Muffler Showdown! What's the Best Muffler for Your Engine? | Engine Masters | MotorTrend

[@chriswise1232]

This needs to be a regular segment every year with all the newest mufflers to the market.

[@griffittsgarage]

Because of this show, I installed a single 3” hooker maximum flow on my 5.9 Dodge Ram van with a 3” tail pipe over the rear end. Super happy with how it sounds and feels!! Just did a 2000 mile road trip and couldn’t be happier! Thanks fellas

[@LordSaliss]

I would really like to see a comparison with the same engine (345hp V8) and exhaust size (2.5") used in all tests, and test the different TYPES of mufflers, not just brands of mufflers. So glasspack (magnaflow) vs chambered (flowmaster) vs turbine (jones or aero) vs turbo (pypes or jones) vs spiral flow (moroso). Maybe even throw one of Flowmaster's Super HP-2 laminar flow mufflers in as well for good measure. Track the max HP and torque, as well as the max dB from the exhaust pipes, and have an audio recording of each muffler tested so users can give them a listen and find their subjective tastes.

Yeah but it be ridiculous to drive constantly. A Good muffler reduces noise without creating back pressure

Glass packs work in tight places, traditional sound. I like em right off the headers. They burnout faster, then they sound better. I think the Dynomax race magnum series are great, but they do have some drone down low off idle.

[@andrewn.3660]

Awesome episode. I have a 09 G8 and the hooker maxflows have changed the game for me. Not only were they much quieter than the kooks mufflers, but they made 2hp more on the dyno. And the lower end actually improved by a max of 5hp/4lb ft. I love them. This test just proves I made the right choice when I picked them up. Quantification at its finest

[@chehystpewpur4754]

look im just gonna comment because he was loving that flowmaster muffler so hard. its the truth. i bought some flo pro mufflers for my vortec sbc build last year. they are flow pro super v mufflers. flo pro makes great exhaust for diesels at a good price. they got into gas motors because people love their products. i got 2 2.5" super v mufflers for 70 bux shipped. they lasted 20k miles and i drove it in winter and didnt want to because its a clean car. the mufflers are fine. they are super strong and do not take damage. i bet the flowmasters are a little better metal. but flo pro super v is just as good and less money. makes a deep sound. quiet till half throttle. no rasp. you cant hear your cam chopping. just low deep glug or blub sound but it sounds like power. same motor with open headers sounds like a potato cam. very nice sound nobody has complained yet about it they all love the sound. i hope someone sees this and tries them because its a lesser known with the gas motor guys brand and im acutally very happy with them. ill buy mufflers from them now for a long time.

[@zacksalmon65]

Wowza. The cheapest muffler (Hooker) made the best HP, basically equal to the best torque, and yet was almost the quietest. Clear winner IMO. Granted, this analysis leaves out the main point of a muffler....the sound. Couldn't really tell without hearing it in person.

[@ghunt81]

If I'm not mistaken, the Thrush they test in the first part of the video is an old school turbo style muffler so not surprised that it makes less power.

Id go for the one with the best sound quality. With 1060 HP, nobody could tell an adfitional HP. It would all be phycological and the loudest one would feel the most powerful even if it was in last place.

I ran 2 1/4 inch Dynomax Super Turbo mufflers on my 1990 Mustang GT. Timing was at 12° BTDC, off road H-pipe and K&N air filter with air filter silencer removed. It sounded almost like the stock mufflers at idle but had a strong and throaty tone at WOT. Never got pulled over on Woodward Ave for excessive noise/mufflers by the local LEO's. All the other Mustang's seemed to have Flowmaster or cheaper version mufflers. Too loud at WOT and excessive drone at cruising speed.

[@wtdonovan]

...maybe I missed it, he said the thrush was cheap and 3" but not what made it different? Looking online they appear to be "turbo" style mufflers with a perforated 2 pass and chambers at both ends. Seems like that was what made it drop power. I don't think cheap is the issue, you can get cheap straight through mufflers :) Thanks for posting this, it was fun!

[@notinterested5787]

Yep, comparing a straight thru magnaflow to a triple pass thrush turbo GUARANTEED that the high buck muffler would win. Sure didnt want to lose magnaflow advertising.

Try slapping a glass pack to reduce back pressure then no more than 24" straight pipe going into a dual chambered muffler off the glass pack and a over axle bend exhaust pipe to see if you get more or less torque an power when these parts are separately installed and or combined, when combined exhaust is quiet but doesnt make it lack power from my experience at least thats what it seemed. 2 into one exhaust hemi.

lol i have a flowmaster 10 series and i can tell you its alot lighter and sounds more like these other mufflers. the 30 series is almost like a stock truck muffler but you want a little more rumble. this 10 series flows alot better.
