Replacing Stock Mufflers With Super 40 Flowmasters?

I would like to get some flowmasters, preferably the super 40 series, the only problem is the smallest size they have is 2.25" and the exhaust pipe is 2". Besides that the super 40 is 13" long and im not sure it will fit where the current one is with a reducer.
So:
1. will i be able to fit the new muffler on with no other modifications other than a reducer?
2. Which one of the 2.25" mufflers should i get, center in center out, offset in, center out, etc...?

Center in, center out. I have them on my car. Not really a flowmaster fan, they were on it when I bought it.

I know super 44s sound pretty good. other flowmasters when you get on the pedal though it seems like the tone stays the same ,it just gets louder then starts sounding like your car is farting lol. Ive seen and heard friends cars and when they get to higher rpms it seems if it starts making the sound i was refering to.

44s and super 10 seem not to do that. idk to each is own.

I like my magnaflow glasspacks, no raspyness, no chatter, nothing.
has good deep tone in low rpms while cruising. When accelerating has medium loud deep tone. If you go WOT.. windows cracked they scream a deep loud tone to wear you cant really hear nobody in the car lol. When you go WOT... (windows all the way down) it gives off the same tone just not so loud in the car. When your deaccelerating it gives off a nice deep burble all the way til you stop. When idling its a low burble.. idk I like them alot, not bad for 29.99 at pepboys on sale.

you can always go dynomax bullets also .ive never herd them in person though. bt sound clips sound nice bt then again thats not accurate sound.

My personal OP is that flowmasters sound fantastic on the pushrod 5.0s. In fact I think a 5.0 with a small cam and flowmasters maybe the best sounding V8 of all time.... Just my 2 cents.

I want to do some exhaust also but mine is the 4.6. I have magnaflows on my SHO and they sound good but it is a turbo 3.5. Probably going to be a spring project for me.

I've always had the opinion that mufflers are somewhat tuned based on their location in the exhaust track. Flowmasters for early mustangs sound great located mid car, but sound crappy when mounted by the back bumper.

Late model mustangs have mufflers located where mn12 have theirs. They are a much better sound option IMHO. I'm very pleased with how mine sound. They hang lower than mn12 fitted muffs but I can live with that.

I agree ive heard sound clips of other 4.6 with magnaflow glasspacks like mine. They seem much more silent when mid car. Theres a clip of stang with them in the back similar, sound that i have. Also somewhere on here theres a guy that has pics and a video of his mandrel bent exaust. he has the glasspacks right after the differental, which to me his set up sounds badass...if you guys want to hear it i can find it and post the link

I like my mid mounted magnaflow, very happy with my sound.

My rear mounted Flowmaster 10 is great on my F-150 but might be kinda loud depending on your cat arrangement.

If you cut off the mufflers and run straight pipes it will sound the same as having the 40's on it.
The stock system is so restrictive it quiets it right down. When I finally ran true duels with 40's it would set off car alarms, but on the stock 2" system they made no difference.

I have 2.5 inch midmounted bullets true dual and its extremely loud, even with the downturns. People always tell me they hear me well before they see me. The drone isn't bad either.

But on a stock system? Better off just cutting the mufflers off and leaving it. I did that before I got true duals and it is much louder now.

Oh yeah, here's funny little story, I was leaving our small town grocery store and a little kid was walking by when I fired the car up and he about peed his pants he was so startled.

I agree with just cutting the rear muffs off for someone on a real budget. This is way better than buying some drone-masters.

YOu do get the "flub flub flub flub" sound though with this setup when you let off the gas which sounds really goofy.

yeah, don't get flowmasters... their designed to run in a much lower RPM range and sound terrible on an OHC engine that you have to rev the nuts off of for power.

i'm really impressed with my fathers stainless magniflow he put on his 4.0 ranger. it sounds quite good, but it seems so much quieter then it should. i would think on our 4.6 it would sound great at 5500

otherwise yes with the 3 cats, resonator and all the bends in our exhaust, without mufflers sounds like a mustang exhaust with stock mufflers, save the odd decel noise.

cut out that 3rd cat and the resonator if you want more noise

or just go where i plan and get yourself the mandrel-bent setup and a mid-mounted magniflow DI DO.

Or you could pick up my old complete exhaust that I've got sitting around that has Borla XR-1 mufflers underneath, it's all welded, and has polished tips... The only mods required would be to cut and change the beginning of the system for the headers to fit properly. I had this on my car, but I had a DOHC motor in it so the width and angles are different. It sounded very awesome and the mufflers alone are 130/each. You could have the thing for 250 and then have a true dual custom setup with all the hangers in place and just modify the first few inches that goes onto the manifolds.
