Uk V6 GPF delete

[chrisday1990]

Hello guys

I know on turbo cars the back pressure sometimes needs maintaining, but on a the v6 supercharged are there any issues related to installing the tiny Miltek GPF delete ? Anyone done it before and regretted it for warranty reasons ?

It's not monitored, but the dealer might notice it's been done and hold it against you with respect to a warranty claim. Technically it could also fail an MOT but it's very unlikely an MOT tester would notice, nor be aware of the factory exhaust appearance. Perhaps the safest option is to remove the OEM cat, 'gut' it and then put it back. This way to the eye there is no appearance of modification.
