Quietest Muffler for Turbo Car

Magnaflow is pretty quiet at idle and just driving "normally".

Just any magnaflow or is there a certain one that's meant to be quieter than the others.

And will i still hear the turbo no matter what.

There isn't a specific magnaflow muffler application for the z31. You'd have to select one of their generic mufflers.
Go to the magnaflow site ..

I've got a magnaflow .. (NO# 14815). Quiet .. maybe not as quiet as the OEM, but not distracting or attention getting at all. Step on it .. you'll hear a growl.


edit: I found the model no# of the magnaflow I have.

You say quieter than stock my car is basically stock except the p. o. Had the muffler cut off and welded a pipe in its place. You still cant hear the car all you hear is the 3 exhaust leaks on the crappy weld it sounds like the car has a dead miss. At a gas station I had a guy in a nova come tell me he could fix my car for 500 bucks because it was missing. I stuck my finger over the holes and said "that's a chevy guy for ya"

Anyways I cant wait till my down pipe comes I have an open appointment at the muffler shop.

HA … it appears that your situation is like mine was. My OEM exhaust rusted out at the intake of the muffler.
It wasn't that it was noticebly louder … it was just that the exhaust fumes were more noticeable.
It wasn't until I got underneath and looked at the inlet side of the muffler to see the huge hole .. :lol:

I saw the one you had. I guess I was thinking of a standard 3" in 3" out muffler to put where the cat should go then just have stainless sticking straight out of the back. Thats how it is now and I've grown accustomed to it.

i know what u mean the sound is just awesome u get used to it lol i have 2 1/4 piping to 2 1/2 end. it sounds so beefy ive had people ask me if i V8 swapped my Z31 lol…let me know how the 3" goes for you im still still undecided on it…nice sleeper btw!

talk to mrfishhat, he has like 9238409823409823 mufflers laying around as he keeps changing them out for quieter ones. so he should be able to point you in the right direction

Summit or Dynomax Turbo mufflers are known to be pretty quiet (compared to the usual Magnaflow, Flowmaster, etc). I'm not sure which one you'd need to fit, unfortunately. Another plus is that they're usually pretty cheap.

Chris is rightish about my muffler stack, On my SS ive had 4 different setups so far; mostly to hunt for more flow(ditching the 2.5in Flowmaster) And then to hunt for a quieter setup because the cops here in California are pretty strict.
1 Flowmaster - prettty loud
2 CM - much better in every way
3 Borla - louder then CM by quite a bit
4 Dynomax super turbo - 3in center in and 3in center out, still havent run it on the car since its not really running atm but it wins the put my cell phone playing music at max volume in the inlet and cover it with your hand so you hear it out the outlet test by far. if you cup your mouth so no air escapes and yell into it, it sounds no louder then a whisper. the borla didnt really even muffler on either of those tests. I cant wait to hear it on the car.

Go with the 3in and out centered dynomax super turbo. Its massive so it might not fit in the stock location out back, since it was designed for an f250. However, it should be pretty quiet and not totally break the bank if you make the exhaust yourself.

I was watching videos on youtube. I think cherry bomb has the best flow numbers. I sent the company an email about their quietest free flow muffler. Like i said before I will put the muffler in the stock cat location. Post a video of the dynomax.

How loud is the CM kit or did you just get their muffler?

You can also looking into resonators they go inline with mufflers to quiet down things a bit, also cats also help. I love the way a turbo car sounds with just turbo whine , blow off and waste gate.

No car inspections CO so no cat for me.
Theres plenty of open headers and straight pipes around and the cops don't mind to much but i don't want to be one of those. I like the turbo sounds just don't like the meow of our 3.0's.

Put this one where the cat is. Then straight out the back.
