I like the Jardine and Yosh equally. I bought the Yosh because it was cheaper.

 

They are all good exhaust sytems...I went with the M4 full sytem however I think Yosh sounds better than the Jardine..I sold my Jardine cause I did not like the sound of it...My buddies have Yosh and I love the sound of it...Like everyone said...Opinions will differ...Cheers

 

I love my yoshi RS-3C. You can find them brand new on ebay for $300.
