Hi I bought an 05 is300, I have a nice note out of the cat back I installed. But I would like to buy these 5 to 1 headers from the US for 170 AUD. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F332738594033
From videos I've watched, the heat generated can melt your stock intake, possibly melt the fuel rail directly above them and possible cause a carpet fire if I don't try and repurpos some bits of shielding. Any advIce would be much appreciated.
And yes I will be getting a retune after the header install
