If you click on/open the link above, at the top right it gives you the option to "Translate into English." No "Translate into American" option however. German car with the "delete"

Hey everyone,
we are currently working on an OPF delete solution. The pipes will be thermo insulated and, as far as we know, they are the only OPF pipes on the market that come with brackets allowing you to re-install the original rear silencer heat shield.
Removing the OPF will trigger fault codes in the ECU. We can disable these via a software calibration, however we are also developing a plug-and-play emulator module that prevents the fault codes from appearing. The emulator will also be the more convenient option for customers located in the UK.
I should have the first prototypes ready in a few weeks and will be testing them on our C8 and Z06.
We’ll also be running the setups on our dyno to validate performance, as we are expecting some gains due to reduced backpressure. If there’s interest, I will share updates, photos, dyno results, and sound clips once testing begins.

One question that hast to be asked is.. if the opf's were deleted, would the car fail it's MOT on emissions? Or even on visual inspection..?

Owners of 2020–2025 Corvettes may install an aftermarket exhaust system on their vehicle in an effort to change the performance characteristics or look of the system.
However, a number of exhaust-related DTCs may set due to an aftermarket system
resulting in drivability concerns and calls to the Technical Assistance Center (TAC) with questions about the proper operation of the system.
When diagnosing the exhaust system on the C8 Corvette,
begin by checking if the system has been modified with any aftermarket equipment.
OEM System
The Original Equipment Manufacturer (OEM) exhaust system on the Corvette Stingray is designed to meet performance specifications and deliver specific exhaust tuning. The OEM system is available with polished or black-colored exhaust tips.
It also has a matte-black-colored heat shield around the body of the muffler.
GM Accessory System
The GM Accessory exhaust system for the Corvette is manufactured by Borla.
It is offered with exhaust tips that are polished stainless steel, black Physical Vapor Deposition (PVD) coating or carbon fiber.
The GM Accessory kit can be identified by the slightly golden-colored tint of the heat shield.
If the GM Accessory original box is not available as proof of installation,
ask the customer to provide the invoice or receipt with the part number clearly visible.
If there are any conditions related to the GM Accessory system, contact Borla for technical assistance.
Other Systems
GM does not support any other aftermarket exhaust systems for the Corvette.
Other than the GM Accessory Borla system, all other kits are considered aftermarket systems and
GM will not cover any diagnosis/repairs or parts/labor costs associated with the exhaust system.
To address any conditions that may be related to the exhaust system, the customer has the option to have the dealership return the exhaust system to the original stock system, return the vehicle to the company that installed the aftermarket system, or have the GM Accessory Borla system installed on the vehicle.
These are customer-paid options.
If there are any questions about the exhaust system, it’s recommended to create a TAC case and attach quality photographs of the system.
Refer to Bulletin #23-NA-103 for instructions on submitting photos to TAC.
Any problems in how engine is functioning, and 3rd party exhaust has been installed, voids GM warranty and vehicle owner
will be fully charged for all repairs and service time
