WHAT DOES A MUFFLER DO?Located under the vehicle, the muffler is a key part of a gas-powered vehicle’s exhaust system. Attached to the tailpipe, the muffler is designed to quiet the sound of the engine as emissions pass out of the vehicle. The muffler can also enhance performance by getting rid of all of the exhaust gases and taking in oxygen faster to generate power. Featuring a set of tubes with tiny holes, these tubes inside the of the muffler reflect sound waves. As the sound waves bounce around, they cancel each other out to reduce the engine noise before they’re routed out of the vehicle through the exhaust tailpipe. |
ALUMINIZED VS. STAINLESS STEEL MUFFLERSDeciding between an aluminized muffler and a stainless-steel muffler could come down to where you live and appearance. Aluminized mufflers are a good option if you live in a warm climate that doesn’t get much snow and ice. While an aluminized muffler can survive in snowy climates, road salt can cause premature rusting. Stainless steel mufflers, on the other hand, deliver enhanced corrosion protection and might be worth the investment if you live in a snowy climate where salt is used on the roads. Another factor can be appearance as some prefer the look of a stainless-steel muffler, especially a polished stainless-steel muffler. |
UNIVERSAL VS. DIRECT FITKnow the goals for your exhaust repair can help you choose between a direct fit muffler and a universal muffler. Direct fit mufflers are designed to bolt on your vehicle with no modifications or fabrication during the installation process. Using the specs and space constraints for the vehicle its designed for, a direct fit muffler is engineered to fit and perform like the original part. Universal mufflers are ideal for performance and vintage applications where the ability to customize the exhaust system is needed. You’ll likely need to make modifications including welding and/or fabrication. |
SIGNS OF A FAILING MUFFLERMufflers primarily deteriorate from the inside out due to the acidic moisture produced by the combustion process. Signs that it may be time to replace your muffler include: unusual noises coming from the muffler, a foul odor in the cabin from the muffler not properly filtering exhaust gases, distorted body shell and reduced gas mileage from a failing muffler causing the engine to work harder and use more fuel. |

This isn't the cheapest muffler, or the highest flowing in it's rice range. It's given me a little more sound from the 4.0L I6 engine, not extremely deep or throaty, but that's due to the tailpipe itself not being modified. Please note that on the Wranglers, you need to make sure the transmission is supported if you attempt to remove the skid plate to access this area. The skid plate holds it in place and it will cause severe damage and a big headache if you don't support it (I found out about this through a Jeep forum before purchasing or attempting the install).
This muffler sounds a little better, but does have a mild sound with some minor droning. The minor droning is the only reason this doesn't have a 5 star rating but it's close enough to consider it a 5 star for me I guess. That's only noticeable when driving at speeds below 30 MPH, and surprising not much of it at idle. The throttle and power are mildly improved over the stock setup, but a higher flow catalytic converter would make that jump more I believe.
The biggest improvement is to the mileage. The mileage I get is as follows:
Stock setup: 9.6-12.0 MPG City / 10.7-12.5 MPG Highway (hovering around 55-60MPH for efficiency)
With K&N Intake installed: 12.2-14.9 MPG City (24% improvement)/ 13.5-15.3 MPG Highway (14% improvement)
With Intake and Dynomax muffler: 13.9-16.1 MPG City (34% improvement over stock, 8% over Intake install) / 15.2-17.9 MPG Highway (43% improvement over stock, 17% increase over Intake install)
Consider this, the Wrangler holds 19 gallons of fuel. This meant I could originally go at most (17 X 12.5 = 213) miles, but now have a maximum range of (17 X 17.9 = 304) miles. That's an additional 91 Miles highway driving (figure about 64-68 additional city miles). Compare to the mileage, so divide by MPG, and that's a fuel savings of 5.01 gallons Highway, and 4.09 gallons City. At about (we guess low cost for this) $3.25 per gallon, this is a savings of $16.28 Highway, and $13.29 each tank of gas, compared to how many gallons you would have originally spent to drive as far. The savings literally help pay for the product and install. I actually used this to save the money I would have spent on extra gas to save for additional items for maintenance after it had offset the cost of the items themselves.
Do yourself a favor and install something like this on your vehicle, but make sure to research a little into your current specs so you are aware of how it changes the way your vehicle performs.
