It’s all to do with cause and effect.

so, for example, if you replace your down pipe, and say that down pipe changes the backpressure on the system, which in turn causes the turbo to fail, you won’t get the turbo replaced under warranty as it’s failure was caused by something you changed linked to it.
Ah I see. What is the likelihood of any issues from replacing a downpipe with a 100cpsi sports cat and removing the OPF? I’ve always heard replacing the downpipe is good for the car ... better flow for exhaust gases?

No, neither would invalidate the warranty as whole. As such, remapping would invalidate the warranty on the engine and transmission etc.

Depends, most likely the car will drive fine with the EML on. In some cases it may go into limp mode.

It would of course fail an MOT though.
Ok i see how it works now.

Minimal (although technically still a risk).

I was just using that as an example of a component having an effect on the overall system.

I could just have easily used, if you install a wheel spacer, and a wheel bearing goes, they may not honour the warranty on the wheel bearing as a spacer introduces bigger/different loads on the wheel bearing, compared to factory setup.

Any good practises for storing my OEM catback exhaust? I just left it in a warehouse at my work. Do I need to cover it or anything? Eventually I think i will put it back on the car

MG sent my dp with DHL a few weeks back but it got returned due to the new corona virus strain in UK. Waited for a bit but DHL weren’t delivering parcels to UK still. Paid an extra £50 to get it shipped by air and just received this ... an extra £200 -.-

I love the simplicity of the GPF cheat!

Let us know if it works for you - I don't think anyone has tried this with stock mapping yet.

Just ordered mine from an Aussie distributor. I'm worried about voiding warranty for valvetronic type exhaust.
Hopefully exhaust will sound better as Aus spec A45s are non OPF.
Hey @Medder,
What exhaust did you get? What's the retailer's name? I'm located in NSW. Cheers

I didn't get an aftermarket exhaust, just an ASR controller (exhaust valve module), so I can keep the valve in open position with a flick of a button. Exhaust note is a bit better than stock since our car are non OPF. But I'm thinking about the Akrapovic titanium Catback, not sure if I can use my exisiting ASR controller with this exhaust or I need to fit their sound kit to control the valve.
