So Cal Suspension Posted December 19, 2009 Report Share Posted December 19, 2009 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". Quote Link to comment Share on other sites More sharing options...
So Cal Suspension Posted December 19, 2009 Report Share Posted December 19, 2009 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. Photos of the inside pipe after cutting. 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. Quote Link to comment Share on other sites More sharing options...
So Cal Suspension Posted December 19, 2009 Report Share Posted December 19, 2009 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!

papa_smurf49319 Posted December 19, 2009 Report Share Posted December 19, 2009 looks good sound any different? Quote Link to comment Share on other sites More sharing options...
So Cal Suspension Posted December 19, 2009 Report Share Posted December 19, 2009 looks good sound any different? I haven't run it yet, I didn't have any new packing. Honestly, I should have run them before I modded them. They were new (to me) silencers, and I never ran them prior to. DOH! Quote Link to comment Share on other sites More sharing options...

So Cal Suspension Posted December 20, 2009 Report Share Posted December 20, 2009 haha let us know how they sound i was going to do that with mine Packed the silencers today, they sound awesome. They're twice as loud as my PT hi-rev's. I love it. Quote Link to comment Share on other sites More sharing options...
GNR101 Posted December 20, 2009 Report Share Posted December 20, 2009 ahh good shit! might do it... they look somuch better cut Quote Link to comment Share on other sites More sharing options...
AKheathen Posted December 20, 2009 Report Share Posted December 20, 2009 too bad you guys don't have any sort of dyno sheets on this.............any noticeable difference in performance? should put some earplugs in and thry it out.........power/throttle response, etc.....

So Cal Suspension Posted December 20, 2009 Report Share Posted December 20, 2009 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 =) Quote Link to comment Share on other sites More sharing options...
