Ive been running 2.5" since purchased and wanted to try something with more back pressure to see if solved pinging issues. A FP3 solved that. The 2" had the same sound, just reduced level. I prefer louder so put the 2.5" back in. Running stock head pipe that is decat.

 

Ya I was still good with the stock de-cat and 3" baffle but with this FM pipe and it's just a touch too much , Drago recommended I go with the 2" , I'm also running an FP3.

 

One baffle near spotless, other shows some heat on wrap, right side, but all intact. Ran for couple months

 

I have a set of 2.25" with a couple of hundred miles on them. If you're interested PM me.
