Swapped back to standard today. Took 6hours! Done a few miles since and the sound is definitely worse and there is a bit less torque. I'll get over it. Better they go to a good home rather than sit unused most of the time.
Sound is definitely better with the JS manifolds. More growl and a bit louder. Same increase as the sports cat on a piper catback I reckon.

Maxxed Ross? Him and ross/george are the only guys I've heard saying there weren't gains from them. I felt an improvement when I fitted them, I added heavy wheels too.

Any pictures of the wheels?

I think I've only heard of one person fully decatted on a road car, they kept a cat for MOTs.

One of my mates had them and his zs was the most powerful for torque and by some margin, of all zs rollered on the same day in a big group test when we roller'd about 12 at one time.

Is this Dave? And you are referring to Blue Harbour? They are his old set! I'd say a nice gain throughout the range.

They were in the pipeline anyway.

Will let you know if Red doesn't want them.
