Flowmaster Delta Flow 50 series?

[PHOENIX]

My choices for muffler are either:
Flowmaster Delta Flow 50 series
Flowmaster Delta Flow 70 series
Hooker Headers Aero Chamber

No matter which I pick its going to be 3" in and 3" out (one pipe all the way).

I emailed Hooker to see if the internals will burn up if too close to the cat like talked about before. If they dont, then its Aero Chamber for sure. Alot of you guys seem to like them and they are $25 cheaper then any of the flows I want.

But if the aero chambers will burn up (like Im thinking they will), then it will either be 50 or 70 series delta flows. What do you guys have to say about either of those? I dont want a lot of noise in the cab, and I want a deep, not loud sound, thats why I have choose 50 or 70 series. Just wanted to hear your opinions on the 2 flows.

Thanks.

70 or 50 series with dual exhaust is the way to go. If your going to spend the money get duals and get rid of the cad convert. If the shop wont get rid of it find one that will.

One pipe all the way? Are you sure you want to do that? Spend more now and save more later. You know you want to have duals so definitely save your money and get it done right. Misery loves company so join all of us with maxed out credit cards

[PHOENIX]

No I for sure want (1) 3" pipe as discussed before in another thread. I have to have a cat in order to pass emissions here in the greater Phoenix area. Without a cat I will fail no doubt. I dont want duals for a number of reasons, money just happens to be one of the bigger reasons.

Have ya considered Edelbrock or Magnaflows? They are a bit pricy, but they are shiny 304 Stainless Steel and should not rust, like it ever rains in Phoenix.

The Aerochambers won't burn up any easier that slowmasters will. They are a welded muffler too.

I vote for the Aero's.

[LOHRTBT]

Why would you think the Flows will hold up better than the Aeros???
Flowmasters are known for wearing out quickly and baffles breaking loose inside of them

[Tom]

Ive NEVER heard of a flow breaking or wareing out. Of course this dosent mean it hasnet happened

Id go 50 series. The delta flows are supposed to be quieter then the normal series, and the 50's are quieter then the 40's. I have normal 40 series on my 79. Remember how loud it was? Not very with those catco cats in front of em.

[LOHRTBT]

I have had one do it and several friends that have...but anyhow..the way I see it. THey will both eventually rust or wear out....they are not stainless. So why spend more when you get killer sound and NO resonance with hte Aero's. Trust me...They get pretty damn healthy sounding with some time.
Ask Prerunner.

I sure can tell you guys are young. I've never heard a slowmaster that wasn't loud. All they are good for is to make noise, which they do real well. Sounds like two cats fighting with guns inside a tin can to me.

You do know that Flowmasters are the worst flowing performance muffler on the market, right? This is a fact.

Sounds like two cats fighting with guns inside a tin can

Damn its about time, Ive been waiting for a muffler like this my whole life!

Ok now that, thats out of the way I think everyone needs to calm down.... j/k

The only reason I thought the flowmasters would work and the aero chambers not, is because I read on a site about the construction of the aero chamber. I was under the impression that there is something inside that can be damaged from heat easily (trying to find site now). Anyway I emailed Holley about it and waiting on the responce. So you guys say I can put this aero chamber muffler within a foot of the cat?

[swervin ervin]

Personally, I don't think any muffler will live long at a foot from the cat. Then things put off some big time heat. Move it on back to at least 3 feet and you should be OK.

i would got with the hookers. i'm gonna replace my flows with them when i get my shortie headers.

when i first heard dave's a year ago, they were SO quite, but the last time i was there and heard them(in november i think) they sounded great.

[LOHRTBT]

They are much louder now....still with no resonance

that is good

[TX_Mudder]

I have 2.5" duals with Flowmaster 50's.
In my opinion, the 50's are too loud. I wish there were not as loud.

I really would have preferred the 70s. Too late now.

Well I still have not heard back from the email I sent. I hope I hear something from them soon. What is the major difference in design from the flowmaster to the aero chamber (as far as inside construction)?

[79BIG10]

Eddie the Flowmasters have a baffled chamber inside like different compartments which give their sound and "slowness" since the gases have the flow harder through the passages. Aerochambers are able to go straight through with the passages and make a better sound, flow easier, and no tinny sound at all. I'm going with Aero's later. I love the sound of the Flows but Aero's are even better sounding.

[PHOENIX]

My choice is the Aero Chamber

Heres my question to Hooker Headers:
Due to the way I need to route this the muffler will only be 6" to 12" behind the catalytic converter.
Will the inside of this muffler burn up?

Here is their response:
There is nothing inside an Aerochamber muffler that can burn out. All the internals are made of stainless steel.
It should work fine in that application.
Thanks,

weld up 8 aerochambers to each cylinder!!

[swervin ervin]

Well, I think this answered that.

When you get the muffler, you will be amazed at how straight through it is. I still don't understand how they muffle sound. I do, understand how they flow so good though. I never could figure out why they call Flowmasters, Flowmasters, with the way they are built. How can it flow good having to go around all the baffles inside the case?

I think you've made the right choice.

[PHOENIX]

Hey Ocbaud that would still be cheaper then what im gonna do now Do you think I would need a cat for each cylinder too?

Mike I think I did too, alot of you guys who have flowmasters would rather have the aero chambers, plus you guys talk all this about flowmasters breaking. Plus these are cheaper, and look like they put some real time into designing this muffler. Flowmasters seem like they could easily be made in your garage.
