Dumped or duals
 

I have a true dual flowmaster 40 series running out of the back, ive gotten alot of compliments on it, but i want to know if i should 1)dump it after the axle or 2)dump it and cut the cats. i want to get a little bit more of an intimidating sound, like a growl, but idk if the cats getting cut off will do the trick

dump it after the axle. don't gut the cats

ive heard that taking the cats off though increases horsepower?

it can, but the hemi likes a little bit of backpressure.

After the axle.. I had an AT3030XL dumped after the rear axle and it sounded amazing

Duals. I've personally never liked the way anything dumped sounds.

Agreed. Duals back, x pipe before mufflers to even out air flow, duals out. With 12 inch or 15 inch echo tips. Do that with two super 44 flow master mufflers. The outcome is a deep, menacing sound

I'm running dual 3 inch into cherry bomb xtreme single in single out, mine dump before the axel, I move alot more air than a hemi but its got a real nice rumble down low, and screams up high. No cats either.

if you dump it and not use echo tips you get a deeper sound only drawback to dumping it is more reverb in the cab i personally don't like how tailpipe exhuasts have more of a echo'y sound

Well if your wanting horsepower lose the flow master for starters and get a straight thru muffler like a magma flow.. I personally don't like tips out the back besides on lofted trucks with like 6 inch diesel tip. But each to his own. I'm putting a roll pan on in future to elimanate my tips

I used to have duals running out the back, but I cut them back after I put on the roll pan. They're now dumped over the axle and sound pretty good, it screams in the higher rpms. But I still want it louder lol

if you have true duals already, keep the cats and dump by axle...IF you want more deep sound.

i agree with you fastnnuffrt. im not sure what i was thinkin about going with flowmaster when i had it done. it was over 2 years ago, magna flow has always sounded good also

dump right before the rear axle and you will have a loud ass truck lmao, you should here mine, my brother lives about three blocks up the roar from me and he can be in his house and hear my truck when i start it up lol

you know my neighbors have to love when i come in late. if i start it and go in the house theres things in my house that kind ove viberate from the rumble of it idleing lol

I have mine dumped out below the back edge of the cab right behind the muffler for better ground clearance (tore off my duals in Disney on some rocks) and the drone inside the cab gets REALLY REALLY annoying over a long drive. I suggest you try and dump it out as far back as possible!

I've out grown the drone as well. Besides, why own a kickass stereo and have the drone frequency cancel out your sub woofers?
What really stopped me from doing it was losing a good friend from carbon monoxide poisioning. He thought his dumps sounded great....but he was dead wrong. :(

I would definitely lose the Flowmaster IF you can and keep the cats. I made the mistake of removing them on my '04 and it killed my 0-60.

so take out the muffler in all and run straight with cats

im wantin to change my exhaust also. mins is dumped at the rear axle.
im thinking of dual HD 50 series flows?

Say no to flow

I cant believe everyione dislikes Flowmaster, to me, there's a reason they are the most popular aftermarket mufflers there are...if you want rust proof, they have stainless.
I just ordered the catback Flowmaster kit for mine, should be here in a week.
I don't belive in the 'flow' other muffler manufactures put out, sometimes backpressure is good, and needed. Almost all the drag racers I know use Bullets, Flowmasters or Borla XR-1

I think it varies by engine. Flowmaster is the best sounding on my V10 IMO, but I love the Magnaflow on my V8 360.

We should open a section with video/audio of exhausts. I would post both of mine. Nothing like being able to hear your exact motor with different mufflers/setups.

Ill see if i can post a video tonight of my exhaust and yall hear what im working with

ill shoot a video or my rams exhaust, might have to put a warning lable on the loudness lol

It seems to be a ram thing on the few ram forums I'm on they all hate flow master and the forum boner seems to be magnaflow... I like both I just prefer the flow master sound and on a 3 ton truck a couple hp either way cannot be felt

If anyone can feel any seat of the pants on a 6000 lb truck 1-5hp, they're more man than me. Now if it's sound difference, that's a totally different thing. Personal preference. :D

I'm all about lettin a engine breath straight through. Best sound and its the cheapest. But I were goin for perfornance cherry bomb, all the way or chambered or straight through.

straight pipes on a gas truck sound terrible imo lol

I love the way flow master sounds on most. But when your trying get every bit of power 5-10 hp is more than you had. I live on the track and I don't know of any guys running chambered. But each to his own

Welp speakin of dumped exhaust, I guess mine is broke completely in half underneath the passenger floor board. But it's weird cuz no soot comes out right there and it didn't seem to sound any different.

^^^ I am witness to this. Never seen it happen like this before?

Ill say that the 8.0 sounds shitty straight piped, but my old 89 has a 318, that thing sounds like a total hard ass.

well I'm 44 years old, been to the track since I was 14...and going to Tulsa tonight, how many pics of cars with flowmaster do you want me to post tomorrow? :D
You've honestly never heard a Flowmaster at the race track??

Lmao

i like the way dumpd exaust sounds but its alot louder in the cab.....i like it that way i have that stack on my truck and my wife hates it i told her to get out if you dont like it lol same goes for anyone else if yall wana sound mean and rumble and really piss off the neibors get a CUMMINS nothing quiet about them.....also leave the cats alone it will throw off your fueling i will explane how it works if yall want.....jarrod you need a stack il come let you ride in mine later today if u want i love it
