Ok heres the deal. I want to change up my exhaust. It kinda sounds like **** right now.

Right now I am running no catalytic converter, and a borla xr-14 muffler. Its raspy as hell, but it has a nice volume.

I want to get a very nice low growl sound but with maximum volume possible. I have decided I am going to run with a flow master exhaust and a high flow cat.

My problem is which flowmaster to go with to provide the best outcome that I want.

My top 3 choices were 40 Series, Super 44 Series, and the new Super 10 Series. Well I have decided against the super 10 because I feel that it will still be too raspy.

So now its down to the 40 Series and the Super 44 Series. From videos I have seen/heard, the 40 has the best deep rumble sound that I would like to have. But I just cannot tell volume levels from a recording.

What do you think?

My exhaust has the stock 2 cats and is just y-piped. I have a 4.6L. Link to my vid:

I would suggest 3" duals. And use the 40 series.

im stock cats y pipe. i loved it on my 5.7 camaro, perfect fit.

with my weak 4.7 i would like to get rid of the muffler for a little more loudness.

its kinda sad, most of the time i cant even hear the exhaust, luckily i didnt pay to get the exhaust done.

WTF most of you guys responded with non flowmaster responses when I said I was going with flowmaster. You wasted your time responding.

i ran flows on my 96 mustang 40 series...they were rotted out within 3 years....and there isn't any salt on the roads in louisiana...to me flows are overpriced tin can junk...so i went Borla for something that will last the lifetime of a vehicle

If you are set on flowmasters, then that will be your mistake. I even suggested the flowmaster that i think is the better sounding. Dynomax is better than flowmaster IMO. But regardless, do the biggest exhaust you can fit and afford. The bigger the pipes, the better.

I still have 2 cats. Took one off but don't want to go through the pain of taking the other 2 off.

x2

we didnt respond with flowmaster info because we dont run it and dont suggest it.

my dad took his truck up there, put flowmaster on it. the guy at the shop was like why?

my dad said, i heard its good man! guy says it will sound way better without any muffler.

so he started it up for my dad let him listen. a week or so later my dad goes back up there asks for them to take the muffler off, and it sounded way better...

now perhaps with the 4.7 being a weak/quieter motor, maybe it needs more help on being louder, but on larger engines it deff does not need it.

Thanks for the more detailed response. I need a muffler because straight sounds like straight up ****. It gets loud as hell without a muffler, but it doesn't sound very good at all. This is why I want to control the sound with a muffler.

Dont get me wrong I like the Borla I have now, it just isnt loud enough with the cat on. I just want a very deep sounding exhaust that will produce a decent volume at the same time.

From the videos I have heard on youtube, Flowmaster has the best deep sounding mufflers I can find.

Too Raspy...

It's really hard to get loud without being raspy. I've spent many hours in a muffler shop and have many redneck friends. Usually the louder, the more raspy it sounds.

Do you base your audio purchases off youtube as well ?

For what you are looking at, do the biggest size pipe you can and a Dynomax race bullet, if you do duals, obviously 2 dynomax race bullets. They are cheap, they do exactly what you want, and they last.

I am becoming convinced. And they are much cheaper too!

How loud would you describe them as being though? Its hard to tell from vids

I could take you a vid but it would be ****** and not at full tilt because my truck is running on 5 out of 8 cylinders. I have had people tell me they can hear me from half a mile, ive had people tell me it sounded like a race mustang, i got a ticket from a state cop here in Va because he heard me downshifting from about 600 yards away with his windows up. My truck is a stock 302 with 250K miles, 4.10's on 33"s. Exhaust is short tube headers, through 1 stock cat to a single 3" dynomax dumping right before the back tire on the passenger side.

In short, on my truck, ive been told its loud as balls.

guy at work just put on a gibson exhaust system on his dodge. sounds good when he first put it on and now it sounds wicked.

Every flowmaster i have had or have seen has rotted out pretty quickly. This dynomax has been on my truck for 7 years i believe. Truck has been flipped, been through mud, snow, salty/sandy roads and its still in great shape.

I dont really want to spend 400 bucks on the exhaust right now for new pipe and custom bends and the 2 mufflers and cats.

It wouldn't cost that much. Why don't you just y-pipe it? I bet it'd take some of the raspy-ness away.

So I have another question on the Dynomax Bullet. Which length? I am going to stick with stock pipe size, so I am running 2.5" pipe. There are 2 lengths available: 12" (16.5 Overall) and 18" (23.5 Overall). Which one would be better?

Thats going to be up to you. The shorter it is, the louder it will be. The longer it is, the deeper it will be. 6" wont make too much of a difference but the length thing works on glasspacks too where you can get an 8" or a 24" and all that. I have the 12".

Original flowmaster 40 series sound a lot better than the dynomax bullets. i have the flows on my chevelle and the bullets on my el camino. the dynomax doesnt sound bad at all, i just like the flowmasters better. just my two cents.

Yeah, I have listened to literally hundreds of clips determining what I like best. I agree the FM 40 has a great sound. But for me the Dynomax sounds the best and has the best volume, especially for the price!
