I have a set of the CPPA's on my grey car in my sig and they are still in good shape, one tube has cracked and I rewelded it at the head. The finish was looking bad on mine so we painted them with some flat black special high heat auto paint and that has been on them also for 10 years.
I would buy another set if I need some No Problem.
The woman's RR has the new nickel ones and mine are painted now.
Great Headers.
