Flowmaster 40 series

[JakeM]

Soon I will be putting a 3" exhaust with a downpipe on my '86 SVO and my friend tells me to put a 2 chamber 40 series flowmaster. I want it to be loud but not ricer fart pipe loud, would this sound good or not?
Any suggestions for a good, loud (but not high pitch or obnoxious), semi cheap muffler?

My $.02

There has been huge debates about flowmaster mufflers on our 2.3t cars. Plenty of 2.3t's run them, infact I have them on my 9L but wish I didn't. I don't even run a muffler on my 84, just a cat, but its only the 2.5" exhaust.

Ideally you want a muffler with a straight flow path, no baffles. Flowmasters have baffles in them. If you've got $$ to spend you can't beat Borla. On the flip side of cost is the Walker/dynomax Bullet , they are less than $40 iirc. Thats what I will be running on my car eventually.

Thats my opinon, one of billion of them out there. hth,

I drove an SVO with a 40 series Flowmaster and I didn't even think it was loud. It has a nice tone, and it's louder than stock, and not ricey.

But I don't think you really want a Flowmaster on a turbo car anyway...

I have 3in. with a flowmaster and I really like the sound. Much better sound than the straight thru stainless Dynomax Ultraflow which I pulled off after about the 3rd week, (Highway sound was unbearable). The only thing I liked better about the Dynomax was, You could hear the turbo whistle at idle. Very cool!! The Flowmaster delivered no noticeable power drop compared to the Dynomax.

pegasis?

Dynomax Ultraflow which I pulled off after about the 3rd week, (Highway sound was unbearable). .

That bad? I'm going to the bullets/ I don.t know how they would compare...

I've heard an 86 svo duel exhaust w/40 series and it sounded really good,almost like a V8 at idle! But on a single exhaust w/a flow master my 84 sounded ricey. Im gonna try a dynomax/turbo muffler.

So I'm still trying to decide what to do.....

What is the best borla you could get for an SVO?

I have 40 Series Flowmaster Deltaflow mufflers on my car right now. They sound and perform fine with no "ricer" buzz saw sound. There is a nice throtty rumble at idle and have no obnoxius drone or loud in-car sound at highway speeds.

I have a 40 series on my single exh.

I run a 2.5 flowmaster 2 chamber on my 85 with dual tip conversion with no cat and i love the sound. Everyone always complements me about the sound because at idle its kida sounds like a ricer but when you raise the RPM the sound is unique and sounds nothing like a fart pipe. At around 3500RPM+ the low tone of the flowmaster 2 chamber goes away and the exhaust gets quiet and soon the boost kicks in and all i hear is tons of air rushing out.

I will tell you that at UTI we flowed a 2 chamber and it didn't do that well. In fact, it did the worse out of all of em on a naturally aspirated car, they suck, imagine all the hurt on a forced induction. Even the Borla didn't do that great for its price. The best was a brand called Spintech. The muffler is nothing like ive seen before, it has tiny little twisted baffles in the case that it virtually flowthrough and those little baffles absorb the sound unlike fiberglass.

Edelbrock RPM series(basically a 2 chamber glasspack in a muffler shape, straight through middle inlet, middle outlet, very high CFM capability) is one im considering because it is true 3 inch, not 3" in and out and goes down to 2.5 in the muffler BullSh*t like Flowmaster.

Magnaflow is a pretty new brand and they were one of the best as well, they are also pretty much like the Edelbrock RPM series but they have the inlet at one side of the case(mirror like polished too by the way) and comes out the other end at the opposite side(extra qieting surface area).

Basically our cars, becuz of the turbo absorbing pulsations, in stock form are really quiet anyway, i've heard many with no muffler at all and they don't sound that loud. Im considering dual 3 inch from the downpipe splitting out to the front of the rear wheels with no mufflers, cats and mandrel bends. To top it off, those Hooker dual tips that have tiny fiberglass pockets at the end will take that ricer sound away without any restriction.
