🔧 Exhaust Repair Checklist: What to Watch For

Before diving into repairs, inspect these critical areas:

1️⃣ Check for Rust & Corrosion

• Focus on joints, flanges, and hangers—common failure points.
• If pipes are severely rusted, replacement is better than a patch.

2️⃣ Inspect for Leaks & Cracks

• A hissing sound often indicates an exhaust leak.
• Cracks near the turbo or downpipe can cause performance loss.

3️⃣ Verify Mounting & Alignment

• Loose hangers cause excessive vibration, leading to cracks.
• Ensure proper alignment before welding or clamping.

4️⃣ Choose the Right Replacement Parts

• Stainless steel or aluminized pipes last longer than mild steel.
• High-quality gaskets & clamps prevent future leaks.
