How much diffrent in interior noise between flowmaster three
chamber system (Force II) compared to Corsa?
I am aware there is no resonance with the Corsa and unsure if I
should spend the extra money for it. All I am really concerned
with is interior noise and resonance. The sound of the exhaust
outside the car will be okay either way to me. Nobody around
here I have found with the Force II flowmaster.


Thanks for the opinions.

 

I have Flowmasters on mine and I don't find the interior noise all that bad; in fact I find it just about right and love the sound both inside and outside the car. Other's will say it's a little too loud for them. Personally, I've heard the Corsas on C4s & C5s and don't care for their sound -- just my opinion, other's love them. My advice is to try and find Vettes with both and listen to them, inside & out and make your decision. If you can't, see if someone could post sound clips. I would, but mine would be a little misleading, the turbos give it a whole different sound.

 

If you keep your foot to the floor, you'll never worry about resonance again.

I actually like it, it helps to soothe the soul on a long drive.

 

MagnaFlows here. If you want to hear them,call me and I'
ll put the phone in the car so you can hear it.

 

The flowmasters are going to give you a headache...Natham has a post somewhere on the tech boards with a Viedo he has flowmaster.....I think his post title is like "LT4hot cam in F minor" download the video and you will see how loud they are...

I have the Corsa's they give the car a very nice look and sound great, and is truely a high quality product

 

I went with the Flowmaster Super 40's. They sound great outside the car, and are fairly quiet inside the car, best of both worlds. They already have a black case so they look stock from behind, no silver showing. Much less expensive too.

 

Yeah what he said... personally I prefer the Corsa. I think that any and every car with Flowmasters sounds the same, it sounds good... but still the same. I put Hooker AeroChambers on my car and I really like them. I think I'm going to swap in some Ravin' mufflers though just to see how they sound

 

Understand that I have the flowmaster 40 series mufflers which is a dramatic difference from the Force II system. The Force II is supposed to be much quieter.

 

I hope it sounds good because I am about to order the force II system from performance peddler. Cat back is $600.00 shipped, (make sure you type, "peddler" in the discount box, top left corner). Includes resonater, pipes, and 50 series delta flows. I have always had good luck with Flowmasters and even have them on my '96 Taurus SHO.

 

I know I didn't buy a vette to be quiet I have flow Masters and I love the rumble when I pull up to the stop light. Now when I open my electronic dumps, Thats loud!

 

Judging by Nathan's video, my Force II (50 series) system is MUCH more tame. The sound is similar just a whole lot more quiet. The rest of my setup is Hooker LTs and no cat.

I have never heard a Corsa in person so I cannot comment but I love the sound of my Flows.

EDIT: BTW my system has little to no resonance. I have no problem driving the car for 800 mile cruises every so often.

 

 

Corsa with cats

Flowmaster Super 40 (no cats)

Is it just me or are the Corsa's actually louder at RPM than the Flows (which was a 3" no cat system) A personal observation...as the engine got bigger the flows got louder inside (my first 85 had flows and were the same loudness outside w/ stock motor), but the corsa (as compared to those with 350's) got louder outside.

 

The corsa's may be louder, but actual volume may not be everything. If you just want it to be loud you can run open headers, but in my personal opinion that sounds like crap. "Loud" isn't good. Think of it this way, if you like to listen to heavy metal and do so very loud, does country music sound good just because it too is loud? Don't think so.

I've driven two cars with Corsa exhaust. One was a C4 with EM headers / cats. The car was as quiet if not more quiet at cruise than stock. Outside the car it was louder than stock but not drastically so.

The second car I've driven with Corsa was a C5, fed by kooks headers and no cats. With the cam in that car it sounded exactly like a tractor from the outside. Inside the car was the most ear splitting high pitched wail you have ever heard. I thought "maybe it's like my flowmasters and this will go away above or below a certain RPM" No dice, it just got louder and louder as the RPM went up all the way to redline. If that didn't make your ears explode, the noise it made when you let off the throttle did! Now I'm sure that this was simply because of the headers / no cats setup of this particular car. The owner liked it, it physically made me ill.

It just goes to show that what works well on one setup may not work well on another. This "quiet" exhaust was turned into an ear splitting nightmare. Given the ability to hear what it sounds like first, nobody would duplicate this setup.

All and all it's a matter of personal preference. Just because one exhaust is "louder" than another doesn't mean that it sounds better than another. It's all about finding that tone that sounds right to YOU.

 

The very reason I made my change.

My point was in reference to those saying Corsa isn't loud enough, or if they wanted quiet they would drive xxxx. What I'm pointing out is that volume will be achieved if you plan to start moving more than the stock amount of air through them. An aftermarket exhaust is often just the first step taken in an attempt to achieve a higher performance goal. Tone is, and always will be, personal preference. To use your example to clarify mine...one can't say that they don't like country because it's not loud enough. As you said, how loud it is, is dependant on many other factors. I would NOT want want you described from that C5.


My Dynomax were as loud as I've ever heard, but that was about it, they were just loud for the sake of being loud (these were the round ultra-flo race mufflers, I do not find their street performance, if you will, mufflers offensive at all.)

I see a couple more posts with sound clips have popped up. This is good, if the search function will keep all these posts accessible we'll have our own little database to help people decide what they want.

 

After hearing how quiet the 50 series deltas sounded like on a friends t/a, i opted for the 40 series. they are way more aggressive sounding in my opinion. so if you want something that still has a performance sort of sound, but you dont want it to be greatly noticeable, you could try the 50 series deltas. i think with most performance exhaust systems you will have more interior noise...its just a trade off.

 

Thanks for all your input. One of the reasons the exterior sound does not matter to me much is that I am always the one driving it and never get to hear it driving past me. At times it would be nice not to adjust the radio at a stop light. Currently I have a real nice sounding system from what others have said (no cats/just straight pipe to some mufflers unknown brand) but it just kills me having to turn the radio up then down. When someone calls on the cell phone I have to pull over just to hear them. Most of the time I do not hear the phone ring, which really is a good thing. I use my vette as a daily driver and it is stop light to stop light all the way to and from work. Somedays it can really get old.
I did enjoy the video in f minor and do not wish mine to be that loud.
Today I called a local salvage place and they told me they have a Borla system available. I told them I will check it out. New that system is pricey but used who knows that might end up on my car for the if its at the right price. I decide later I do not like it, I guess I will sell it.
Thanks again

 

You know my car is really strange about the whole cell phone thing. I try to avoid using it in the car whenever possible but every now and then I have to. I couldn't use my old cell phone in my car hardly at all. My new one though works great, even with the exhaust resonance I can hear it perfectly and the person on the other end can hear me.

In my case it wasn't so much the car as it was the phone!

 

Watch the vid in my sign if you wanna hear some Flowmasters at WOT.

 

Just had Flowmaster Super 40's put on. I love the sound outside and inside.At low rpm's when I need to down shift there is some resonance but when you put your foot in it, it sounds good.
I may look into a different y-pipe just to lower resonance.
