Default Flowmaster?

I live in a small town (I had to drive 2.25 hours just to buy my 03 OBS). All we have here is a Flowmaster shop. What does a Flowmaster muffler or full catback sound like on our Subbies? I'm going for tone, quality, and not too loud. No rice.

Definatly not ricey. Probably either a loud or a muted rumble depending on the specific muffler.

No first hand experience, but I'm guessing it would be very similar to Borla. Those two are direct competitors in every market they share.

Just went to the Flowmaster website - they don't show any applications for Subaru. Losers.

Plenty of people have put Flowmasters on Subies..... Just becuase it isn't listed doesn't mean it isn't possible. Remember it's an exhaust, almost any thing can be welded on.

I've got Borla Headers and a Flowmaster muffler. There is also an 18" resonator inline to help muffle the drone.


The sound is very deep and rumbly. No high pitch sound compared to I-4 motors.



This thread has a bit more info...

there is a big difference between Borla and flomaster:
borla is a straight through muffler and is just like a big resonator
flomaster is a chamber muffler

I have it on my RS its a series 40, with a Stromung straight midpipe (meaning without resonator)

You get deeeeeeeeeep tone which could be rather loud if you are used to hearing stock muffler all the time. But the whole design is different, so the inside is not going to rust out like say Stromung muffer. Some people will say that if its not designed for Suby then its not a good choice, but I like mine very much.

here is a video clip of my car with sound

let me know if you need me to make a smaller clip if you can't download it

Only mild steel stromungs rust out, but ANY muffler that's not aluminized or stainless will do the same thing. Thanks for pointing out the difference between the two though.

Default flowmaster

I am definetly thinking about a flowmaster 40 for my Outback after seein that video. I was wondering if you got a whole new axle-back section weled up or did you just cut off the old muffler and weld in the flowmaster. I am going to go get this done next week, so any advice would be greatly appreciated. Anything I should watch out for?
Thanks for your help guys,
Russell

Soon to have a Flowmastered Outback

A whole catback should only cost like $15 more than just the muffler, so I'd go that route.

Actually, the Flowmaster 60 seriese is the one that htye recomend for imports (check their website). I went with 40 series because the place where I got it from was out of 60 series.
However I really like my 40 series anyway.

I got Stomung midpipe and then the auto shop made the whole axelback section with flowmaster, with identical shape of stock axelback. I recomend going 2.25 in in diameter for midpipe and muffler section as I did some research back then and thats what most of the people recomend for N/A imprezas.

If you are getting series 40 make sure you get "Delta Flow" not "Original Flow" as the first supposed to be quietet with is what I have.

orndog, engine-wise only other mod that I have is RalliSpec Intake.

I also have borla headers and flowmaster 40 series muffler. I added a dynomax resonater inline to quiet things down. THe tone is awesome, really low and rumbly but in my opinion too loud. The 40 series is really really loud, INside i measured it around 98 decibals. Its even louder on he outside or with the windows down, I wasnted to go witha 60 series but no one in my area could get them in thetime i had available. I liek the sound but too loud for everyday use if you care about your hearing in the end.

Thumbs up Flowmaster is Excellent

I also have a Borla Header and a Flowmaster muffler with a straight 2.5 inch pipe and as that great clip shows the car sounds great. Flowmaster also has a limited lifetime thing.

WOW. That is the opposite of my setup. With the headers, resonator, and 60 Series Flowmaster....cruising at freeway speed, it's near stock noise level. Considerably more quiet than just having the muffler. Headers really bring out the true tone of the boxer motor.

Yeah, im guessing that is because you have a 60 series. The 40 series doesnt really muffle much at all. I love the sound but at freeway speeds (4,000 RPM) it really is too loud. But i'm young and can deal with it. Im also guessing that the elimination of both of my cats with a 2.25" test pipe made things a ton louder as well.

really, my 40 series is loud leading up to 4,000 rpm, but then if I am cruising at that speed on a free way, its almost dead silent, but then if you accelerate again it comes back to life
