how and with what to clean the exhaust pipes of a 360

[ferrari 360 spider f1]

im traveling day 13 th to a big ferrari event in salzburg austria of course i will post pics when i come back, i want to have the car just perfect clean and detailed i ordered allready zaino products
z5,z18 and z8 grand finale.
of course i will take all that stuff to austria also wheel polish p21s and p21s tire dresing p21 wheel cleaner,but now there is a problem THE EXHAUST PIPES are extremly dirty.
i heard in some forums that oven cleaner is pretty great i dont really know.
can i use oven cleaner on my golden 360 spider exhaust or they will get silver.
here in switzerland i dont find great exhaust cleaner they have only very bad stuff so i thought maybe oven cleaner will be better.
