Does this exists?

Is there a reason you don't want mufflers?

Asking for an exhaust without mufflers that's also quiet is like having a baby and expecting it not to cry.

A muffler is a silencer made with different chambers, and gases slow down in them, while a resonator is a straight drilled pipe with some glass absorbent around it. I previously had a NA 2000 cc with 180 HP, and I swapped 63 mm exhusts with 60 mm, and I noticed the difference (dyno too). Perhaps I'm sensitive. Supersprint factory is 30 km from my house, they don't use mufflers.

They make straight through mufflers too

Mufflers are made to lessen sound, resonators are made to remove certain frequencies of sound.

But how much of a difference? Did you swap out the entire exhaust, or just the catback/axleback? Nobody doubts piping size makes a difference and that theres a tradeoff between mufflers and resonators. If there was a quiet, muffled, exhaust system that doesnt restrict flow, half of us would have it by now. The other half would still be rocking 3" straight pipes on NA. Your best bet is to live with the noise, earplugs, louder music and go down to circuit sports and get you a resonated axleback today!

it doesn't matter what you say: people will still say that resonators make things more quiet. its like arguing with a flat earther or any conspiracy theorist

op, your axleback doesn't exist. if you want a quiet exhaust, use the stock one. if you want a quiet aftermarket one, I hear invidia q300 is very quiet. both of those have mufflers, as mufflers make things quiet. if you simply want bigger exhaust tips, ask and see if a muffler shop will fab one up for you

Do you know if this exists?

Welp, there is your original post.

Here is a quote from the reference you posted:

"For those who are thinking about just running resonators for their setup, keep in mind that it’s virtually the equivalent to straight-piping your exhaust. Resonators will remove some of the raspy, ping-y noise from your exhaust, but the volume will virtually be the same – ear-piercingly loud. If that’s what you’re going for, then great! If not, plan on picking up an appropriate set of mufflers to accompany your resonators".


Your call.

Ignoring terminology, is this what you are looking for?

Really, direct exhaust are not necessary more noisy than cambers ones. As I said, Supersprint is usually quiet as stock, or even more. I used IE Scorpion (UK) exhaust that was louder even if it had chambers...
This is an Aros exhaust (Italian) for BRZ. I’s straight and really quiet.

So, it looks like you found your exhaust yourself -

Nope... 63 mm... :-(

I hope the only exhaust you can find for any car forever only comes in 63mm.

Supersprint said once that there were NO GAINS with their axleback or even catback. So, what's the point to focus in this area? Only if sound matters ...

And they too have mufflers... They call them silencers... we call them mufflers.. http://www.differencebetween.net/obj...r-and-exhaust/
