So like the reviewer above... I noticed the rivets, but I got mine used and junky, so I decided to check it out. I mean it has to be some sort of restriction in the header right? Wrong. Just two pop rivets for absolutely no apparent reason. So grind em out if you want to see for yourself, but then you'll have to weld the holes up. Mines all sealed again and it seems like a pretty radical circuit. Simonini quality, super dope silencer, way sturdier than my old proma. Yep that's it.
hm......
