Issue 17 — Detroit, Michigan
The Loud Issue
Mufflers, custom exhaust, catalytic converters and check-engine lights — fixed by ASE-certified technicians in a Detroit shop that’s been bending pipe since 2009. A free exhaust check with every visit.
Typical idle readings, a foot and a half from the tip — every car sounds different. Michigan requires a working muffler, and every system we build keeps one.
We’ll make it as loud as you want. We’ll never make it leak.
Dee Marchetti, owner
Lead story — how we work
Loud is a choice. Leaking isn’t.
Every exhaust that comes through our door gets the same first ten minutes: up on the lift, a hand along the pipe, a smoke test if anything’s in doubt. Half the time the fix is a $40 hanger or a clamp, and that’s all you pay for. When it is the muffler, we show you the hole before we quote. If you want it louder — a straight-through muffler, a resonator delete, a full cat-back — we’ll build it in stainless and keep it street-legal, because Michigan requires a working muffler and nobody likes a ticket. And a leaking exhaust isn’t a sound problem: it can put carbon monoxide in the cabin. That part we take seriously, every time.

To the shop —
Two shops told me I needed a whole new exhaust. Loudhouse put it on the lift, found a hanger that had let go, charged me $38 and had me out in twenty minutes.

To the shop —
Asked for loud-but-not-obnoxious on my Mustang. Andre built a stainless cat-back that’s exactly that — and my neighbors still wave at me.
Luis G.2018 Ford Mustang GT · custom cat-back
To the shop —
Check-engine light for three months. Rosa traced it to a cracked manifold gasket, not the converter the dealer wanted to sell me. Saved about $1,100.

To the shop —
I could smell exhaust with the windows up. They found a rusted flex pipe in ten minutes, welded in a stainless one and the smell was gone that afternoon.

Ask the shop
Real questions from the counter, answered by the people who weld.
Q.01Is a loud exhaust legal in Michigan?
Michigan requires every car to have a working muffler and prohibits excessive noise, so we build loud, not lawless: every system we sell keeps a working muffler, and we’ll tell you honestly if a build is likely to draw attention.
Q.02Why is my check-engine light on after an exhaust leak?
A leak ahead of the oxygen sensors lets in outside air, and the engine computer reads it as running lean. Fix the leak and the light usually goes out on its own after a few drives.
Q.03Do I really need a new catalytic converter?
Maybe not. We test it first — temperatures, sensor readings and backpressure — because a failing sensor or a leak often looks like a bad converter. The $95 test is credited to the repair.
Q.04Can you make my car quieter?
Yes — that’s half our work. A new muffler, a resonator, or a chambered muffler in place of a straight-through one brings most cars back to factory-quiet.
Q.05How long does a custom exhaust take?
Most cat-back systems are bent, welded and fitted in a day. Drop it off in the morning and hear it on the way home.
Q.06Is an exhaust leak dangerous?
It can be. A leak under the cabin can let carbon monoxide inside, especially with the windows up in winter. If you smell exhaust in the car, come in — the check is free.
Q.07Do you work on trucks?
Gas trucks and SUVs, yes, dual exhausts included. Diesel particulate filters and DEF systems we send to a diesel specialist we trust.
