I know you guys are going to have a lot to say in the comments on this video... Here are a couple questions I expect people to ask: 1. "Full exhaust setup?" GrimmSpeed Catted Jpipe + Invidia Q300 Catback 2. "Are you tuned?" My car is Pro/Dynotuned. No, this is not a Burble/Crackle tune, just a standard one. 3. "Mod list?" If you want a full list of mods, see our previous videos. 4. "How is the drone?" It's pretty much gone at highway speeds with this setup! 5. "What's the difference between R400 and Q300?" Q300 has larger mufflers and double walled tips.

@petroleo4 3 года назад

I love my Q300! I have a son with autism and he is sensitive to loud noises and this exhaust give the best of both worlds. You will definitely hear it when u get on it. No regrets here.

@s14tan 3 года назад

The r400 looks great. But I honestly think the FA doesn’t sound great with it. Now if it had the subie rumble, That’s a different story. Nothing wrong with going for a more adult tone while driving around. 18 year old me wants more loud. 30 year old me wants more quiet. I like the change.

@err500wrx7 3 года назад

This is awesome, I was trying to find a Q300 vs R400 setup and to get it in the same car is outstanding! I think I’m after a “gentleman’s exhaust” so now it’s between this and the grimmspeed

Q300 is a gentlemans exhaust. If I wanted quieter it would prob be my first choice 👍

@andrereid79 3 года назад

I had the R400 installed on 2019 STI but it was a little too much on the freeway . The drone was obnoxiously annoying and having a conversation was next to impossible. That experience lasted maybe 2 . I replaced it with the Cobb stainless steel and I haven’t sacrificed losing the tones it a little more enjoyable when diving , I can talk or listen to music with any problems.

Soon finished working on the exhaust for my 01 bugeye WRX which I recently got. It had lost a couple flanges and the downpipe was leaking. Fixed and put the oem downpipe with cat back on for now. When that was all good I noticed a leak in the up-pipe too, so I got a $50 used oem catted up-pipe which I just gutted and is about to replace now. Otherwise 100% stock.

@axeya366 3 года назад

Hmm. This is very interesting and info on both exhausts. Had my WRX for a year now still running stock exhaust. Have a custom one on my Forester XT. Mrs does not like it as its too loud, so ive kept the WRX silent for weekend drives. Maybe in future might get the Q300.

@jamesg8246 3 года назад

I don't blame you a bit. We have the Grimmspeed catted Jpipe, stock mid pipe(which is unresonated) and the remark muffler deletes. Tons of turbo whistle and cold starts were pretty much straight piped loud. Rev matched down shifts were loud crackle pops... obnoxious teenager stuff. Not very neighborhood friendly and like you said, conversations when cruising were a shouting affair. I was researching muffled axlebacks and decided to replace the last piece of OEM pipe with a 3" stainless resonated mid pipe. Everyone told me it wouldn't quiet it down, just change the tone to be deeper. They were all wrong. It got deeper, turbo whistle isn't as loud which is a little bummer but you still hear it but the thing got a hell of a lot quiter. We no longer feel guilty about early morning cold starts and it no longer sounds ricey even with no mufflers at all. It honestly sounds deeper and less high pitched than that Q300 setup.

@SteveC-Aus 3 года назад

Good video man I just bought a Q300 for my 2020 WRX, nearly mid 30’s to old for heaps of noise and the FA doesn’t sound that brilliant anyway haha. With install, you recommend putting the Y pipe and mid pipe together before getting under the car?

@WRXGarage 3 года назад

Yes! Doing that makes it easier. Also, put the hangers on the exhaust first, that makes it easier

@pipes3 Год назад

I wish I had seen this video before installing the R400 on my 2020 STI. The drone and noise levels inside the car are absolutely ridiculous for a daily driver. You can control it some degree just city driving by keeping it in a higher gear (still obnoxious though) but on the highway you're stuck with whatever it's throwing at you. I just installed it last Saturday (5 days ago) and ordered the Q300 on Sunday. - the very next day! It's that bad. My understanding now is that it's actually significantly worse on the STI than the WRX - the drone inside the car specifically. Can't wait to get the R400 off my car. It's shame because it actually sounds really good otherwise - it's just not for me.

