Louder? Magnapack. Deeper? Twister. The twisters and the Moroso Spiralflows are very similar and both have a deep, rumbly, very muscular sound, where as the magnapack isn't quite as defined, louder, and just nastier. In my opinion it sounds a little more midrangey and not as refined.

which will sound better in the end of my y pipe with cats ? i want it loud and deep and that flows good. And if it is not one of these mufflers which will you recommend?

Funny you ask because I have a Moroso Spiralflow running straight off my off-road y-pipe and the sound is....well.... . It sounds DEEP as hell, very rumbly and powerful and idle, and when you go WOT, it sounds very defined, not muddy at all, with VERY little to no rasp, even without cats.

camaro15

do you have a sound clip or pics ? do magnaflow flow more than twisters? and are the moroso spiral flow power robbers.

8banger

Not yet, but I might soon. Magnaflow flows a little more. I wouldn't call them power robbers. While they aren't as straight through as bullets, they still flow VERY well, it's not like a Flowmasrer 80-series on anything near that bad.

how do sweet thunder compare to these two muffler? do sweet thunder sound and flow better?

Sweet Thunders probably have the least flow of the three, but still aren't bad at all. In terms of sound, it is louder and clearer than the Spiralflow. It roars...not quite as deep as the Spiralflows, but a little bit more aggressive and 'mean' sounding. Haven't compared it to Magnapacks, but I'd imagine the Sweet Thunders would be better sounding, more defined, and not as raspy.

If I had a mustang id get the maganpacks, never heard em on an f-body, but do know theyre loud as ****.

yeah...how practical would it be to get one sweet thunder muffler, or one 'magnapack' bullet styled muffler installed after the y pipe merges and then getting custom piping fabbed up to go out the back? As in...how difficult would it be, which of the two would be louder/deeper?

8banger

iTrader: (16)

Yeah, loud, that's about it. IMO, 'normal' Magnaflows sound better.

As far as the muffler after the y-pipe, not a bad idea, basically what I did, except I dumped mine, but for that much money with all the custom fabbing, I'd rather buy a nice catback (GMMG, Corsa). Probably wouldn't be to difficult, but any time mandrel bending is involved, it's $$$. The two mufflers would be about the same in terms of volume, but the Sweet thunder would sound much deeper, much more defined, and not nearly as harsh.

will the sweet thunders flow good in the end of my y pipe? which of these three mufflers will have the most rasp and drone?

8banger

iTrader: (16)

They will flow well, maybe a LITTLE bit less than the Spiralflow. Most rasp and drone goes to Magnapacks...I am not a fan.

camaro15

have you heard of dynatech splitflow muffler ? how do they sound?

8banger

iTrader: (16)

I know nothing about it, honestly.

camaro15

Which muffler will be ground shaking and very deep with alot of rumble with no rasp and drone in the end of my ypipe with cats? will it be one of these mufflers or some other muffler?

8banger

iTrader: (16)

Moroso Spiralflow would be my vote.

camaro15

do twisters and moroso sound the same? are twisters quiter? which is deeper?

8banger

iTrader: (16)

Virtually identical. Just that Morosos are easier to find.

My friend runs one on his Latemodel stock car, his is 4" sounds good, doesn't muffle much, very deep, less harsh than bullet style mufflers. I would go for it.
