I'm running the Invidia N1. It's a tad loud on acceleration, but probably best bang for the buck. If you get it for the prices around 6-7 hundred, then the worse that can happen is you find it too loud and sell it off.

If you raw considering the evo3 it is significantly louder than the invidia.

+1 for the Perrin unresonated.

Seriously it is a personal preference but if built quality is one of your main concern, you might want to consider HKS hipower L spec or TRD. I have TRD on my frs, good built quality ,it is not too loud, it adds that low tone growl sound, and no drone. I was having hard time deciding between AP, greddy, HKS, and TRD. To me evo3 and AP was too loud. HKS was a bit too expensive for me. Plus with TRD, i did not have to worry about any legality or warranty issues

I love my P&L exhaust. Deeper note, no drone, and I don't wake the neighbors up when I get home. I think they are also offering a black friday 10% off sale according to their facebook.

agree with you on the AP. It's a bit loud and also fitment is not great .... one side is at least 1 inch longer than the other ...

Personally, I think the Evo 3 sounds awesome. The 3-4K drone causes it to lose some points in my opinion though. If I had to do it all over again, Perrin Non-resonated.

Perrin non-resonated.

Nameless has overpipe/downpipe combo with hi-flow cat and their axleback alone sounds amazing, check them out good price and also light weight

Go with SRT

just ordered perrin full header back... catless and unresonated...

You can't go wrong with the TRD, Nameless, Perrin, SRT, or the ARK exhausts imo. I have personally heard the USDM TRD catback, the SRT catback, the Nameless axleback, a straight pipe, and maybe a few others that I don't recall off hand.

The USDM TRD sounded the most like stock and was the quietest by far. I like the look of the tips. They fit the body lines of the FR-S well. Not sure how it would look on a BRZ.

The SRT catback (which I own) is loud, not as loud as the straight pipe but it is otherwise the loudest FT86 exhaust I've heard in person other than the straight pipe. I am not a big fan of loud exhausts, even though this exhaust sounds very deep and produces a nice boxer note. I think it has the best looks out of the bunch, but there are no dyno's available.

The Nameless axleback is in between a stock-like sound and the SRT. When you hear it you can definitely hear the increased bass in the exhaust note compared to stock. It's an apples-to-oranges comparison in terms of sound versus the SRT, though. The SRT is loud, rumbles, and sounds mean as hell under load, but the Nameless is milder while still being aggressive and burbly under acceleration.

The custom straight pipe was 707FRS's and was a completely different kind of loud compared to the SRT. Not only was it louder in terms of DB, but it just roared after 2k RPM.

And now, I have the SRT catback paired with a Nameless downpipe combo w/ Hemholtz resonator, which makes the SRT even meaner sounding, gives it a more of a hint of boxer, and quiets the drone.

You could go for the full SRT headerback, I guess, but I decided to do things in stages and make an unholy Frankenstein (SRT/Nameless) of an exhaust...I guess it turned out pretty well!

I love my Perrin!

I can't remember - did you stick with the resonated or unresonated version?
