1. How long have you had them?
Answer: 5 weeks
2. Are they becoming discolored?
Answer: Not really, they look Silverish/Gold, If you're debating on the Ceramic or Stainless, go with the stainless, nothings uglier than opening your hood to a rusty header, which is what will happen with the Ceramic over time, not to mention cracking. Have you ever read about a stainless steel header cracking? Rarely.
2. Did you notice more aggressive engine noise?
Answer: Hell Yeah sounds real awesome, especially with the Greddy EVO Exhaust and the AEM CAI.
3. Do you have any other engine/exhaust mods?
Answer: Just have AEM CAI, Greddy EVO Exhaust, and DC Sports 4-2-1 Stainless Steel Header. My car is 7 weeks old and has 2900 miles on it....
