Does this exists? - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I like how we spend two pages to figure out that no one is on the same page when it comes to the words "muffler" and "resonator".

I think what OP is asking about is exhausts without baffled sound suppression inside, i.e. he wants exhausts with straight through sound suppression design (aka resonator "design" not unlike what is on the stock midpipe)

95% of catbacks out there are straight through, the question of sound is going to entirely rest with the size of the resonators. Plenty of them such as Blitz, Fujitsubo, Greddy, etc. are quiet with straight through design.

Nope, I contacted them, they confirmed it's straight drilled pipe.
"Silenziatore" in italian is a device that silence. Ther's no strict translation for "muffler". We just call them direct exhaust and chamber exhaust.

Yup, that's the point. I'm looking for a straight through exhauts, like the midpipes are made. I'm sure that Milltek and Perrin are not. Fujitsubo is straight, but just Authorize R...

Well, if you think that an NA engine will make statically significantly more power with a 63 mm exhaust as compared to a 60 mm exhaust, I reckon your butt dyno needs calibration and your dyno run needs to be validated.

BTW, what is your take on light weight crank pulleys …??

humfrz - jest ah messen wich ya (sort of)

Sorry, never tried them...

Thanks everyone! Found! Blitz confirmed that their exhaust is direct!

Technically 60.5mm, OP will be more disappointed now.

Are we talking about OD or ID here?

What about the measurement(s) in the bends?

How many bends?

What are the angles of the bends?

Soooo much to consider ..

I asked a question, if you're not interested nobody forces you to post. This is a forum for questions and answer, if you want to make irony, this is not the right place.
In Italy we have a term for this people: bimbiminchia. Now, serch for a translation if you are cleaver enough.

I had no problems with your post up to the point where you wanted to educate us on what a resonator is vs what a muffler is. Even the link you posted doesn't distinguish between baffled vs straight-thru mufflers. Mufflers can look 100% like a "resonator" (and vice versa). The factory front pipe has a big resonator that looks like a muffler but is straight through.

If you want to argue about 63mm exhaust flow characteristics vs 60mm, this is not the right place.

In English we have a saying for this: "argue for the sake of arguing". No translation needed.

Checked translation for "cleaver enough", no luck , you win OP.
