My exhaust has been possesed by demons - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hello there..

I have a Nvidia Q300 exhaust, and I really liked it, the sporty but not obnoxious sound, a good improvement over stock but not super loud.

Enter the Jackson Racing C38 supercharger kit.

Now under just moderate acceleration the Exhaust sounds .. well it sounds like the trumpets of hell summoning demons to battle. It sounds like Andre the giant farting into a megaphone in a gas station restroom. Its LOUD, I dont like it.

So what is the quietest cat-back out there other than stock? I want to tone this abomination down a tad.

CSG touring is probably about the most quiet system to my knowledge.

Ran a fujistubo axleback that was very quiet. Very subtle over stock even with catless headers.

@RToyo86 I was actually considering the Fujitsubo Authorize S axleback because I had it on my WRX and liked it. Just got a twin again and it has the 3" Nameless axleback w/ 5" mufflers and it's LOUD. Like racecar loud. Which is surprising since the rest of the exhaust is stock.

Anyway the Fujitsubo looks nice, I'm just afraid it will be TOO quiet.

Quiet is nice. I especially love the Laguna 90 because it's tuned specifically to cancel that band of harsh frequencies right where the the engine is on the pipe. It's a sweet-yet-meaty tone.

Thanks for all the help!!

CSG is ordered.

That said, anyone interested in the Q300 that is in the central Texas area, I'll sell it and install it for $500 (it's about 5 months old) its the titanium tip version.

Sending you a PM about the exhaust

i just want to hear what demon-possessed exhaust sounds like

Clipdat · 03-12-2023, 04:52 PM

@RToyo86 or anyone else have any feedback about the Fujitsubo Authorise S axleback?

Hard to get an idea of how it actually sounds from the few static revving youtube videos there are of it.

Funny. I have TRD catback and I think it got quieter when I added the JRSC.

RToyo86 · 03-13-2023, 08:49 AM

EL headers was very close to stock, with UEL it was more noticeable due to difference in frequencies which also made it more boomy at low RPM.

Cruising some backroads with my EL setup. Windows up it's not far off stock, just a bit deeper done which you don't really pick up on camera.
