If you turn off the synthesize intake noise via OBD, you can hear the exhaust better inside the car. It also makes the car slightly quieter at cruising speed. Thanks for making the comparison!!!
Great content guys, loving the detail/explanation behind each install. Do you have a video with just the GPF delete and stock exhaust system. Would be great to hear what that sounds like. I'm after power gain/free flow rather than the sound of an after market exhaust.
That's great to hear! Unfortunately, we didn't test all the systems with the GPF-Delete, however the Fujitsubo was similar sounding to the stock system WITH the GPF, so i'd imagine with the GPF-Delete it would be somewhat similar to that as well. (Fujitsubo GPF-Delete @ 46:41 )
On my local dealer's list for a GR Corolla, so thank you for this and the intake video. I'm thinking it'll come down to HKS or Akrapovic, so I would've liked to have seen it here too, but this is a lot of help.
Thanks for taking the time to do such an informative video guys. I don’t have a Gr Yaris but really interesting video. If I did own one then I think the Fujitsubo would be the one for me!
Great comparison, that's for sure, but having the opportunity as you had, you just missed to try the stock exhaust with the GPF delete to see how it sounded like.
Saving like a mofo to buy a gr, want to have about 18k to put down so I own it outright, therefore I really appreciate the effort you put into this and when the time comes I will deffo look at purchasing from yourselves.
Brilliant Video made a tough decision even tougher 😂 one question is it illegal to remove the GPF ? Ie will it fail a roadside test or MOT. Also you didn’t really comment on what you thought to the Fujitsubo like you did the other other than it was quiet ?
Hi, yes tampering or removing any part of the emissions control system SHOULD fail an MOT and isn't legal for use on the road. It's me and my car on the video, I bought the Fujitsubo and GPF delete and kept them on the car. I really like the sound with the GPF delete, without it I probably would have gone for the Milltek Resonated or one of the HKS systems. Hope this helps 👍
Does anyone know how likely it is that an MOT tester would notice a GPF delete?? Also from what you say the Japanese market cars don't have a GPF so we just need some audio of a standard Japanese car to know what the standard exhaust sounds like without the GPF? Thanks for a great test!
Milltek are good, but personally I'd use a full Akrapovic titanium exhaust on my GR Yaris to reduce weight, or a HKS Super Turbo exhaust custom-spec'd in Inconel
@tegiwa superb review. Weighing up the Milltek or the HKS resonated systems. Do you have a summary of all the systems decibel readings in a single table? Thanks!
I'm looking for a titanium mid pipe gpf delete that will bolt on too stock exhaust, I like the quiet sleeper exhaust, but wouldn't mind a little note with some better flow and weight reduction. Possibly even a larger hi flow cat into a gpf delete with stock rear
Amazing video guys!! What is your advice... Looking for that free-flowing feeling you get from an opf delete with a raspy sound. No drone. But also lighter than stock too. I've had Akrapovichs in the past... What do you think about those? Happy for you to price up a solution for me! 😊😊😊
i've been thinking about the HKS Super Turbo Muffler for a while as it sounds great, but now i'm starting to wonder how it'd sound with a GPF delete as i want the sound a bit louder. unfortunately i can't find any videos of it 😔
@@tegiwa Yes he did say he was getting a bit old and wanted the quieter one for the neighbours i suppose - I'm also quite old too at 54 so I may have to follow his wisdomed advice. maybe not - think it will be the HKS. i'll be in touch when Toyota are! thanks again!
I've JUST bought a GR and came straight to your shop to have a chat about the GPF delete. Sadly your colleague was not very helpful lol. I've the HKS Turbo exhaust on mine. Did you fit the GPF delete on the HKS? As it's not on the video? Need to find out how loud it will be before ordering it through you guys.
Hi Mark, Unfortunately, we're not sure how loud this would be as we haven't tested that system with the GPF delete. If you was needing advice on installing it there is a guide in this video @41:00. We aimed to conduct as many tests as we can in the available time we had to work with, hopefully in the future we can expand on this video.
I’ve got a Scorpion on my S4, I don’t think I’d have another. There’s a reason they’re cheap, it must be the lowest quality stainless there is as it looks like it’s come off the titanic after being on my car for 4 years.
Gr8 test that lots of people have been waiting for. Personally I have Milltek resonated and it is as good as You say however longer trips can be a bit tiring. Also there is this drill at certain rpm that is not too pleasant. I was wondering to change it to HKS Legamax but am afraid that this will be again to quiet. Ps. Which one have You decided to choose for Your own 😎
@@Luki_Luki_Luki it means that I leave for work before 6am unfortunately 😂. I do love how it sounds though but if I wasn't fitting a GPF delete I would have gone with the Milltek Resonated 👍
Hi mate, largely depends on your dealer but most I've seen work on common sense. It would only affect things directly concerning the exhaust. For example, if you had an aftermarket exhaust that was misaligned and it caused one of the mounts to break on the gpf, then it wouldn't be covered. But if, say, the fuel pump stopped working, then that would be covered. I use RRG in Macclesfield and they have been fantastic
Holy cow, the GPF delete Remus is brutal. I do like the pure sound. It reminds me to real racing like wrc. But you absolutely can not drive this casually. Its just to whrooom. You will have anyone's attention. Mostly the bad sort. I wouldn't want that. For a daily, I'll stick with the stock one. Maybe the fuj.
Two questions from a newbie...does GPF deletion have any consequences when the MOT test is carried out, ie, will it fail and when you are able to obtain the new GR86, would you carry out the multi exhaust test on it please?.
The stock exhaust is very well designed, none of these are likely to make a difference to performance. GPF delete is the only thing that is going to make a difference on this video.
Unfortunately not. However for some slight comparison the Fujitsubo was similar sounding to the stock system without the delete so I'd say it'll also be somewhat similar with the delete.
The worst things about the GR Yarns fours is when you follow them on the motorway and you can see that shitty looking exhaust pipe hanging down like something has came loose.
