The Sparks system will KILL the FMF system by far. The FMF slip on is decent for what it is-for a full system it just doesn't compare though!

[Cotton26]

You can't go wrong with HMF, Sparks, or Rossier; and generally speaking you'll benefit more from a full system vs. a slip-on.

I have a yoshi.... I think sparks and Yoshimura are the best pipes that u can buy.

I have a WB pro meg exhaust with 8 discs on my 440. Works and performs very well. Deff worth the money.
