ProMotoBillet Endcap, tried it?

Hey guys, anyone tried one of those Promotobillet endcaps with the spark arrestor in conjunction with a YZ muffler? If so, did it have any effect on noise things?

I have a YZ muffler sitting on the shelf that I was thinking about trying.




If you read my profile you will notice I am the proud owner of the item you mentioned. Yes it works awesome, The quality is top notch. It did mellow the tone down on my YZF pipe, but mine is a Euro model and they have a diffrent end-cap.(no down-turn) I would highly recomend it to anybody.
