Hmm, well both a 40 series and 80 series are going to be loud. The big difference between the two is the 80 series is going to be alot louder inside the car.


Also the 80 series has dual outlets, where the 40 series has a single exit.

 

Yeah, flowmaster's new model, called a Hooker cat-back

sound clip in sig.

 

Thats an option too. But if you want Flowmaster and you don't care if you have dual outlets or not maybe the Delta Flow 40 Series or maybe a 50 Series. If you want dual outlets the only choice is the 80 Series but it will be loud, don't know whether it would be for some1 not looking for loud.

 

I want it to sound deep but not loud, but above all with performance in mind.

Well if that's the case, I would look away from Flowmaster. Also, a lot of people around here say those aftermarket chips are nothing but a waste of money. -89IRO

 

LM cAc cOc , cWc cTc cFc are you talking about

 

HITHEREHITHEREHITHEREHITHERE, let's talk like HITHERE human, what does all that mean?

 

Holly HITHEREHITHEREHITHEREHITHERE, this thing is really screwed up

 

lol , it was all an April Fools joke.

 

..

 

if you want sound, then go with the slowmaster. if you want performance steer clear of flowmaster IMO. Go with a magnaflow or banks setup...they have the straight thru muffler design, all stainless steel, and also have a nice sound like a big block MOPAR engine.

 

DYNOMAX!!!!!!! :rockon:

Quiet at idle, louder under acceleration, loud at WOT, and flow more than "Flow"master.

What more could you want?

Oh...... did I mention it's about 1/2 the price of Flowmaster?

 

your brother is right. it would require a lot to obtain true duals.

actually it would give you the worst performance of the flowmaster models. however, if youre wanting dual exits, it is the only way to go without making things complicated.

flowmaster catbacks are completely bolt-on, and come with all the necessary components.

i would recommend the flowmaster force II catback if you dont mind only having one exit. however, if you want the dual exits, the flowmaster american thunder catback is what you want.

 

Magnaflow and dynomax are nice IMO, but if you want all out performance, and a unique sound, and not to mention the best quality (I've compared them) then go with Spintech. You will pay like $20-$30 more for spintech than most (not including borla), but you also get a lot back in return. -89IRO

 

If you go with Flowmaster, you can purchase the dynomax 3" mandrel bent exhaust tubing with twin tail pipes all seperate. Add the 3 " in and dual 3" out Flowmaster with the exhaust tips of your choice and have a sweet azz exhaust system and save a few bucks doing it. Or add the muffler you finally decide on. I have the Flowmaster on my system and I am not disapointed.

 

Yeah, a lot of people like flowmaster because it sounds good. Nothing at all wrong with that. Others, like me, don't really care for the drone. I prefer the cleaner, crisper, tone better myself. My buddy has dual flow on his camaro and you can't even hear yourself think inside of it. -89IRO

 

how come every1 says the 80 series is so loud? I have the 80 series with edel headers, it still has the stock I pipe but I have a cutout for all out performance, but with the cutout capped, my car seems extremely quiet still. It sounds good, but unless Im at wot you can't really even hear the exhaust inside the car, if the cutout is open then it sounds umm well loud.

 

I have the 3" catback with a 3" in 2.5" out 80 series, and its very loud inside. But im happy, because thats the way I like it

 

well, like you said you have the stock i-pipe and a cat i assume. it makes all the difference.

 

For the absolute loudest sound you need 3" mandrel bent exhaust, good y-pipe, high-flow converter, a muffler that is made to be loud, (80 or 40 Series) and some power behind it. (a 350 at least if you don't plan on modding much)

 

hmm..i have a 350, i have headers, with a 3" y pipe, no cat, stock i pipe and flowmaster 80 muffler, I figured that the stock I pipe was to blame but I figured it would still be louder than it is, oh well thats why I leave the cutout open most of the time

 

Yup headers (you have them) and better I pipe help too. Engine mods will help too. I don't know what kinda loud you are looking for through an exhaust system LOL. Your setup should be loud, I don't know what your definition of that is though.

 

I have T.E.S. chrome headers, a 3" carsound high flow cat and all the other stuff listed below and it's not all that loud. I doubt I'd get a ticket. I've taken off from a stop a few times next to a cop without any problems. But than again, noise is an easy excuse to be pulled over for.

You say that for an exaple flowmaster 80series dont flow as good as hooker but how much of a difference is there in hp on a almost stock 350? 1hp? i think that when you got a engine that makes some serious hp, then maybe....... or what do you think?

 

that is all you need to stear clear of flowmaster. i wouldnt get a chip either, not for these cars.... and not unless its custom...

 

you run a converter, that's why it is quiet. and noise can be a reason for a cop to pull you over (in my experiences). but mainly a catalytic converter equipped car will not be very loud.

 

I read this thread yesterday, then listened very carefully to mine as I drove home last night. I know Flows have a reputation for being "tinny", but maybe I've just gotten used to it and don't hear it anymore.

It isn't "quiet", but it isn't excessively noisy, either. Certainly quieter than the '57 (and the Warlocks DO sound tinny). I do wonder if I'm disturbing the neighbors when I leave in the morning, but I certainly don't try to.

I haven't seen any back-to-back dyno or strip testing of muffler, certainly not 3rd gen related. Flow bench may not tell the whole story, either, because exhaust isn't a continuous flow like a flow bench is. So, a muffler that flows more on the bench may not produce more power than one that flows less on the bench.

I would agree that the total system is important. I do have a cat, and mandrel-bent 3" pipes. I chose the dual-opposite Flow because I liked the look better than single 3" or dual side-by-side. I figured the 305 wasn't going to overwhelm it, anyway.

I don't know how much the Dynomax pipes would cost you, but I got the Pacesetter cat-back from JC Whitney, and Flow from Summit. It's not perfect (I screwed up and got a universal cat instead of a direct-fit), but it hasn't given me any trouble.

 

yeah, youre right. maybe more than 1 hp, but definitely not enough to be able to tell the difference.

 

Yup.

 

The amount of horsepower that is involved between most good mufflers is not even the equivilent in what the horsepower difference is that 2 identical motors produce.

you run a converter, that's why it is quiet.

Yes, If you want to pass smog in California than make it look like it is 100% smog legal. Have all your paper work lined up. ARB stickers in place and then make it pretty. I left the cat on it and I do like the sound. I have yet to run my car since I went to the 5.7.. Still wanting some other mods too but I got to see what it does like it sits now

 

I can tell you from experience that it cost me 7HP on a stock 305. As long as HP is not a concern flowmaster would work.

 

Can't beat a cutout as far as performance goes.
