It seems as if their saying MAC is the loudest muffler. Now my question is Mac has different muffler does anyone know which ones they are talking about?

 

[fiveoho]

is it Mac Flowpaths?

 

[NoSloCoupes]

They were the new(at the time) stainless steel polished flowpaths. They weren't the loudest tho, keep in mind these readings were in a metal dyno building....don't know if it matters any. Click the link in my sig for the article.

[savegoodautonfg]

I wanna know what the loudest muffler is?

 

[88gt]

I'm rather proud of my cheap 'ol Flowtech Afterburners!!


Thanks for the info..

 

[Green93Hatch]

I know this isn't exactly what you were asking but I have MAC pro-chambers on my car with long-tubes and it has an awesome sound. I hadn't even heard what they sounded like outside of the car until yesterday when i let my cuz drive the car. Gives a nice deep, aggressive sound and it's pretty loud, but i have heard louder. I was honestly surprised at how good it really sounded, cause i am used to hearing it from inside the car only.

 

[NoSloCoupes]

Look at the readings, some maxed out it.

I ended up running the bassani street(quiet thunders) after the test...nice rumble at idle and screamed at wot! No ****ing drone either like the numerous set of flowmasters i've ran. I recently picked up another set of bassani's for the new coupe also, kickass sound! Got em really cheap off ebay,(they are stainless, not the aluminized).... less than a set of flowmasters,lol.

I tried the bassani race(real streets) out for about 2 days, those mother f'rs were LOUD! Too loud for me, and i love to make noise!

 

[92importkiller]

i have mac stainless pros on my car and it sounds great, a buddy of mine has 30 series flows and mine is louder at idle for sure but they are about equal at high rpms.....but i like the sound of the mac's waaay better, it has a nice raspy throaty sound, not quite as deep as the flows though........you can hear me comin from a long ways away

 

[89white50]

if you read they used a flowmaster from an SUV spec one. Its not the same aswe run, they couldnt get one in time so they just used that. I bet you the original 40 series is louder and makes more power than the one they used.

 

[NoSloCoupes]

No, thats what i original ran...the 40 series flowmasters. Believe it or not, my baseline the day before with the 40 series...368rwhp. Don't pay to much attention to the power #'s...i know, sounds weird huh. If they all came within that close of each other, pick what sounds the best to you...or go by price. Thats what i did, chose what sounded kick ass to me....and i could have had any set i wanted.

[68torinogt]

this is good info

 

[NoSloCoupes]

I can't believe its going on 4 years now since we've done this test! Did it in may/june of 02....took 6 months to make the mag,lol.

 

[68torinogt]

maybe its time for a new one b/c it is very useful and now there are more types like slp and many others

Dynomax race bullets are the loudest muffler you can get.

 

[savegoodautonfg]

Hey all,

I heard One Chamber Flowmaster Race Mufflers are one of the loudest, if not THE LOUDEST.

Look what i found while i was searching for them..
