How are you guys? I was trying to sell my car but hardly had any bites so decided to just finish paying it off and keep it, so now I actually want toget some PPE headers for it anyone selling some some or selling soon?
^^^^It's not about size, but about flow. PPE designed 2 different sized pipes in the ISX50 for a reason. The IS250 with it's smaller engine will be putting out less exhaust gases, so less flow. While the headers for the IS350 will work on the IS250 they will not be as efficient as the correct headers, but they certainly will be more efficient than the stock manifolds.
