Need help deceiding on MagnaFlow or Flowmaster!

[97GT]

Hey all I've searched for information to find out which exhaust is better for me. I have heard flowmasters have a better sound, deeper growl than magnaflows, but mags perform and flow better. So its 50-50 right now for me. Right now I believe I have dual in dual out 2.25 pipes with a 50 series muffler. I really want to put true duals but I dint want to deal with changing things back and forth when I get it smogged. So what application should I go with? Im looking for a deep rich sound with a good growl when I step on it. should I change the pipe size? any info will help. Thnx all

im a magnaflow man. Its all up to you tho. We get these posts every day whos better.. Best thing to do is check out youtube tho and just search chevy vortec flowmaster or magnaflow.. theres sooo many videos up..

As to pipe size, 2 1/4 is plenty for now until you get going with engine mods. But i dont think stepping it to 2 1/2 right now is worth the hassle.

Even check out magnaflow and flowmasters website, they have clips on there as well..

another thing, if you want more sound, buy a set of longtubes and do the whole thing front to back the right way

thnx for info

Sounds good. So how much different of a sound do magnas give off when compared to flows? I've had flows on a few different vehicles cause they sound great. Just been thinking about trying something different. I have tried to watch a few videos but its hard to tell cause they dont do the mufflers justice. I was thinking bout some headers who should I look at?

 

[AtomicHoe094]

ive only owned one flowmaster and that was on a ls1, too quiet for me tho

headers--- ******, pacesetter, the usual name brand stuff is fine. id recommend Ceramic coating tho.

Im doing a custom 3 inch exhaust. long tubes, 3 inch pipes, and a flowmaster 50 series delta flow, and a single tip in stock location. I have dual exhaust setup right now. I had a 14 inch magnaflow with an internal x pipe. IT WAS LOUD! The interior resonance was awful! i recently put on a flowmaster 50 series suv on it. it sounds GREAT compared to the magnaflow. I LOVE IT! and to be quite honest you cant really tell the difference in performance... I mean sure you might be able to if you had a a high performance engine and stuff like that.

 

[97GT]

so what magnas do u have and are they louder than lets say 40 series flows thats what im looking at. Also i'm looking at doing a motor swap in the near future, either 383s or ls1, cant deceide the best route

i want more growl so not worried bout how loud it gets, just dont want it over the top annoying. Do hi flows cats do anything?

I have Magnaflow and love it.

it is the 5x8x14 magnaflow dual 2 1/2 in and single 3" out with 3" pipe ran from the muffler to the tip and it is a 4" tip 12" long

I have true dual 40 series flows on my hoe and I love them. They are very loud and have a nice deep note that rips what you punch it. I personally dont have any resonance issues but I have read a lot of people that do. I will also say that my friend has magnaflow on his dodge ram and that thing sounds sick as hell also.

You can get different grades of both Magnaflows and Flowmasters so when comparing make sure you're comparing two of the like "grades". I've had Flowmasters for years and just recently went with a Magnaflow for the first time on the wife's burb. I like the sound of both to be honest with you. My '77 has 2 40 series flowmasters on it (and I've had 40 series on 3 other trucks in the past) and just LOVE the rumble and tone that comes with it. With that said, be prepared to have "drone" throughout the cabin of the vehicle. Personally, I like that and it's just part of it but some people don't. You'll run into the same thing with a loud enough Magnaflow, though.

I've only had 1 magnaflow muffler in my experience
blizzardx23 had a flowmaster (don't know which series)

what I have come up with is magnaflow will amplify the sound of your engine therefore making it subtle at idle and have a nice sound on wot

flowmaster is one to shape the sound.
so in essence depending on the series it is making it louder or lower and shaping the sound

just my .02 I would go with magnaflow personally

So 07 burb how are u liking the magna on the burb. Im looking into getting one but I dont want it loud. My job is 55 miles one way and I dont think I will like it very much. I just want it to sound a little better than stock

As of now I just have the magnaflow with the resonator still there. We just took it on a 1000 mile round trip and it was great. You could hear it when you got on it but was fairly quiet while cruising down the highway. Tonight I'm taking off the resonator and putting SLP tips in it's place. I expectit to sound even better

 

[19Yukon97]

I have a 14 inch case length magnaflow muffler. dual in dual out. cant remember alll about it... personally i like my flowmaster so much better! like im in love with my flowmaster and i honestly think i will ever buy a magnaflow ever agian. My magnaflow had a really bad interior resonance. my flow doesnt have as bad. it was quite at idle but when you got on it or stood around 2000rpm it was loud as hell! Personally i think that it might be the same loudness as a single super 40. not true duals.

 

[97GT]

Thnx for the opinions guys it's helps on making a decision. I will probably stick with flows and go with 40 series. But should I go with true duals or stay with a single muffler two in two out?

 

[19Yukon97]

I have a dual in dual out 50 series on mine. i was going to do true duals... but i changed my mind and me and my dad are going to build a motor forthe yukon and then im going to build a 3 inch exhaust from the collectors of some longtube headers. prolly going to go with alittle louder 50 series delta flow muffler. its going to be a single out the side like stock position, with a 4 or 5 inch tip. hope it sounds mean!

I think a single 4" is perfect that is what i have

 

[sopethree]

i just had the new magnaflow strait thru's put on my truck. true duals. it sounds amazing. i also got black chrome exhaust tips. i had never seen them before, they look awsome and sound even better.

 

[07Burb]

got pics of the black chrome tips?

 

[raptorforme93]

Yea pics!!! I bet they look sweet...

 

[felixgun]

I've had flowmaster dumped/turned down on my nbs and Magnaflow with resonator delete/tips on my nnbs.

Magnaflow FTW.
