idea for high flow and very quiet exhaust. please flame.
alright, the basic idea is
long tubes
x pipe
dual reverse y pipes
and four mufflers!
what do you think?
i think if you split the exhaust by four
each of the four mufflers would recieve a less violent airflow
and so they each wouldnt be flowing as much air.
would it work?
i thought this might because when you push out more air,
it gets louder, right?
isnt that why the car is louder the more throttle you give it?
or after adding a/m cam? headers? ???
maybe i should wait till im sober..
btw, the reason for this madness is that all ive got is a GMMG on a basically stock car, and my dad is acting like a bitch already. that, and i want long tubes, but i live at his place.. so.. you see the dilemma?

THere probably aint enough room for all that and even if you did get it to fit it will still be loud. A better idea would be to run a pair of bullets b4 the x and a pair after. Or better yet stick to your original idea and add a pair of bullets b4 the x for a total of 6 bullet mufflers.
Or maybe keep your gmmg and get the headers. THen add a pair of bullets in the ypipe and add another bullet muffler in the ipipe.
Seriously, your best bet for duals would be to have a pair of bullets b4 the x and a pair of 4x9 magnaflow mufflers after the xpipe. This will give you the best sound and might be quiet enough for the old man.

Just curious what the point would be? Are you trying to have the most restricted enviromentally safe f body? Im sure there is reasoning behind this madness or you are just trying to get everyone excited.

Yeah, my comment is late...
I was going to say that your exhaust would weigh a ton, offsetting any performance gains.
I won't give any specific ideas, but I can give some basics you could think about to design what you want...
1) Exhaust gasses shrink as they cool. Therefore you don't need as large a pipe behind the mufflers as you do at the header.
2) Smaller pipe increases speed of the gasses, larger slow the exhaust gasses.
3) Smaller pipe is louder, larger pipe is not as loud, but has lower tones that will vibrate the old man's window when you pull in at night.
4) Slower exhaust gasses are easier to muffle, you can use larger pipe near the headers where it is needed, then use even larger pipe in a short section to act as an expansion chamber, then put smaller pipe out the back to make things flow well and quietly... in theory anyway. You can also use a muffler that has internals that are one size larger than the pipes before/after the muffler. This increases muffler efficiency without reducing flow.
5) Glasspack exhaust tips can be incorporated too without much weight.
Just some exhaust principles that you can think about. (sober)

that would probably be thee most expensive, complicated and most retarded exhaust system you could find on the market to get it to flow it would almost have to be pretty darn loud...by putting on 4 mufflers lets assume flowmasters because anything else that would actually fit would still be loud youd have a ton more weight then the stock ehxaust system or many aftermarket systems so no matter how good it did flow and it probably wont flow very well with 4 true mufflers on there it would be outweighed by the fact youve got a ton of weight sitting on the car...with my 98 s-10 we cut off nearly a full 1/2 second from 14.3's to 13.8's just by going to shorty headers, a custom 2 1/2in ypipe & a 3" catback with a bullet muffler with a dump before the axle...not only did the new exhaust system weigh like 40lbs(maybe more) less then stock it flowed alot better obviously. Theres no way around it either be loud & fast or quiet & slow lol or get yourself an electric cutout and dont tell anyone lol.

maybe i should take care of my tickets and warrants and then i can just have the lts and gmmg and the whole thing without too much worry.
besides me pappy,
there is the law, you know?
and in monteghetto,
i havent heard anyone as loud.
this converter isnt helping either.
im thinking if i go dual,
what about the Borla XS mufflers?
hooker maxflow would be another candidate.
this is from info i copied from a rustang site.
might as well put it up=

Here's my idea. Pay close attention...it's pretty complicated! Ok, ready?
Stock exhaust and an electric cuttout! How's that for quiet yet high performance? For even better performance add LT headers, a 3" into 4" Y-pipe, and get rid of the cats.

OK HERES MY SUGGESTION.. Listen to your father and SELL me the GMMG.
You will be better off with a STOCK setup if pops is complaining. And since I own my own home, I dont give a flying F&*# what people think.
so how 'bout it. 400?

If you want to modify your current setup, add a bullet somewhere (i-pipe) and add resonator tips. Pretty cheap overall and will reduce the sound a good bit (but not too much, plus zero loss of HP).
Stock/other quiet exhaust + electric cutout is the way to go though. I've done it once, doing it again on my C5.
