the same time to keep the system sitting even. Use quality OEM‑spec rubber or upgraded high‑temp compounds if the vehicle tows or regularly heads off‑road.
- Tell‑tales of worn mounts: thumps on start‑up or over bumps, a low‑sitting or skewed tailpipe, rattles at idle, or the muffler touching the rear valance.
- Replacement tips: let the exhaust cool, support it with a stand, spray silicone lube on the old and new rubbers, transfer any spacers/brackets in the same orientation, and recheck clearances after a short drive.
- Typical service life: highly variable, but many owners replace mounts somewhere between 60,000 and 120,000 km depending on climate and usage.
After fitting, verify there’s clearance to the bumper, heat shields, and rear diff bushes, and that the tailpipe exits neatly. For NZ WOF or Australian rego inspections, secure exhaust mounting is a common check—fresh mounts help the XV pass without drama.
Popular questions
How many exhaust mounts does a 2018 Subaru XV have?
Most 2018 XVs run four rubber mounts—two at the rear muffler and two along the mid‑pipe—though exact count can vary with market spec and accessories. The key is that each section is supported evenly so the system stays centred and quiet.
What are the signs the exhaust mounts on an XV need replacing?
Look for a sagging or off‑centre tailpipe, dull thumps over bumps, rattles at idle, or the exhaust touching the bumper or heat shields. If the rubber looks cracked, shiny from rubbing, or egg‑shaped at the holes, it’s time to swap them.
Can a home mechanic replace the mounts on a 2018 XV?
Yes, it’s a straightforward DIY for most. Work on a cool exhaust, safely support the pipework, use silicone spray to slip the rubbers off and on, and keep the brackets in the original orientation. If the exhaust has shifted a long way, a workshop alignment is worth it.
