FAQ

Visual/aural inspection from manifold to tailpipe, CO leak check, backpressure test, hangers/mounts assessment, O2 sensor scan, and a written estimate for repair or replacement—done in-shop for safety.

Louder-than-normal sound, droning on the highway, exhaust smell in the cabin, rattles on bumps, visible rust/holes, hanging pipes, or a Check Engine Light (often P0420/P0430).

No. Leaks can let carbon monoxide enter the cabin and may heat nearby components. Drive minimally and book a same-day check.

Exhaust manifold, gaskets and studs, flex pipe, catalytic converter, resonator, mid-pipe, muffler, tailpipe, flanges, clamps, and hangers/mounts.

Both. We offer quality welding for flanges, hangers, and patchable sections. If structure or emissions components are compromised, we recommend replacement.

Hanger/clamp/weld repair: 30–90 minutes. Cat/resonator/muffler section: 1.5–3 hours. Manifold or seized hardware can add time—we’ll confirm same-day.

Usually a failing catalytic converter or rich fuel mixture. We test fuel trims and O2 sensors to fix the root cause, not just the smell.

A broken flex pipe, cracked flange, or separated muffler shell is common. Winter salt in Toronto accelerates corrosion at weld seams and low spots.

Yes. A restricted cat or crushed pipe increases backpressure; leaks can skew O2 readings. We verify with backpressure and live-data tests.

Absolutely. We service upstream/downstream sensors, clean threads, use anti-seize where OEM-approved, and clear monitors after repair.

We match OEM-like sound unless you request performance tone. We also add/respec resonators to limit highway drone.

Yes—stainless cat-back/axle-back options and mandrel-bent pipes. We’ll balance tone, legal limits, fitment, and budget.

Noise bylaws and provincial regulations can apply. We don’t recommend deletes for street vehicles; we’ll propose quiet performance alternatives.
