New Magnaflow exhaust clip

[85_SS_302_Coupe]

Well, they are among the best performing mufflers, but there are plenty others with similar "gains".


This is from December 2002 5.0 Mustang mag, Muffler Dyno Shootout. They dyno test 15 mufflers on Rick Anderson's coupe. They didn't do a stock baseline since i don't think the car ever had stock exhaust, but they did do open exhaust with no mufflers.


Open - 365.2hp/330.1tq
Bassani Street - 372.0hp/330.1tq
Bassani Real Street - 373.7hp/333.8tq
Borla XS - 373.3hp/332.6tq
Borla XR1 - 370.0hp/334.0tq
Dynomax Ultra Flo - 369.4hp/333.2tq
Edelbrock Performer RPM - 370hp/331.3tq
Flowmaster - 369.4hp/331.8tq
Flowtech Afterburner - 372.3hp/330.1tq
Flowtech Terminator - 369.5hp/331.3tq
Flowtech Warlock - 366.3hp/325.3tq
Flowtech Warlock *opened* - 374.2hp/333.1tq
Hooker Aerochamber - 372.1hp/330.4tq
Hooker Maxflow - 373.5hp/333.0tq
MAC - 372.3hp/331.5tq
Magnaflow - 372.8hp/332.5tq
SpinTech - 371.6hp/332.2tq

So the Magnaflows fall into the upper HP/TQ range out of the ones they tested but they also fall on the lower end of the decibel reading out of all tested. I'm not gonna type out all the averages but they were among the highest average hp/tq throughout 4,700rpm-6,600rpm. The point is that unless you're shooting for some kind of peak hp record where very pony counts, you really can't go wrong with just picking what you like the sound of the best.

They aren't very loud compared to other brands until you start to build up your engine. My car with an HCI and magnaflows at idle is damn near as loud as magnaflows on a stock engine being reved.

You'll like the sound much better with tail pipes. I ran mine without tail pipes for a month and IMO they sound 10000x better with tails.

Here is mine. My car has better flowing heads on it now, so at this point it may even be louder than this video, but its still the same basic sound.

One more from inside the car with the same mods as my last video above. The crunching sound is the camera on some paper.
