Would having cherrybomb glasspacks on dual exhaust be too loud .. like a glasspack on each side?

Is having a conversation while cruising a priority?
Is hearing yourself think important?
I think a lot of people underestimate the ability of the 200 to make lots of noise. I've had muffler guy after muffler guy tell my that there is no way my 200 will be loud with flowmaster 40s. I went with 50s which are supposed to be quieter...and they are still loud.

I used to run cherry bombs on a Chev SB I had. It was pretty reasonable for noise levels. However, the Ford 6 is capable of making quite a racket.
How about using a resonator to 'tune' the exhaust note before it hits the mufflers?

actually i would be with gtm1086...i have had a glasspack and straight pipe...and in the car the straight pipe is actually quieter...plus its a way nicer sound without the glass pack unless u go dual.

I'm running a single glass-pack off the exhaust manifold (only because the auto parts store did not have a cheap turbo muffler, at the time). It sounds like a sick cummins diesel at higher rpms, but idles well and it has come to be the bronco's signature tone. Cab noise I cannot tell ya, for the bronco has never had a top on it. Good luck.

For S&G's I put a cherrybomb glaspak on my '63 Falcon Wagon for a GoodGuys meet to run with the Hot Rods . I live about an hour away and at first it was cool riding with the mighty 170 blasting out. I could annoy even the ricer boom cars with fart cans!. After cruising at speed for a while I started getting a headache and by the time I got there I was ready to rip it off altogether. I did drive it home - and put the muffler back on.
The sound at cruise speed reminded me of when someone cracks a window open on the interstate and you get that painful low resonance. It actually sounded pretty good outside but in the car speaking and hearing was distorted and almost impossible. Uphill under load would create a drone sound moving in frequency as the engine and road speed changed.
Someone on the forum a while back recommended JC Whitney 'high performance' mufflers. They look like glasspacks but are actually 'turbo' type mufflers with real baffles. They are @ $ 25 each and available in different id/od's and lengths. I haven't actually heard them though. so I'm just throwing that out there.

Maybe I'm getting old, or maybe the ricers have made me sick of listening to loud exhaust. I wouldn't go with glasspacks. I agree with powerband's experience. It's cool for a little while, then it becomes downright annoying.
I've always run plain old turbo mufflers on my cars. I use either Thrush or Dynomax. They both seem to flow well, and you can actually listen to the stereo when you're driving. Hey, for 20 bucks, it's good to me.
I think those JC Whitney units are called turbo tubes, I've seen them in a few places, but I've never heard them.

okay cool thanks a lot guys 
I got 3 Pursuit 170 badges on ebay from a mate in AU, only one was usable the others were badly pitted. I get a questioned about it all the time from other log-heads .
The bid was @$6 and change USD. I sent him a ten in cash along with some pics of my cars and he sent along the badges and a nice note.
I got a real kick out of sending ten bucks halfway around the world for the set. Talk about world trade!.

Hmm ... its soo even sided .. the pros and cons, ahhh. But i mean, i do WANT LOUD ... but i want a good sounding rumble. Hrmmm ... and flowmaster = expensive...

I have a cherrybomb on my car currently and it doesnt seem that loud, it just sounds nasty... the old rusty crap buick sound.... I dont like it I am hoping to do the flowmaster 50s, I really have only driven my car once but I was too busy trying to keep it straight, keep my eyes open with the wind and dirt (no windows whatsoever), and look for cops (I am 15 with no license driving by myself, with no seatbelts, brake lights, turn signals, back bumper, and other stuff. but with the 40 mph wind and sand, and the constant squeal of my tires (that much out of alignment).... it was funny.....
In a few months, I'm doing my exhast system. I still have the remaints of my dual exhast Cortina V6 system, which was a nice set-up.
The exhast signal must not ever reflect back up the pipe, but shouldn't just escape like some 3" fart can on an Accord, either. When exhast pipes are made too big, scavenging is lost, and it drones.
If the ricer mob has taught us anything, its that big tail mufflers on there own are a nasty, droning mess.
America has lost what it knew from the old days of hot blue flames and flattie lead sleds. That is that the pipes can stay a stock diameter, and that a set of good glass packs combined with some big 3 element items will make your ride deap and baritone, not a Benedictine Monk being tortured.
In Australia, Lukey makes some good points on what good exhasts should have.It's clear that the ideal set-up is to use a basic early V8 Mustang set-up, close to stock, nothing fancy, and run it from a dual exhast header, under the crossmember hump on the passenger side ( your right) then to an H pipe to two 19" long Cherry bombs. High-Performance Muffler, 19" Overall Length, 1-3/4"ID Inlet & Outlet Each ZX222855R
These are simple acoustic deadeners, and operate by a mixture of absorbtion and constriction, which take the sharpness out of the tone. They mellow things. So long as the pipes out are quite small, 1.75 or up to 1.875", these can link to the 3 element mufflers at the back.
The normal dual 3 element mufflers most K codes etc ran can be replaced by something like the 50 series Flowmasters, such as Part Number the 2 1/4", # 942453 , or as small as the 2" # 942053. These are a mixture of acoustic reflector and constrictor. They only have to be able to flow about 330 cfm at 1.8" Hg to give 150 hp a piece when normally aspirated. That's and easy 300 hp with tiny 1.75" to 1.875" internal pipes in most spots. With nitous, over 180 hp a piece.
The rule for power is that its cfm that rules. Above 2", exhasts fail to efficiently quell sound. If you stick with smaller pipes, you'll get great sounds, good low speed torque, and there is no reason your back pressure isn't a tenth of what it would be with any stock set-up.
It's nothing for a stock six cylinder exhast, like my old Falcons 1.875", to have 6" hg of back pressure. You can reduce that by half just by doubling your exhast system to dual 1.75". There are gains of 1.3% hp for every 1" hg of backpressure you loose if you jet the carb right. 4% more power just by doubling. Around 18% extra power by running headers. If you then run two flow masters, its just like running straight pipes for flow, but they are many decibels quieter. The minimum requirement is to define what engine hp you realisticly want to run, and double it. A big 3" Series 50 won't cover off the noise like a couple of 2" 50's will.
Summing it up, there is 25% more power to be had, with no major increase in noise if you use garden variety pipes, resonators and spend big on not-so-large flow master 50's.
I ran a big single in my Cortina, have listend to lots of XR6's sounding worse after pipe mods and they didn't sound that nice. Over here, Chrysler Hemis had an awesome sound that prove duals can sound sweeter. Like comparing a couple of Winton M's to big brass tuba.

So, exhaust drone is somewhat directly connected to pipe size, and especially the pipe behind the muffler?
for my 250, I was planning for cleaned-up cast manifold, 2" pipe, a single glasspack turbo muffler by Edelbrock in front of the rear axle (V8 location), 2" routing over the axle and a turndown instead of straight tailpipes.
.
is that setup likely going to drone?
I don´t worry about loudness, its that super-low humming tone at cruising speed I´m trying to avoid.
