Parts for your 2007 Subaru Legacy-Exhaust mount

2007 Subaru Legacy exhaust-mount

Yes, an exhaust-mount is absolutely used on the 2007 Subaru Legacy. Technical references including the Subaru Factory Service Manual for 2005–2009 Legacy/Outback (Exhaust section), the Subaru FAST parts catalogue (listing the exhaust “insulator”/mounts), and the Haynes Subaru Legacy & Outback 2003–2009 manual all identify multiple rubber exhaust hanger insulators supporting the front, centre and rear sections of the system. So it’s a relevant, serviceable part on every 2007 Legacy variant.

On this model, the exhaust-mounts are the rubber insulators that suspend the exhaust under the car. They do three key jobs: carry the weight of the system, isolate engine and road vibration from the cabin, and allow the pipes to expand, contract and move slightly without hitting the body. When they harden, crack or tear, the exhaust can sag or knock against heat shields, crossmembers or the rear bumper.

As part of routine servicing, it’s smart to give the mounts a quick look every 10,000–15,000 km, especially on cars that see coastal conditions or lots of short trips. Anyone noticing a tinny rattle at idle, a thud over bumps, or a tailpipe that sits off-centre should suspect tired mounts.

• Tell-tales: perished or split rubber, elongated holes, shiny contact marks on the exhaust or underbody, and excessive movement when the system is gently rocked by hand.
• Replacement approach: support the exhaust with a jack and wood block, lube the old mounts with silicone spray, then lever them off the pegs with exhaust-hanger pliers or a flat screwdriver. Fit quality OEM-style rubber insulators, polyurethane options add firmness but can increase cabin vibration.
• Good practice: replace mounts in pairs or as a set so the system sits level, check nearby brackets and heat shields, and ensure adequate clearance around the subframe and bumper on refit.

On the 2007 Legacy, a tidy set of fresh mounts can transform refinement—quieter idle, fewer knocks, and proper alignment of the muffler tips. It’s an inexpensive, driveway-friendly job that helps protect flex joints, gaskets and welds from extra stress, especially on turbo variants or cars with heavier aftermarket cat-backs. For most owners, periodic inspection and replacement as needed is all that’s required to keep things sweet under the floorpan.

Popular questions about 2007 Subaru Legacy exhaust-mount

How many exhaust-mounts does a 2007 Subaru Legacy have?
Most cars of this generation run four to six mounts, depending on sedan vs wagon and single vs twin rear mufflers. Turbo models and some aftermarket systems may add or relocate hangers. A quick visual check on a hoist or ramps will confirm the exact count on a given car.

Should they use OEM rubber or polyurethane mounts?
OEM-style rubber is the safe bet for daily driving—it controls movement while keeping noise and harshness low. Polyurethane is firmer and great for performance or heavier exhausts, but it can transmit more vibration into the cabin. Many owners fit OEM at the front and centre, with a firmer option at the rear if the muffler is heavy.

Is it okay to drive with a broken exhaust-mount?
It’s not ideal. A missing or torn mount can let the exhaust droop or knock, stressing flanges, flex joints and welds. A short, gentle trip to a workshop is usually fine, but it should be fixed promptly. Temporary tie-ups are only for getting home—proper mounts are cheap and designed to flex safely.
