I had this pipe on my savage for about a week. I had constant tuning problems and if you look at my post on tuning problems you can see all the problems i went through and tried to resolve. After about a week of messing with the thing i decided to take off my rd logics pipe and put my hpi pipe back on and all my problems were fixed. It seemed that since the pipe actually has 4 exhaust openings it doesnt create enough back pressure to deliver the amount of fuel needed at full throttle. The truck would bog down at full throttle and when it wouldnt bog down it had absolutely no power at all. Maybe this is only a problem that I have encountered but if others have, rd logics should look into this issue. I did like the sound a lot more out of the rd logics pipe, it was a quite a bit louder and had a much better tone, but its not worth it if my savvy isnt going to run right for me.
