Muffler
Quiets the pulses leaving the engine. Rusts from the inside out because it collects condensation on short trips, which is why the first sign is often a rattle rather than a roar.

Noise, smell or lost power
An exhaust does three things: it gets hot gas away from the engine, it quiets it, and it cleans it. When one of those stops working you usually hear about it first, and the noise tells us a great deal about where to look before the car is even on the lift.
Most exhaust work is smaller than people expect. A rusted section can be cut out and welded, a hanger is minutes, and a heat shield rattle costs almost nothing to fix. The expensive part is the catalytic converter, and that is exactly the part we will not replace without measuring first.
We work on the whole run, from the manifold back: welding, sections, mufflers, flex joints, hangers and converters, on cars, trucks and 4x4s.
If you can smell exhaust inside the car, treat that as urgent rather than annoying. That is carbon monoxide, and it is the one exhaust fault we will always look at the same day.
What the noise is telling us
What we work on
Quiets the pulses leaving the engine. Rusts from the inside out because it collects condensation on short trips, which is why the first sign is often a rattle rather than a roar.
Carry the gas from the manifold back. The flex joint takes engine movement; when it tears you get a ticking under load that sounds like a valve.
Converts the harmful part of the exhaust. Fails by clogging, by rattling internally, or by being stolen. A clogged one strangles the engine and shows up as lost power.
Tell the engine what the mixture is doing. A lazy sensor costs fuel economy long before it turns a light on, and it is a common reason a car fails an emissions inspection.
Hold the whole thing off the floor pan. A broken hanger is the usual cause of a buzz you only hear at one speed.
Where the exhaust starts. A leak here is loudest cold and often quietens as metal expands, which is why it is easy to dismiss.

Weld, replace a part, or replace the system
The usual answer
Muffler, pipe or converter
Last resort
How we find it
Cold first, because manifold and flex-joint leaks are loudest before the metal expands and closes up.
Rust, holes, broken hangers, loose shields and the condition of the joints, with the whole run checked rather than the noisy end.
Backpressure if the complaint is lost power, and sensor data if a code is involved.
You see the hole or the broken hanger, then you get the figure before anything is cut.
What drivers say
I needed a simple brake service, but I did not expect these guys work in the 21st century environment. They communicated with me via detailed text messages, and kept me involved in all decision-making.
Came here for brake pads and rotors. Got a good price, and they did a good job. They did a road test also.
Great service, they got me in same day for full brakes front and back. Definitely recommend.
Exhaust shop near me
Exhaust shop near me, muffler repair near me and muffler shop near me all describe this visit. We weld and replace at Clifton, Franklin, Hawthorne and Newton.
Exhaust noise overlaps with other systems. A rattle that only happens over bumps is often suspension, and lost power with a light on belongs with diagnostics before it belongs here.
Answers to some of the questions KRP Automotive customers ask most. Still not sure? Give us a call, we’re happy to help.
Far less than most people expect when the rest of the system is sound. A single rusted section or a failed joint is usually a weld, and a broken hanger is minutes. We put it on the lift, show you the hole, and quote before anything is cut.
Usually, yes, and it is the first thing we look at. Welding a section is the cheapest honest answer when the rest of the run still has life in it. We will tell you plainly when rust has taken enough of the system that welding is throwing money at it.
A deep roar that built up over weeks is almost always a rusted-through muffler or a hole in a pipe. A noise that appeared overnight is more often a broken hanger or a cracked joint. Both are found on the lift in a few minutes.
Not necessarily, and this is where people get overcharged. A catalyst efficiency code can come from an exhaust leak ahead of the sensor, a lazy oxygen sensor or an engine running rich. We measure backpressure and test the sensors before anyone spends converter money.
Usually not. A loose heat shield or a broken hanger makes exactly that noise, and both are inexpensive. It is still worth fixing, because a system hanging on fewer mounts puts strain on the joints that are left.
Drive with the windows down and bring it in the same day. Exhaust in the cabin means a leak ahead of the passenger compartment, and that is carbon monoxide rather than a noise complaint.
Yes. We weld and fabricate as well as fit direct-replacement parts, so we are not limited to what a parts catalog happens to list for your vehicle.
Our exhaust specialist will weld a section where a section is all that has failed, rather than quoting a whole system because that is the easier job to price.
Most repairs at KRP Automotive are guaranteed for as long as you own your vehicle. If you pay for a repair at our shop, you shouldn’t have to pay for it again, that’s our promise at all four open New Jersey locations.
