just like the title say, how would these two exhaust compare to each other in sound and in flow? they are both 3in/3out... I need a answer today! thank you!

they both will be ran with long tube headman headers, and no cat

is one going to be more:
rhaspy?
deeper?
louder?
flow more?

ANSWERS PLEASE!

they probably flow about the same. i'd imagine that the round muffler will be louder, but possibly raspy depending on the mods to the engine. i know you'd be very happy with the oval muffler. a buddy of mine has one and it sounds amazing. very mellow at idle, but boy oh boy does it let you know it's there when he mats the loud pedal!

 

you know that is what i was leaning to all this time, its just that a just got a unbelievable deal on the round one, and i didn't know how it would compare to each other..

the guy said it should sound similar...

my engine is a 383 stroker, 6.3L, my cam is duration is 214 int./224 exh. @ 50 my lift on that cam is 0.442 int./0.465 exh. lift with 112

my headman long tubes have 3" collectors, going to a 3" wye pipe, into a single 3" main pipe, NO cat, and need a muffler bad...

this is the last piece of the puzzle..


I love deep notes, I hate rahspy, I want it to be loud when i stomp on her good... but I would like it to be little quite @ idle, sorta like a lil sleeper, till I open her up... I travel with my windows up most of the time...

 

common guys..

i just spoke with him on the phone, and he just sent me a link to this video. he said this is the closest thing he can find that sounded like his round magnaflow...

but minded this clip is with cat converter and stock headers...

no idea what longtubes, no cat, and my bigger 6.3L with my cam lift and duration gonna sound like...

 

with your motor any muffler will sound nice. Hey, if its cheap give it a try. Magnaflows have a real nice sound.

 

haha, so tempting, damn it you are correct... lol

i just hate rhaspy you know what im saying? like pop pop pop pop... i hate that... and i didnt know... but being since that muffler is kinda long, it should eliminate that too..

he wants 45 shipped!


if anyone has any idea, or heard either please chime in as well...

but you make such a good point!

 

well the exhaust "pops" are due to air being sucked back into the exhaust system, and is usually caused by restrictive exhaust manifolds. You shouldn't get that with LT's and any kind of muffler.

The round one will be louder and a little raspier, but depending on your RPM's at cruising speeds drone should be minimal with both setups.

My recommendation would be a hooker Aerochamber muffler and a cutout for the track. Aerochambers sound great on LS1's with LT's and no cats.

 

cool, well im glad it wouldn't be raspy... yea, well im getting the round one.. thanks.. i heard of aerochambers b4, but i was set on getting a magnaflow for the deep sound, and if not I wanted a Corsa muffler for the 6.0 either touring or sport... but i think ill be happy with this round magnaflow...

thanks for the response...

from what my good budy told me, the round one would flow slightly less... 550 cfm vs the bigger one, which is why its considered performance, it flows at 625-640 cfm... which isnt a bad difference.. as far as performance...

the stock flows at 250 cfm... so ill be very happy...

 

thanks again guys.. got it in 3 days..

I am extremely happy, I thought it was going to be thin, and tiny.. but its big round, long and heavy... just by looks, I know ill love it!

 

Damn, that thing looks brand new! Just out of curiosity, where are you planning on putting it on one of these cars?

 

yea it does, he said it had 300 miles on it.. and judging from the inside, I believe its less! its virtually NEW... for half price. I plan on putting it into my burban...

its a picture on page 7... of my build up. page 8 & 9 talks about exhaust as well, as headers and 02 sensor placement... you can read the entire thread from the beginning.. but its very long...

hey I also got alot of questioned answered from Magnaflow.. its NO difference between the round and oval mufflers... They are different as for sizing reasons.. So im sure it will be nice and deep and sound great! I was told even this 24" case makes it rumble nice and low...

here is the FAQ:

http://www.magnaflow.com/07techtips/faq.asp

 

well if any of you in this section was following, you can click my link to my thread posted above.. but here is the video of my new exhaust..

 

Is that smoke or rain clouds comming out of your tail pipe?

 

its called condensation... for every 1 gallon of gas you burn, it produces 1 gallon of water... its about 50-55* in that video, you can see your breathe.. my truck runs with a 160* tstat, its tunned that way... my exhaust is so free flowing, and not restrictive like stock, more condensation come out.. even after its off, it will still condensate as the pipes are hot still, and try to evaporate the moisture..


----------
on another note, i was also told new exhaust does that, because of the new welds, pipes, and headers... and it should calm down just a little bit in a few days....

 

I was just razzin ya...but for real that is alot of condensation, sounds good though!
