My brother wants to install a full magnaflow exhaust system . My question is what the size of the Lincoln LS exhaust system?
Magnaflow

If it's your LS, just do mufflers. you don't need to mess with custom pipes. You won't gain anything but a different sound. The gen 2 exhaust was actually well engineered for flow.
If it's your brother's LS, what generation/engine?

+1, you can get good sound out of stock pipes and good mufflers out of the second gens

Mufflers only won't gain squat but a cat back will. The Gen 2 catback is so similar to the Gen 1 I doubt there is much pwer difference. Gen 2s got better manifolds and I think that is where the small gain of power came from.
Stock exhaust on all LSes is 2"
The MagnaFlow system is 2.25" They advertise it wrong as a 2.5"
If you go custom most go 2.5" as the crush bends narrow down some.
I'd tell you to search but there is alot of wrong info regarding exhaust on here.

OK, maybe I worded it wrong. You won't gain the performance necessary to justify spending 700 bucks on a cat back kit on a gen 2. Which I don't believe they make anyways.
On my gen 1 V8, I did 2.25" from the resonators back, since that part was actually smaller that the rest of the piping. Or so the shop said. The guy had already started before I got there in the morning, so I didn't get the chance to demand 2.5" pipe instead of 2.25.

1-2hp per $100 is normal for most cars. For some thats fine others want more bang for the buck...not really easy to do with this car.
The shop you used was kinda correct. Its the bends after the resonators and before the muffler that narrow the diameter of the stock pipe down. The pipe itself is technically the same size as before the resonators to the cat-back connection. Those bends are likely the most restrictive so you did improve it a little.
I'm happy with the MagnaFlow cat-back, its mandrel bend so no crush bends. And I happy with the power it gives over stock, even if just a little.

No system available for Gen2s so go custom.

If I replace the stock mufflers with Magnaflows will be there any differences ?

10-12hp is hard to feel.
The 40ish I've added some would probably expect to feel stronger.

HP very little.
Sound a little.
Thats why I feel just a muffler swap is a waste of time.
I wasn't trying to offend. In fact, I was thinking that the difference would probably only be seen on the dyno and on the track. For someone who doesn't take their car to the track, maybe 300 on mufflers and custom pipes would be a better option.
Oh, and just replacing mufflers and the pipes from resonators back gave me just the tone I was looking for, albeit a hair on the quiet side. Damn Lincolns and their sound deadening

Damn Lincoln LS's and their small motors
Much better.
My 87 LSC was plenty loud with all of it's sound deadener

I'm sorry guys If asked too many questions because I 'm not a gear head 
.
.Or if you are not interested in performance, and just noise, then get flowmasters. I don't know much about them though, so I can't guide you to which ones would sound good. I'd just search youtube for "Lincoln LS flowmasters" and see what comes up.
