The Most Quiet Exhaust? Catback Vs. Axelback + Fujitsubo Authorize R & S! - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

another one that's not loud is the JDM　STi one . just too expensive for an exhaust.

My fullblown dual 3 inch is very quiet and it uses a MagnaFlow muffler and no cats or resonators at all. Get a muffler shop to do a MagnaFlow 2.5 and with the factory cats in should be about as loud as the trd which is silly quiet.

Now the real question is, how to stay quiet with a completely catless exhaust system..

I've tried Tomei header, Motiv OP, Motiv test pipe with the Greddy Supreme SP.
Inside the cabin, the tranny noise is louder than the exhaust.

Just what I'm looking for! Thanks!

...side note, anyone with a completely catless setup, and the Perrin 2.5?

What size mufflers do you have on yours?

Stock header, stock catback, aftermarket frontpipe

I can second the Tsudo as I have the CB and FP. Although I do consider quiet (until you open up), I wouldn't put it in the same sound class as the Q300. It is one of the quieter exhaust though. Idle is extremely quiet.

I'm currently testing a version of the Authorize R Type S in the link above... probably the quietest thing on the market today.

In the cabin at freeway speeds, exhaust is impossible to hear.

Under acceleration, my engine is louder.

Will be doing some other dyno and sound. May try to get a comparable stock car for side by side comparison as well.

Man this is super to hear, I can now tell that this exhaust is similar to my Fuhitsubo Legalis r catback on the subbie which is quiet

Will need to consider this for my summer mod

I'm a big fan of my MXP setup. And you can get it much cheaper than the vendors here sell it for.
