Yeah, sure they flow better, but nothing to worry about for an exhaust system. Get what you think sounds the best. You make power with headers and a midpipe, not mufflers. I prefer the sound of Magnaflow over Flows.

 

well Im going with the bbk off road x pipe

 

Well go to youtube and check out videos with that x pipe and different catbacks. Exhaust opinions vary depending on the person.

 

Thats the best answer there!!!!!!!!!n Its all opinion and that will vary from person to person so its up to theh individual to decide when it comes to sound.

 

Agree there. pipes are for sounds.. get good long tubes and it will all be good.

 

Magnaflow I believe claims everything they make adds power, but anywho, a catback doesn't add more than 3-4 hp and so it's just your taste. I like my Magnaflow and think it sounds sexy whereas Flowmaster sounds like a older rough n' tumble car.

 

another person with the agree bandwagon.

even the flows sound great, I really like the smoother sound of magnaflow myself.. to me it sounds more professional and grown up. That and you won't suffer from the flowmaster drone on the highway.

 

you decide, that's stock vs magnaflow and stock vs flowmaster...

you decide,
Example: my bassani legit sounds EXACTLY like this when i keep the baffles in.

Magnaflow Catback vs. Stock Exhaust - 1999-2004 Ford Mustang GT - YouTube


you decide, that's stock vs magnaflow and stock vs flowmaster...

Both sound like crap in these videos. My Flowmaster catback sounded much better than this video. Was never a fan of the Magnaflow sound.

 

Drone is a killer. Thats why I ditched the Flows in favor of Magnapacks, I couldn't stand it anymore

 

And not all flows drone!

 

Flowmaster will give you the more oldschool muscle car sound.

 

mags are stainless and the flows arent (unless that changed recently?) thats where your $150 goes

Macs are the best of both worlds IMHO

 

They do make stainless steel Flowmaster catbacks now. I would have went this route if they made the SS Flows 4 years ago when my catback rusted through. I went with something newer and still chambered: JBA Evol stainless steel catback for the same price as an aluminized Flowmaster catback. I got it from ninosport.com, but they don't carry it anymore.

Here is the SS Flowmaster catback.

collectively.. here is your best advice...

YouTube - Broadcast Yourself.

 

screw both and go with lm2's. sounds way better than both mags and flows especially with other exhaust mods. this is with an o/r x.

Just doesn't do it for me.

 

i like my magnapacks, i was cheap 12 years ago and just had them welded into the stock stainless pipes. They still sound great 50k miles and 12 years later

 

For me an offroad pipe or even high flow catted midpipe and chambered mufflers sound the meanest. My MRT catted h with Flowmaster catback sounded deep and loud. Now my ARH longtubes with catted x pipe and JBA catback also sound great.

Just an example of flows with o/r pipe.

 

go with the one you think sounds best. I woulnt worry about the $150. If you are gonna do something, do it right the 1st time so you won't regret it later.

I chose borla stingers

 

 

Magnapacks®, and pay the extra $ for the stainless... will last longer than the car.

SHHHHH...Do you smell that?

 

flowmaster 10s with a catted x. sounds bonkers! and bcuz of the cats its not ridiculous like single chamber with no cats

 

thats my exact setup and you hit the nail on the head with the sound description with hi flow cats. Still have the Deep tone with the chambered muffler but its alot smaller than the other 40 series flows and that along with the single chamber the sound is VERY decent imo.

 

my exhaust with magnaflow cat back

 

Shopping Cart

that is the set up Ive decided on

 

it would have been easier just to Say what you decided that you went with that You personally like bc your "shopping cart" says empty.

 

magnaflows> flows imo. If you are in Seattle you have to worry about emissions so a o/r x may be an issue, get mil eliminators. having o2's turned off in tune don't work

 

Magnaflow will flow better, sound better, look better, last longer and fit better.

 

Magnaflow will sound better, look better, .

Some ppl like hamburgers and others like cheeseburgers thats not saying one is Better than the other purely opinion!

 

Here's a couple of vids of when I was running stock manifolds, Bassani O/R X and Magnaflows

 

I went with the BBK off road x pipe and the Flowmaster super 50 series cat back exhaust... I like the way it sounds the best and the little bit extra flow from the magnapacks doesnt seem worth the extra 100 since I like the way flowmasters sound more than the magnapacks..... Super 10s are just too loud for me they sound nice but really really too loud
