Taffman92 Posted June 26, 2013 Share Posted June 26, 2013 my DEP silencer on my DTR is broke, the weld on the last bracket has broke away and left a hole in the pipe and the weld holding the muffler on to the pipe has given way to so it just rattles around on the pipe, what I want to know is, I have a DEP expansion chamber on the bike, do I have to buy a DEP silencer or will another brand fit straight on like a Big One as I found a cheap one ???

Taffman92 Posted June 27, 2013 Author Share Posted June 27, 2013 nice one pay day tomorrow so lets see what my funds will let me get lol Link to comment Share on other sites More sharing options...
Taffman92 Posted July 4, 2013 Author Share Posted July 4, 2013 well, hadn't had a chance to go get the silencer yet witch is lucky in a way as the expansion chamber has all of a sudden got a big hole in it, resulting in waking my neighbors up in the morning ,making me deaf and a slight loss in power. so I will have to get the full thing that will cost about £175 for a Big One system , do I need any rubber mounts or anything?? at the moment the one on it is bolted strait to the frame .

finnerz89 Posted July 5, 2013 Share Posted July 5, 2013 I put a Big One system on my bike (dt 125x) fitted a treat. One of the mounts for the silencer didn't quite line up but it's not been an issue. one thing I would advise is to buy a couple of exhaust gaskets, decent ones at that because mine leaked a bit at first. And also maybe some exhaust putty just in case. One thing I will say about the big one system is that it'll need some looking after, as it rusts quite easily if you get any salt on it. Also maybe check your spark plug colour after fitting it, to make sure you don't need a rejet. Link to comment Share on other sites More sharing options...
Taffman92 Posted July 5, 2013 Author Share Posted July 5, 2013 ok will do Link to comment Share on other sites More sharing options...
Taffman92 Posted July 7, 2013 Author Share Posted July 7, 2013 Big One fitted a treat just like you said, the only mount that dosen't line up is the one with the spring on the front of the frame, don't need it though because you have 2 coming off the manifold , Link to comment Share on other sites More sharing options...
Taffman92 Posted July 7, 2013 Author Share Posted July 7, 2013 the only thing I have found since taking the bike out for a spin is that the expansion chamber rubs against the bottom of the petrol tank and can get a bit annoying, i'll try and fit a small piece of rubber between them tomorrow Link to comment Share on other sites More sharing options...
finnerz89 Posted July 8, 2013 Share Posted July 8, 2013 Sweet that's looking nice mate! Didn't have a problem with the expansion chamber rubbing on the tank, but then again yours looks a bit different to mine. Link to comment Share on other sites More sharing options...
Taffman92 Posted July 11, 2013 Author Share Posted July 11, 2013 and I think I've lost a little power on the top end, cant get the RPM above 7500 in 6th and it struggles to do it in 5th. Link to comment Share on other sites More sharing options...

YamYamMan Posted July 16, 2013 Share Posted July 16, 2013 Me and my friend both have DTX's I have a dep system he has big one and I leave him for dead....think it must be something to do with the back pressure I think Link to comment Share on other sites More sharing options...
Taffman92 Posted July 18, 2013 Author Share Posted July 18, 2013 I have noticed that the pipe that joins the silencer and the expansion chamber is a lot thinner on the BigOne than the DEP witch will effect the pressure I think. Link to comment Share on other sites More sharing options...
