Is this any good?

still not decided on headers yet! are these walkinshaw headers any good, I'm after VOLUME! and a reasonable price! is anyone using them?

The one on the right look like a stock ls3 manifold with a sport cat fitted.

That would be my take too, but I think all short headers look like that.

Your centre box will heavily restrict any noise gains these headers will give.

Remove that first, as shakermikee has done. The difference will be like night and day, and only cost £150-ish.

I think that might have been where the photo came from! sounds good though! the center boxes are going as well and a conventional "H" pipe getting fitted, also trying to find the right cam to buy, looking at comp cam kits online with high lift rollers. just need to start ordering stuff now and need to make sure I'm ordering the right things.
