      Guys,

      I have an RLV silencer on my Stock Honda.  It has a short tube on the back of the silencer (maybe 2 inches) that is curved downward.  This causes the exhaust to blow on the rear bumper and creates a greasy mess.  I believe this was supposed to be some sort of noise suppression.  I’d like to just cut it off so that the exhaust would blow straight out the back.  Will this cause any performance issues?

      Thanks,

      Todd

      How about just twist the silencer a little and tighten the clamp so it blows the oil on the kart next to you?

      If I remember correctly, that rear piece has 3 screws holding it in, take out the screws and rotate the angled tip the direction you want.

      I think it is riveted together…..not screwed.  I could drill out the rivets and have the exhaust blow upwards I suppose.  I was not sure about doing that but I guess it’s not a lot different than having the exhaust blow straight out the back. 

      Thanks for the advice.

      That piece is for tuning. When that silencer shipped (new) it was sent with a curved outlet and straight. The curved piece is changing the back pressure allowing for a touch more over-rev.

      Actually Chris is correct here.  This silencer was sold as the one to get for places that required noise suppression.  The “tip” which is actually the entire end cap is riveted on, not bolted/screwed as it would be if it were supposed to be removable.  I bought it new and it did NOT come with a straight tip.  If it had, I would have just put it on there!   The reason I asked about the effects of just cutting it off is that I see different silencers (same ones in different lengths) being sold as ideal for short, medium and long courses.  I think I’ll just cut it off and see what happens.  I can always have a short tube welded on there if it has a negative effect on performance.

      Thanks for the help.
