I've got Magaflows on my Duster (got water vapor rust holes in them, getting bad. Been on a long time!). I'm thinking of going back to Flowmasters. I fairly sure the Magaflows will out flow the Flowmasters. But does anyone know by how much. I'm no longer racing it, so it's just a sound thing now.
Thanks

Not MagnaFlows, but a friend had a set of Flowmasters behind his 10 second E-body 440. He dynoed with those on the car. Cut off the Flowmasters and installed DynoMax Ultra Flows. Pulled 20+ HP more with the DynoMax mufflers.
I have UltraFlows behind my 340 and they are MUCH louder than the DynoMax Super Turbos they replaced.

If it's a sound thing now, Flowmaster it is for me. I don't like the drone driving it, but I know it sounds good outside. I LIKE the sound of Flowmasters.

"I'm no longer racing it, so it's just a sound thing now."

Balderdash.

Don't do it...... Flowmasters are junk. You'll sound like every 5.0 Rustang shaking parts loose on the streets. Want something unique with a great sound? Classic Chambered Powersticks. Look for the thread on mandrel exhaust and listen to my cars sound clip.


Here's the clip....

DynoMax here too. Luv them Flowmaster

goerlich xlerator. I get a lot of compliments on how my car sounds 2.5" x pipe with 14" body.

Magnaflow 3 inch X pipe system in mine.
If you watch the /Drive or /Drive+ video you can hear what it sounds like

No flowmasters for me (an ironic name for them!); I'd rather have a muffler that doesn't choke off performance so I'll stick with my Ultraflows.

Flowmasters sound cool... this is clearly evident because EVERY car 'with a pair' driving by has 'em. They dont flow well though... almost every real HP muffler out there kills 'em on power, some by a lot.

Personally, i've never been a fan ov Magnaflows sound. Nice mufflers, good quality, very nice power (some say the best), but yeah... i gotta be in love with the sound so... no.

Spintech or Borla... sound AND performance. Spintechs have a sound that not everyone will like, but my Charger's tone never got a single bad review. Personally... for my cars i'd take either ov these. Had Spintechs on the Charger and on the 96GT Mustang, both with a Dr. Gas X-pipe. Glorious. The current GT will likely get Borlas... just to see if i like it better.

I've got a set of Flowtech Raptors on my Dart. 2.5 inch exhaust. Not sure on flow, but they sound awesome!

Have you looked at the Dynomax Ultra FLows, Hooker Aerochambers, or the Hooker Max Flows?

I have run back to back runs (same day an hour apart)on the Demon switching from Flowmasters to Magnaflow, I saw no difference in ET or MPH on my car. The Magnaflows are a bit quieter. 3" TTI exhaust with x pipe ending at the rear axle. 40 series flowmaster and Magnaflow ultra.

I ran the early crimped steel Magnaflow 14x3 center outlet and offset inlets on my Duster mounted behind the rear end between the sub frames and 1/4 panels. They sounded decent in the car at part throttle cruise and weren't horrily loud at WOT, most peole said they really like the sounds of them when driving it on the street or at the track At the local 1/8 mile track removing the complete exhaust system pick the car .03 ET and .2 MPH, not worth doing IMO Has anyone on here ran the longer stainless steel Magnaflows 18 or 24 inch long straight (not the three chamber ones) through muffs yet?If so how did you like them. I'm putting a 1966 Dodge Coronet Deluxe together with a 440 motor and Hooker headers with Summits 3 inch pipe kit without muffs, any comments on those muffs appreciated

Come on now...You know what I meant.
Poppycock.
Horsefeathers.
Bullcrap.
Not racing? Who decides to stop racing when it is still so much fun?
