TPI Specialties (TPiS) in Chaska, MN ---> http://www.tpis.com/ <--- has just started building their first batch of 20 headers. Their test V is due to hit the dyno next week to see the performance gains. In stock trim, their V made 333 RWHP and 342 RWHP after some programming.
Price for the ceramic coated headers will be in the $800-900 range.
Just spoke with Myron (owner TPIS)...coated and dyno figures next week. Under a grand "but" you'll also need to buy a pair of Cats to go with the headers...no crossover on the V system like on the C5. My long tube C5 TPIS headers sounded as good after five years as they did on day one...no leaks...solid product.
I'd get a set if someone confirmed that Kooks is not doing it after all. What diameter are they? Also, do they require a certain cat, I was looking at Magna Flow I think they are called, like $550 for a pair. Seems senseless to have these put in until Corsa is ready though. Do it all at once.
