What do you think of this:

It doesn't have any flanges, just slip fit joints and springs. It does feature an adapter flange to bolt to the stock cat or most downpipes but it will also slip fit to their downpipe. I haven't seen a pic of the downpipe so I don't know if its any good.

 

 

I'm really skeptical of the piping design, especially with the springs and all. I wonder how long that would last?

 

It should hold up fine motorcycle exhaust has been made like for a while using the springs to hold the pipes together. Plus HKS does the same thing with their Titanium/Carbon fiber exhaust and the HKS I had on my RS used the same setup. I know it looks funny I thought what the he!! when I bought a motorcycle exhaust and all there was were some pipes and springs..

 

Should hold up just fine! RS-R has good products!
Looks Loud though!!! Looks sweet too though!

 

With a down-pipe that would be really loud!!!!
