I purchased the p-bomb header when I still ran the original can /w baffle removed. One thing is for sure...it does NOT do anything too quieten exhaust sound....like advertised.

 

The yoshi is about 100db and if it's to loud you can get different end caps to make it quieter.The MBRP looks good too and if you want to put their header on later I think you can still use the slip-on,that's not the case with the yoshi.
