While I love the design and interior of my GT, I am a bit frustrated that I can not find a way to access the engine compartiment from above, where the luggage carrier covers everything. I am a diy guy when it comes to my super cars, but I can not figure out with this one how to proceed (i.e. Replacing the cats with sport Cats....)
Anybody who can help me out?

Yes, I would remove the diffuse, and the flat undercover of the engine, but to replace the cat pipes, I need to attach the new ones on top of the engine to the rest of the exhaust system.And how do I get there :)? That's the problem....

You could ask the service people at your dealership.

If youre a mechanic or home mechanic, im sure you can figure out how to disassemble the entire car.

Its a MR car, so basically remove the rear bumper and diffuser is a good start. Even a porsche 911 you have to remove most of the rear to get access to the engine.

I'm sure the 570 is like any other cars, remove the clips and grommets and start unbolting everything you see.

No need to ask professionals for help lol. Theyre going to ask you to bring the car in so they can make money off you. But at the same time, if you can afford 1 of these cars, you can afford to bring it to the Mclaren mechanic to fix things up for you. ;)

Yes it is. On the S all you have to do is open the fuel door and remove the two or four (can't remember) torx screws. The engine shield can then be removed by picking up and sliding it back out of the grommets.

How bad of a contorsionist does one need to be to do exhaust mods on the GT?
In the market for either gt or an s but would probably change out downpipes on either model

Water / oil door... Not fuel door... If people start at the fuel door they'll be awfully disappointed when the door itself is the only thing that comes off :)

Did you figure it out?
Can you share your knowledge, please?
Thank you!

Not sure how you get the top off on the GT (I have the 570 spider which is pretty easy), but if you want to do the downpipes yourself you have the take off the wheels, wheel liners, diffuser and central metal flat cover panel underneath. Then you take off the O2 sensors, disconnect the pipes from the turbos (clamshell clamp), take off the downpipe bracket (about half way up), and then (when you’ve figured out taking the top off), disconnect the pipes from the catback section (olive clamps) and rotate the whole thing out. The rotating it out bit can be a nightmare tho - everything else is easy, especially if you have a lift.

Oh, and disconnect the battery else the pipe will probably touch the alternator positive line on the passenger side as you’re taking it out and spark quite a bit.. there’s also an orange pipe on the drivers side which I think is for fuel gases that needs to be disconnected just to get clearance.

The tech info portal probably has the info on getting the 570GT top off, but that costs $50/hr or so (mclarencars.techinfoportal.com).

Thanks!

I think that when you remove the panel that covers the Oil and Coolant caps there are a bunch of Torx bolts around that. I would start there, but there is a reason they made it the way they did. They don't want you messing with it. May want to make sure you don't void warranty by doing that stuff.

I do know that there was some discussion about a "shop manual" if there were enough people interested. Don't know what happened there...