@Lorde360 3 года назад

Thank! I just found my new exhaust

@michaeltawil3057 Год назад

How much louder is the r400 turboback compared to the q300 turboback? Cheers

@WRXGarage Год назад

Depends on if you have a jpipe/downpipe. If you just have the catback, the r400 is a little louder, maybe a little more drone. If you have a jpipe, the r400 is definitely louder and has more drone. It's still not crazy loud, but probably a bit much for most people. R400 with stock jpipe is great though

@michaeltawil3057 Год назад

@@WRXGarage yeah both have downpipes. Does the r400 with the dpipe sound cleaner than the q300?

@747Durango 3 года назад

There are so many personal and valid reasons to do this. Will a Grimmspeed J pipe work with my Subaru factory catback exhaust? If yes, probably not as loud as the R400.

@edwinlopez8316 3 года назад

Love the content brother . I watch your videos all the time. I love the R400 quad mufflers but i dnt like the single rolled tips. I prefer the double rolled Q300 tips. Do you know if putting the Q300 tips on the R400 set up is possible?

@WRXGarage 3 года назад

I agree with you!! The tips are not removable on these, so you'd have to cut and weld them.

@skyraidfpv6753 3 года назад

It sounds good. I was originally going to go with a full Grimmspeed turbo back for a similar sound. Went with an MAP catted with ETS Extreme cat back no resonator no mufflers. LOL. It's loud and it's drones but I'm enjoying it for the time being. The car is my toy and I'm not concerned about having conversations in it. That said, if I ever get tired of it I can add mufflers!

@747Durango 3 года назад

How do you like the MAP catted, it is two piece, yes?

@skyraidfpv6753 3 года назад

@@747Durango Yes it's a two piece. The quality is outstanding and I like the flex pipe built in. Especially since there's no flex pipe on the catback I'm using. There's also a spot to bolt your ground strap back on.

62k miles! This setup is definitely a lot more incognito when casually cruising or on start-up, but opens up when you get on power.

Hey guys. Love the channel. I just installed an R400 and yah it's a bit too loud for me. I'd rather not purchase an entire cat back exhaust again. Just wondering if you have any advice for me to make it quieter. Would putting the Q300 mufflers on it do anything? Would they fit the same Y-pipe?

@WRXGarage 3 года назад

Yes the Q300 and r400 use the same midpipe and y pipe! Just the axleback section is different! If you can find someone selling a used q300 that's a good option

@bonotoli 3 года назад

@dewjustin 3 года назад

Was going to ask this same question! I have an R400 with stock downpipe at the moment, I'm curious if Q300+DP is around the same volume/drone. Would be real interesting. Btw the change is great, totally understand wanting quieter exhaust, the R400 even with no DP can be a little obnoxious at times.

@evand7810 7 месяцев назад

Hey seen your video and have the r400 love them but lately the drone has been killing me thinking of switching to the q300 how have you liked them I’m guessing no drone but can you still hear a deeper tone over stock

Yes for sure. Once the q300 is broken in, you still get a super deep tone and good volume on the upper end when WOT!

@WRXGarage 2 года назад

The STI rumble comes from the equal length headers, not from the exhaust! Aftermarket jpipe's on the WRX will definitely make the exhaust louder, but also improve the tone/deepness, as long as you pair it with a resonated catback. The r400 and q300 are both resonated.

@JALNIN66 2 года назад

Still sounds cool. Do you have aftermarket Headers? I have KillerB headers, Cobb Catted downpipe and R400. I can't drive by a cop without getting stared at or pulled over. Also Highway drone is obnoxious. Looking to switch to Q300 or similar.

@WRXGarage 2 года назад

Stock headers! The q300 is definitely a lot more stealthy than the r400.

@Zkt_Zkt Месяц назад

With Tomei UEL headers and up pipe and an invidia catted downpipe with the stock exhaust it rumbles quietly but when you step on it you wouldn't know it was the stock exhaust.

@Sabo69 2 года назад

How much louder is the Q300 compared to stock? and how much louder is it on the inside? I kind of like the quiet of the stock on the inside for a daily driver. But I want a bit more sound when I push it.

@WRXGarage 2 года назад

I would say the q300 is slightly louder then stock. I would rate stock 1/10 for loud and q300 2.5/10 for loudness. Q400 would be a 5/10. Axelback is prob 6/10 and any single exit will be the loudest like tomei
