Hi all,

Trying to find the difference between the j's 60rs and 70rs. All I can find is info regarding the noise difference and how much louder the 70rs is. Is there any performance difference between the two? Or is the only difference that one has a larger diameter than the other? And what has happened to the 60rs in titanium? The FX pros look awful with the segmented tip.

Cheers

 

I got the 70rs. Not because it's louder (probably is), but because it's deeper. Performance wise? Who knows. If you're going supercharged I would have thought 70rs is better.
I think the 70rs is better up top, worse down low. With stock everything else though, I doubt any difference.

63mm has been proven to be the optimum size for supercharging an S2000

 

has it? could someone post up some results? i did have a search but it was all very broad!

 

Hmm I think the 60 will be the best option for me then really, although it looks like I'll have to get it imported if I want the titanium one. It's a shame they didn't make a 60rr as well.

 

If this is for a road car then don't waste your money on a titanium one. yYu wont notice the weight difference and titanium has a tendency to crack. Your much better off with a stainless exhaust on the road.
