Can you comment on any noise difference in the cabin?

Also, how much fabrication did you have to do to connect the header to stock (?) catalytic converter...

Last question - can you describe the "flange" where the header bolts to the cylinder head? Is there a flat metal 'plate' that connects 3 pipes per side? Or, is there a single flange for each tube?

Anyone with a stock head installed this? I know Bruno's done a flow job on his. :)

Thanks!
