Hmmm you know I actually never even considered altitude, that's a great point. Im at like 3000ft above sea lvl and no plan to boost my car. 2.25" Might be ok then. The one thing I will say tho, so far the 3 inch catbacks all seem to sound the best in any of the videos I have seen. Even tho it's possible to lose power that way, it's hard to argue with a really good sounding exhaust note.

I would think the designed in back pressure/ restriction the engine needs/is seeing is the header/over pipe designs and the two cats, doubt any reduced restriction downstream from there has any affect.. Last edited by LRNAD90; 02-04-2022 at 11:53 AM. |

3" catback was tested with *zero* difference in performance vs stock... as was a 2.5" catback.
Catback makes no difference in power, much like the first gen.

Any thoughts on the Corsa vs. CSGxMXP Touring86?
The stock exhaust with the sound generator unplugged is way too quiet for a performance car. I have no plans to do other mods, looking for something louder than stock especially at WOT with no drone at cruising. The car is loud enough thanks to tire/wind noise already. Perrin is temporarily ruled out because they don't have a 2.5" option Borla seems like it might be too loud but also piping dips down at the Y split Q300 - Had one on a previous car, it's fine, had some drone during highway driving, not noise but more like low frequency bass sounds Open to other ideas, but wondering how loud the Corsa would be during "normal" driving and if the CSGxMXP Touring86 would be barely noticeable over stock if i'm not doing headers, removing cats, etc. I have no delusions regarding performance, it will probably add nothing. Just want something to give the BRZ a meaner sound that isn't obnoxious and doesn't drone. |

For reference, Corsa's webpage has a $100 off deal running for their exhaust. Its still like $1,180 shipped after tax or something. IMHO, way too expensive for a noiser maker - but to each his own. |

I really like the sound of the Greddy Evo GT (also a 3" and honestly it is my favorite, can't stop listening to it), but I'm concerned it may be too loud, and don't like the huge low hanging mufflers (anyone else wonder if there are any aerodynamic penalties when you remove the stock muffler for something like these, since the under car airflow out the back could now be disturbed by the 'pocket' created by the missing stock muffler? Seems like they spent significant time with undertrays to control airflow on the second gen). The Corsa also seems really loud to me, in the only real video I seem to find (updated with longer video, doesn't sound as smooth to me as the others).. And talk about expensive, the ARK Grip sounds nice, but OMG is the price ridiculous.. Adding the Lachute Performance "Catback - Comfort " to my list of favorites, but reserving judgement till I can hear it under load. Honestly it doesn't sound much different than the Lachute Muffler delete pipe.. Last edited by LRNAD90; 03-09-2022 at 04:37 PM. |

The 2.4 is turning out to sound awesome. It revs faster, deeper and with no rasp vs an STI. The greddy GT so far has the cleanest and best quality sound. But it might be a bit too loud.

I recently started listening to the Corsa exhaust on YT, it's starting to climb to the top of my list of choices. In years past, going by old posts here, it seems like it could be had for a lot cheaper. Wondering if it's more expensive now because of shortages of everything else?
Also the more I think about it, I haven't found a single aftermarket exhaust that sounds good to me with UEL headers, and I'm not sure I've seen a catted UEL. I'd like that rumble but not so insanely loud and without the rasp and/or fartcan-like noises I seem to hear in everyone's videos... could be their camera though I guess. |

A few pages back, someone commented that the Perrin 3" might have some drone, especially vs. the 2.5". Regardless, it's not in stock. Even though it says shipping soon, I believe Perrin is waiting on inventory like everyone else. I also don't see the point of going to 3" if it *might* negatively affect power if i'm never planning on going FI on this car (and it costs more than 2.5)

Just pulled the trigger on the CSG Touring! Hopefully it warms up a bit by the time it gets here...
