I’m in San Diego. I have one on my STI with equal headers.

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.

Had it for 2 years with no issues. Even if they did this exhaust is right at the limit.

Yes stock hangers

So glad you enjoyed it and thank you for the support.

Gray lines my friend

Buy some those aftermarket hangers that are meant to sit flush and see if it looks better

@@santostuner where can I find them?

About 18K miles with this exhaust now. No issues what so ever.

thats fuckin cap LOL

Guess that's a high flow air intake

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.

@@Haylem I wouldn't say its crazy loud, just drones too much.

You not feel the drone in car very bad?

In general as long as the condition is good, I pay about half of what retail is when the product is used.

Generally speaking NO you are not. However it is best if you make sure with your contract before installing any aftermarket parts to be sure. Thank you for watching.

Catbacks or axle backs do not void warranty.

FWIW, my Subaru salesman specifically told me exhaust upgrades will not void the powertrain warranty

@@nthgth Thanks alot

Depends. Some might look away, some may say it's a no no.

Catback exhausts should not effect smog tests whatsoever. Only noise

Cat back doesn't need a tune it just changes sound.

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.

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.

If you watch towards the end of the video, the exhaust is measured by a decibel reader

@@senditpictures3436 i know, i did. but the revs to 5k broke 95db. i thought you had to rev too 20% less of peak power so 4400, and even then it would surpass 95db. I want this exhaust but i need to make sure it passes the db test so i can get a certificate

Refs don't go over 3k rpm.

State ref/law is at 2500 rp. This only breaks 95db at twice the rpm (5000)

Captain yes they are

Thank you so much for the feedback. It really means a lot. Yes I still (for now) have the stock bpv

@@senditpictures3436 Ty for the reply. Wow that is amazing, I do have the same cbe but your bpv sounds louder than mine, I wonder why is that. I have a MY20 btw. I assume in this video, you also have stock intake?

I have unfortunately been pulled over several times. Not once has it been or even mentioned about the exhaust.

Just cruise by. Upshift and drive like a granmy

Also, let it warm up and the sound goes lower.

Carried it over from my WRX. Couldn’t part with it lol

You need smaller and tighter fitting after market hangers

I used the stock hangars and just kept adjusting the tightness throughout the piping until I got it to a fit i was satisfied with. Thank you for watching.

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.

@@huehuehue-x3c 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.

@@ilysmwyhm he literally said "adding a catted downpipe" which is part of the turboback exhaust, not catback. I owned and sold one of these slow pieces of shit, I'm not just talking out of my ass.

Stop being a rude piece of slow thinking shit. Gtfo of interwebs, you'll do a favor for the rest of us.

Will need either an etune or protune if you get the DP. Also, Cobb access port.

No it did not throw a check engine light. I have heard of this happening in rare cases. Might want to check and make sure it is sealed properly.

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

Awesome, thanks!

Next Tuesday I will find out how it sounds on my 2019 WRX cant wait

plynexalize hey thanks for watching. Yes I did use the Grimmspeed adapter for the installation.

Thanks man great vid👍
