Repost here so it doesn't get buried. Been doing some research and looking at kooks large diameter shorty headers (1 7/8") From what I've read, it'll give me high end torque above peak rpm and be able to use stock h pipe/cats without a tune. Some low end torque loss for street driving (never really drive above 3.5K rpm on the street) but at the track I try to keep rpm close to 7k so I'm thinking it should work. Thoughts?
