Exhaust

Adding further to that there has been no publicised posts of claims been denied to due the removal of OPF…

What we all know is that if you have a modified car and you don’t declare mods such as air intakes/aftermarket exhausts, wheels and the insurance finds out they have the right to reject the claim but even then, there is many well documented claims that gone to the FOS and said complaints upheld if the insurer would have insured the car if the mods in question were declared at the time resulting in revised payout based on premiums had those declarations been made, same with not declaring points.

Most mods aren't illegal though are they, It's a legal requirement for a car with a OPF/DPF fitted from the factory for it to remain fitted, hence the tighter controls they build into the ECU to stop them being removed.

As said above most mainstream Insurance won't touch it, specialists maybe, but they aren't always the cheapest for insurance, so most RS3 owners are insured with the mainstream ones because they want 'cheap' insurance, and it's gone up a lot in recent years on RS3's.......

lol - its weird, when I drive the milk float the lack of sound doesn't bother me - as I know that's how it is .. and it does have a decent stereo :tearsofjoy:

So I wouldn’t be so sure as to say the insurance won’t cover them, maybe some won’t, I’m sure all the big boys won’t. You’ll find a lot of modified insurers that will.

I’ve asked specifically about coverage of decat and opf removal with Adrian flux. Even asked the advisor to go away and double check for me, they’d cover them without issue apparently.

What happens when it comes to a claim is maybe another thing but I’d imagine it puts them on a sticky wicket from a consumer protection standpoint if they’re will to confirm explicit cover for those mods via call recording and in writing.

As long as it's in writing they'll cover OPF removal, then great happy days, a specialist yes, but as you say mainstream insurer more than likely a no.

Won't stop the ones that say nothing though, who will be effectively driving around with void insurance.

If they do them to fit the 8Y it's a winner........imagine an 8Y going down the street with CZGB or even DAZA noise coming from it

So update on the insurance front, a-plan, will insure a decat/ opf but were up front in telling me that in the event of a claim if the vehicle isn’t deemed roadworthy the insurer might not pay out, seems obvious but I suppose emissions is a little different to a bald tyre. Seems a little bit of a con. I’m wondering if Adrian flux could shed any light, pretty sure they’re forum sponsors?

Has anybody in UK or europe with opf cars tried the AWE exhaust?
I reached out to AWE but they cant say weather our cars will work with their system without any modifications
 
Somebody posted this in 1 of the facebook groups. Anybody have any feedback??

but how can you cut the original downpipe and weld the two pipes together without removing it from the car?
 
@8YARWY they will never spot those missing parts when up on a ramp :tearsofjoy:

Bend the pipes down vertical(ish) to the car allowing the flexi joints to take the strain?
 
I installed miltek 200 cell downpipe without OPF . After some fine tuning the OPF seletron emulator seems to be working ( 300 km without detecting any error code with OBD eleven scan ) . The problem is the wastegate rattle .. I find it unbearable . I think I will remount the original downpipe . The wastegate rattle can be reduced with specific maps .... but the 8Y is still not mapped .

Hi is the downpipe de catted or sports cat? Sports cat would not cause as much wastegate rattle as the de cat? Also link for opf simulator?

I installed sport kat. I also hoped that rattle wastegate was not so obvious. However everyone has their own sensitivity .
Emulator is produced by the Italian company Seletron. You won't see anything on their site yet as they are fine-tuning the product. They made it for 8V FL and I am testing it on the 8Y . It is quite advanced . It takes RPM signal from CAM sensor and Boost signal from PREX2 sensor . It has a small ECU programmed to send plausible signal to the two OPF sensors. If I get to do 700-800 km without error codes the product will be really effective. The preconditions look good. If you don't install any emulator every 10-15 km the ECU registers an error and every 50-100 km the engine light comes on.

Good to know there's options in the pipeline that don't involve a full remap. Definitely keep us in the loop as things progress! :)

I’ve noticed the 8Y rattle on cold start.
Can’t hear it with the door closed but one day I had it open when cold starting and the noise was there, stops in seconds.
No where near as bad as the catalyst warm up phase bag o nails on my 8V, I’d taken that out anyway as I was using the Dyno Spectrum tuning system, as did I on the wastegate rattle which was adjusted between 1800-2500 rpm to stop the rattle noise.

Could george from burger tuning not help with the waste gate rattle on the jb4?

So i take it, its not for sale yet? As it sounds lile ide go for this one over the infinity performance package. Atleast with this one you can choose your own downpipe.
 
I do not believe that Jb4 can intervene on the control unit to make the wastegate work differently.
Yes seletron emulator is not yet on sale. Rightly waiting for results on my car . It will take me another two weeks to cover 800 km .
I am in contact with another 8Y owner who will soon install Seletron emulator . Will be fitting HG downpipe with two 100 cell catalytic converters modified by welding 4 temperature sensor studs.
I am curious if the wastgate rattle is more contained with this downpipe ,

It will be good to hear their thoughts. Hopefully the lights stay away and we can get this ordered.

I have travelled 450 km with the Seletron emulator and so far no error code.
I had the chance to drive another RS3 8Y with Miltek 200 cell downpipe without opf and the wastegate rattle could be heard on this one too. With the windows closed the rattle is much less noticeable.

Is it only on cold start or all the time that you get the wastegate rattle with this kind of setup?
 
You can clearly feel it from 2,500 to 4,500 rpm with a throttle opening of 20 to 70 %.

I will update you on the Seletron OPF emulator. It works, no errors in 1,100 km. However, error codes generated by no catalytic converter must be handled. They are generated every 300 km and are due to the fact that the two lambda sensors read equal values. Seletron is currently able to supply a device to be connected to an OBD socket that massively clears errors.
Regarding wastgate rattle if you use cars with closed windows you do not hear it . If you use it with the windows open it can be heard fine and in my opinion annoying.

I think so . The manufacturer is the Italian company Seletron https://seletron.com/it/ . Nothing official appears on their website, but I know another Italian RS3 8Y owner who bought and installed it without any problems (he has covered about 500 km at the moment). Contact them directly by email info@seletron.com .
I will remove my used one on the first of June ( I will remount the original downpipe for reasons I have already explained ) but I think it is quite complicated to manage a private sale outside the EU .
 
I ordered a BTM exhaust. It should arrive at the beginning of June. Costs madness but less than akrapovic. It seems to me better built than Grail and I'm sure they have studied sportback versions. I chose version with their electric valve motors. Seems to be more reliable than using original motors to move bigger valves than the original. For German homologation reasons their valve control keeps them closed between 30 and 60 km/h . For this reason I bought from them optional valve control ASR component CB2 specifically to be integrated on their valve control.
