definately not the miltek as i have one.
i had shorter tips put on mine as they stuck out a little too far for my liking.
when i fitted the 200 diffuser i had to do away with the inside exhaust trims on the diffuser and the exhaust still rubbed on the back of the outside exhaust trims.
you could possibly use a 197 after market exhaust if you cut the tips off.
best would be something the has same tips as a standard 197 system like maybe the ktek exhaust, you may still need to trim the point off the slash tip though.
