This is just a quick video to show the sound difference between the stock exhaust on a 2019 Subaru WRX STi vs the Invidia Q300 catback exhaust system. It will also illustrate the decibel levels of the Q300 exhaust utilizing the measurements provided by the referees in the state of California. Please note this is not the exact model decibel meter that they use but it was performed in the same manner they will do it in at their required measurements. Filmed with Sony A7R3, Rode Mic, and GoPro Hero 7 in the cabin of the car.
Stay tuned for more videos coming soon! Thanks for watching and please subscribe.

For those wondering. I have the R400 and wish i'd gone with the q300 lol. Sounds awesome but there is drone. I do have a catted downpipe as well though.

how loud is it

YT has plenty of vids. I preffer Q300, sounds gr8 and not obnoxiously loud. Barely any drone, but who cares, it's all about sound and performance.

MY 2021 STi with Q300 sounds almost exactly like stock. MY car is completely stock other than the Q300. I notice you have some other mods done to your car as well because you can hear your turbo spool which you can't hear on stock set up.

@wadeharris3159 10 ай бұрын

I installed an R400 a couple of months ago and I’m realizing that the drone of this exhaust is just too much for me… I drive my STi as a daily, will the Q300 be significantly better in terms of drone?

Would you say this is one of the most "quiet" aftermarket exhaust? I am 34 with a new born and looking for a little more growl, but nothing too intense. I read online this is a great one for DD, but hits hard on WOT.

@senditpictures3436 5 жыл бұрын

Chris Haynes that’s almost exactly what I would say it’s like. I’m also in my mid 30’s and use this car as a daily with a commute. Didn’t want all the loud rice sound. Just something to let it breathe better and give it a slightly better sound than stock. If that is what you are looking for, I would highly recommend this exhaust. Cheers

How about smog testing? I heard you automatically fail visual test but sniff test you could pass, depending on the inspector. Do you have to swap everything back to stock even the intakes?

Love the sound, thanks for sharing! i’m looking at getting a 2016-2017 STI next year and wanted an exhaust that was an improvement over the stock one but not overly loud or obnoxious and this seems like a good fit. Do you know how adding a catted downpipe to a set up like this may affect the overall sound+performance?

@hecticphusion 4 жыл бұрын

adds performance and makes it much louder. you'll also need to get a pro tune for it or you'll blow up the engine.

@@hecticphusion Lmao, no. You don't need a pro-tune for a catback exhaust. It does a little bit of performance, usually about 10-20 horsepower for catbacks on STIs.

@senditpictures3436 4 жыл бұрын

From what I understand you have to adhere to what ever state your car is registered in. So as long as what ever state your cars laws are as far as exhaust goes it will be fine in California.

@kornukaz 3 жыл бұрын

IIRC you have 7 or 10 days to register it here in CA if you move here. If visiting - just tell the cop you are visiting. Out of state laws don't apply. Show him/her your out of state DL and you're good to go.

@chrisblue5534 2 жыл бұрын

No it doesn't your revs always have a higher decibel spike vs sustained. Notice how the 2500 rev was like 7 db higher than sustained 2500. The state reff tests the sti at 4200 rpm. They have you sustain it for 10 seconds. I am betting even though the rev to 5k hit 101 sustained 5k is actually 93-94db.
