Alright, just completed this. Didn't take too long, and I think the results came out pretty good. This was done on Original Powercore silencers.

Started with this. Standard powercore silencer.

After completely disassembling them, I measured and I didn't want to cut TOO much at first, so I went with 2 inches.

As you can see, now the inside pipe needs to be cut. Notice in the un-modded silencer the inside pipe is recessed approx 1/2".

Since I removed exactly two inches from the outside housing, exactly two inches needs to be removed from the inside pipe, in order to keep the spacing exact.

So at this point I didn't like the "downturn" tip, so I figured, WTF, I'll cut it off flush. I don't have any pics of that, but I just cut it flush with the end of the silencer.

Here's comparison pictures. I mocked them both up, to see if I liked the two inches cut off. I liked what I saw and duplicated everything for the second silencer.

 

 

And now for the finished product!

Basic power tools I used were a metal chop saw with a new blade, a power drill, bench grinder with wire wheel, and numerous metal files.

Let me know what you guys think!

Well, I never ran this setup (FMF gold pipes/powercore silencers) before I chopped the silencers. But compared to the Hi-Rev's throttle response is MUCH better. I think the pipes are what increased my throttle response. Like I said previously, the torque curve is much more smooth. It doesn't "explode" at higher rpms. It feels like it has much more power, steadily. The hi-rev's just didn't do what I wanted them to do. I spend alot of time mid-throttle, and the Hi-rev's just weren't the ticket. I think this setup will do much better in the sand. I can't wait until next weekend to try them out at Glamis.

When you get a chance get some pics of them installed. I want to see what 4.5" of the silencer cut off looks like. You must have taken it back almost all the way to the mount, right? Another unforseen advantage i noticed is, you use less packing =)
