I've got an LS2 going in my project. It's rated at 400/400 from the factory.
I'm looking at 2 different sets of headers.

These have 1-5/8 tubes with a 3" collector.

These I can get with a 1-3/4 tube with a 3" collector.
Is there going to any difference on a street driven engine with the smaller primary tubes?
Thanks for any input.
