Magnaflow 11226 vs 11385: A Fleet Buyer’s Comparison, Plus the Sidecar OBD Scanner and Other 2025 Add-Ons

Why I Compare Magnaflow Mufflers Like I Compare Vendors

I’m not the technician in the bay. I’m the person who approves the repair order after the truck is back in service. I’ve worked as a procurement manager at a 38-person fleet services company for six years. We spend roughly $210,000 per year on vehicles, parts, and repairs, and I document every order in our cost system.

In Q1 2025, two work trucks needed exhaust work. Both drivers asked for “a Magnaflow.” That kept the brand argument short, but it did not answer the actual question: 11226 or 11385.

The Magnaflow Performance Exhaust Muffler 11226 and the Magnaflow Performance Exhaust Muffler 11385 look close in online listings. The prices are close too. The more important comparison is how each one behaves in a truck that works for a living.

My comparison framework was the same one I use for any supplier: sound and driver fatigue, physical fit, total installed cost, and the risk of doing the job twice. Actually, the last point should be first. If a part fails at month 14, the original quote doesn’t matter.

Sound: The Quieter Choice Wasn’t the Boring Choice

We put the 11226 on a regular-cab 2016 6.0L truck. We put the 11385 on a crew-cab 2017 6.0L truck. I’ll admit that is not a lab-controlled test. But for a fleet manager, repeated driver feedback is data.

The 11226 has the classic Magnaflow bark. On cold start it sounds purposeful. Under load, however, the cab gets a lot of exhaust noise, especially with the windows up and a trailer behind. My first driver loved it for one week. Then he stopped loving it on a 200-mile run.

The 11385 still has the Magnaflow tone, but it is smoother. I would not call it quiet. I would say it is less harsh. After the same 200-mile route, the driver did not complain. That mattered more than the subjective “cool” factor. In my opinion, a quieter work truck is often a better work truck.

Installation: The Part Number Is Only Half the Quote

On paper, the 11226 looked like the easier install because its case sat closer to the factory can dimensions. The 11385 had a different case profile, and the exhaust shop needed to adjust the tailpipe hanger on our truck. That added one line item to the invoice.

I told the shop “just get it done before the inspection appointment.” They heard “make it fit without asking for approval.” Result: they did make it fit, but the extra hanger work showed up on the invoice anyway. In retrospect, that was a communication failure on my side. I should have approved a hanger charge before it became a surprise.

Total Cost: It Was Not Just the Price Difference

Our March 2025 distributor quote listed the 11226 at $54 less than the 11385. After installation, the total difference between both invoices was larger because the 11385 needed that hanger adjustment. If I had compared only part prices, I would have made the wrong decision.

I want to say the final difference was around $119, but don’t quote me on that. Our cost system splits labor and parts across two different job codes. The real point is this: verify current Magnaflow pricing before you order, and get an install quote that includes hanger or pipe adjustment.

I don’t mind paying for a reliable fit. I do mind surprise work. The cheapest part is only cheap if it lands, fits, and stays put.

What Surprised Me About the 11385

I started this comparison expecting to choose the 11226 because it was more aggressive and less expensive. After tracking complaints, the 11385 won the actual test: no drone complaint, a happier driver, and the same towing behavior as before. I will not claim a horsepower gain, because I did not measure one. On a stock 6.0L work truck, a muffler swap is maintenance, not racing.

It took me six years and roughly forty exhaust-related repair orders to understand that the “best” part is the one that does not put the truck back in the shop. That sounds obvious, but it is not what most internet comparisons measure.

The Rest of That 2025 Purchase Order

Exhaust was not the only thing on the Q1 list. The same purchase order included three smaller additions that all earned their place through comparison.

Sidecar OBD Scanner

After the exhaust install, I used a Sidecar OBD Scanner to log idle quality and make sure no check-engine light returned. It is not a replacement for a professional bidirectional scan tool. I won’t oversell it. What made it useful was the app’s saved vehicle profiles. Our shop staff could plug it in, read the same readiness data I would have pulled, and send me a report. For a small fleet, that cuts diagnostic guesswork without adding another expensive scan tool to the toolbox.

Chrysler Pacifica Bug Deflector

I also ordered a Chrysler Pacifica Bug Deflector for the Pacifica that does weekly highway parts runs. At first I treated the deflector as cosmetic. Then I looked at the front edge of the hood and the number of windshield chips on that vehicle. The deflector won’t stop everything. It did keep most of the high-speed bug debris away from the wiper tray. It was a small insurance policy, and the only surprise was that we didn’t add it when the van was new.

The Best Portable Air Compressor 2025 Review That Matters

I also ran my own best portable air compressor 2025 review. It was one page, no ads, and it ended with a unit that has a replaceable pressure switch. The previous compressor died at minute 22 of a tire inflation job because the switch wasn’t available locally. This year’s pick has an accessible switch and a replaceable chuck. In my opinion, that makes it the best portable air compressor for a working fleet, even though a cheaper unit comes with more impressive marketing numbers.

Bottom Line: Magnaflow 11226 vs 11385 in a Fleet Budget

If the truck makes long highway miles, I would choose the Magnaflow Performance Exhaust Muffler 11385. It is less tiring, and the fit issue we saw on our truck was minor. If the truck is a short-run vehicle and the driver wants the louder Magnaflow personality, the 11226 is fine. Just do not choose it only because the sticker is lower.

If you manage parts or vehicles the way I do, get the full install quote first. On an old work truck, the real comparison is not 11226 vs 11385. It is whatever gets the vehicle back to work once, without a second trip to the shop.
