bet that stock piping in the middle keeps the flow 40 sounding nice, not overly loud

Depends what year. All mine have been around 1 7/8" ID. I think my '88 4runner's was more like 1 3/4"

Just to finish up...I did get my Flowmaster 50 installed this last week, here's my impressions so far:

- Sound: Quieter than I'd anticipated. Quality of sound is good, not buzzy at all and nice idle...but I think I'd maybe have been even happier with a 40-series. Can hardly hear a difference from the cab.

- Power: Not a very noticeable difference. I think the Magnaflow cat cut down on felt power a good bit actually, I'd had a punched out stock cat on there before and I swear it felt freer.

- Mileage: City seems about the same, haven't been on any long trips so can't say for highway.

All in all, I'm pleased with the muffler...less so with the cat, but that's probably just the deal with having one period. If I were to do it again I'd go with a 40-series muffler, the 50 really is very quiet and I like a little more rumble.

just let the muffler get broken in. those were my same impressions, but after a few months, it got louder and gave a little bit of power. i dont know personally how the 50 sounds, but mine was super quiet when i first got it.

Interesting. That's good to hear, makes me feel better.

Just wanted to dig up this old thread to add my data point for anyone who is searching for the right replacement muffler. It's somewhat unique because I put in a higher flow muffler without changing the pipe diameter. People wondering how this muffler sounds compared to that muffler will have a good answer.

For reference, I have a 1994 2wd xtra cab pickup. Bone stock motor and exhaust though, I cut a 1.5" diam. hole in the airbox years ago thinking it might draw more air that way.

My stock muffler had a couple small rust holes forming so I got the 50 series Flowmaster Deltaflow (whatever that means) 2.25 inlet/outlet. I took it to a local builder with a good amount of experience building full race cars and exhausts and he convinced me to leave the stock exhaust pipe until it rots. His reasoning is why pay for new pipe until you have to? The new muffler is going to flow better than the stock one and with the small motor (22re), the 1 3/4 inch stock diameter pipe is perfectly fine for a stock motor. He said, when the pipe rots, we can open up to 2.25 if I want to but it mainly just gives you more noise.

For sound, I think the Flowmaster 50 series deltaflow 2.25 is about as close to stock as you can get. It is slightly quieter than the somewhat holey stock muffler that came off. It feels like it gets up to 70 and cruises at 80 a little easier than it did before but hard to say. I wouldn't say its faster but it feels less labored when accelerating and cruising at freeway speeds. Who knows if this is placebo effect or what...Maybe it will show up in improved mileage.

If you are looking for a 'high flow' muffler that is quiet, the 50 series is it. I expected it to be a little noisier than the stock can but I don't think it is. According to the mech, the larger diameter pipe will make it a little louder.

Hope this helps someone decide what's right for their application.

well magnaflows are stainless steel....... But if you want quiet and good performance straight pipe from manifold to any muffler of your choice.

The stock 22re header is very good. The cat (unless plugged) will not but any noticable back pressure on the system.
If you like to loose your bottom end and love 3600 to 5000RPM, then go for a (smallest street) header and big cat back (>2,25) Cat back 2.25" will give you a bit more useable power up to about 4.2K RPM

Anything bigger and you loose low end. Only a good idea if you do intake and most of all head work+cam. Then you have a race engine you cannot use on the street.

Hey ! First post on here after being on the forum as a guest for 5 months lol
What would you guys recommend on a 86 22RTE, I also have factory exhaust all the way back, id like to keep it quiet to mild and have better flow.
I have a few leaks so I'm thinking about upgrading. I was looking at one of those Flowmaster 50 Delta Flow. My stock Muffler seems totally fine though.
Suggestions ?

Can someone help me find a O2 wiring harness for my 1994 Toyota pickup 6 cyl, 4 wheel drive, manual?

pimacdaddy

Hey Derreck google Camelback Toyota Parts - Genuine OEM Parts, Thats where I get all my parts for my truck.
If you can't find 22RE Performance sell brand new 02 Sensors.

down pipe and exhaust at lesst 2 1/2" flow thru exhaust (unless emissions is an issue) even no muffler on the 22rte isn't too loud... I'm running a dynomax 2 1/2 inlet and outlet muffler on my 22rte with an upgraded CT26 turbo and 82 Supra AFM, and custom made downpipe...

Go with 3" of you can... with the turbo bigger is better when it comes to exhaust...

pimacdaddy

Thanks 87-4 Runner. Good looking custom pipe right there. Thats funny I was actually in the "Post Your Pics!!!" threads and spent 5 minutes drooling on the pictures of the 2 4Runner you have. Which one is the Turbo?
No Emissions isn't a issue. I am in Canada. I was looking at the different options when it'll be time for me to change the turbocharger. Whats the stock model... CT20 ?
Whats the dimension of that custom downpipe and what do you think about a catback ?

So many questions

87-4runner

thank you... the red truck is the turbo...
CT20 is the OEM turbo... the CT26 is the upgrade i picked because i wanted about 10 lbs boost with stock injectors and ecu...
the down pipe is 2 1/2" i have no cat... just a large diameter muffler....
ironically i couldn't find a 82 Supra AFM in the USA so i bought one in Canada and had it shipped here.... its plug and play

i also modified my charge pipe and rerouted thre lines for turbo coolent ....BEFORE

AFTER there is nothing on my charge pipe...

i did that mod because it was such a hassle to mess with everytime i needed to get to the turbo... now i take two clamps loose and roll it out of my way...

87-4runner

these were the pieces used to make my down pipe... the flange came from drift motion... for the ct26.... with internal wastegate

I deburred all the edges for optimal flow...

pimacdaddy

DANG that look so different than whats under my hood. Did you got the 4runner stock and than modified it that way afterwards ?
ALSO was the stainless hose welded to your charge pipe before ? Mine is welded to the charge pipe and wondering if thats supposed to be that way.

87-4runner

The first pic is stock 87 22rte...
I've done lots of customizing....
no i added the flexpipe to keep it from binding the turbo...
