Anybody use flowmaster mufflers?

[Radtap]

Wondering if anybody has specifically used a flowmaster super 44 on their 240 na or turbo and how did it sound? Got one laying in my shop, I wanna put an exhaust on my car soonish but all the mufflers I hear make it sound like a pos rice burner. Or any other muffler suggestions to give it a bit more of a deeper less raspy/tinny noise. My other idea is slap a cutout valve in there and straight pipe just to annoy the HOA and close it when they roll around

It will be drone-y. I prefer magnaflow. If you want something that sounds good, you're going to have to drop some coin.

I ran a NA side pipe with a super 44 for quite a while, lol. I did not like the volume but I do miss the sound it made. I'll see if I can find some old videos.

Right now I have a spun cat and a straight through 18" round magnaflow which was originally installed when I had the turbo engine but now back to NA it sounds like a ricer honda. I bet a chambered one will sound way better.

I don't recommend playing games with any HOA, that just sounds like a bad ending. However, on my NA, I have a round Magnaflow with stock pre muffler still in place. I'm happy with it. They're both straight through, and it is quiet enough that it won't bother anyone

I was thinking the chambered ones would help with the drone, I’d be daily driving it and most of my drive is 20 minutes straight down a long road so wouldn’t wanna hear that to and from work everyday, car is na now but will be turbo here pretty soon, my other thought is upping pipe size to reduce some of that drone and rasp

Historically few people like flowmasters on a 4. I run one on my V8 740 and love it

I have one on a lemons wagon. Sounds rad at idle. Like a v8 almost. Seems ok but it is super drony on decel in upper rpm range.

I had one on a LS1 powered 4th gen Camaro. It came that way when I bought it. I hated it. It was about like being in a P51 Mustang. I couldn't hear anything over the drone of the engine. The spectators loved it when I Autocrossed the car.

Mine doesn't drone. I think I have one with an extra chamber. Mine is 3 chamber

The one I had looked literally like a box. It also dumped right past the rear axle which did not help matters.

Yeah I know they’re not really 4cyl mufflers but I have two collecting dust after I straight piped my buddys challenger and thought I might give it a go if anyone else has, I have a couple cherry bombs but I’ve never liked how those sound on smaller engines

[Dvroofer]

I have a super 44 I could try out and let you know if that’s what type your looking at. Never ran it on the Volvo but great in a pair behind a v-8

Ive just been running glasspacks backwards so it flows better. I was afraid it would be to loud but with turbo its sounds great. The guy at ex. shop said flowmasters are great but they have problems with the baffles coming loose and rattling but did say that takes a couple of years.

[mikep]

Wouldn’t a pair behind a v8 be two 4cyl mufflers?

The 44s I have we’re on my buddys car from 2010-2019 and the baffles are still rock solid, I’ve never heard of that and I have a decent amount of experience with muscle car exhausts but I guess that can apply to any chambered muffler, I’m gonna have to replace most of the exhaust system when the turbo goes in anyway, just looking for good but not obnoxious options

Looks like the video links are broken? Damn shame I wanted to hear them, might not work on mobile though

[2turbotoys]

I like these: https://www.summitracing.com/parts/i...xoC9pcQAvD_BwE

They sound good and are way thicker steel then Flowmaster or Magnaflow, they last twice as long and cost a lot less.

[Radtap]

Got any video of it I could hear?

[2turbotoys]

I don't have any vids, I used them on my 740T build years ago. I bought 2 for my LS swap but they aren't on the car yet.

Here is a couple other peoples vids, tons more out there but you can google them

Borla ProXS is still under $100 and sounds great on a b230. I had an NA 240 with a Flowmaster and it had a lot of drone and didn't really sound good anyway.

[dl242gt]

I used a 2.5" flowmaster on my turbo and it was louder than I'd like but the real fail was the internal deflector coming loose and making a horrible screeching sound as it moved around inside. Upgraded to a Dynamax Ultra Flow SS and enjoyed that till I went up to 3" Magnaflow.

[culberro]

Any aftermarket round or oval can “turbo” muffler. They will have no baffles, some sort of packing, and will have the least amount of drone on a 4cyl engine.

I’ve used flowmaster and other chamber style mufflers on multiple 4cyl cars, they all sound terrible.

Use a Cherry Bomb in the middle and the Flowmaster at the end. Or the other way around.

You don't say how big the Cherry Bombs are, but another thing you can do is split the exhaust into two pipes and install one Cherry Bomb towards the beginning and the other towards the end then recombine the exhaust. The 2 un-equal lengths will help prevent drone. It's basically tuning the pipe for two different resonances and they each have louder and softer RPM ranges. The trick is to make them out of sync with each other so the overall volume stays similar.

All of this ****ery may be too much to fit under the car, but it does work. An exhaust system is basically a big trombone.

Idk mine sounds really good at idle with an rsi cam. It wins the idle award for sure but not in the rpm range. Especially on decel.

[Radtap]

My main goal is to find a setup that’s somewhat quiet at idle/putting around but hollers when I step on it, my neighborhood is all old folks and I leave for work early in the morning so I doubt they’d enjoy hearing me fire up cherry bombs every morning. If I can’t find something like that I’m just gonna slap a cutout on the down pipe and just dump slightly under the firewall. I side dumped my buddys 740t right underneath the rear door and all it had was a blown out cat, it wasn’t obnoxiously loud even when stepping on it but it sounded like a straight up tractor. Didn’t drone though, iirc the exhaust was the original 2inch pipe and then after the cat I upped to 2.5inch, gave it a little throaty tone but we were just dicking around
