If your bike dosent have piggy back (rear resovior) shocks than get a set of these

DHZ Dual Exhaust System

i was looking at that but 300 bucks for a exhaust is a bit much..

i have also been looking at this one

PIT BIKE EXHAUST Thumpstar 125cc 140cc PITPRO DHZ MINI - eBay Other Makes, Bike Parts, Motorcycle Parts, Accessories, Cars, Bikes, Boats. (end time 28-May-09 14:59:11 AEST)

this should fit on my bike right?? and how much difference will it make??

 

[wackojacko]

looks like a rip off of a BBR D-Section exhaust

 

[toddy]

will it fit?? and will it make a difference in sound??

 

[wackojacko]

is it the d-pro125r or the older 125

I like the video on the ebay ad looks like a good track

 

[toddy]

its a d-pro125 (one with the lifan 125cc) and its a 2009

 

[wackojacko]

DHZ sells these pipes at a good price every now and then :

They're pretty good pipes and should fit your frame ... the D-Pro pipe you're showing would be OK too if it has an oval can ... They'll definitely make your bike sound louder ...

The BEST pipe to get would be a custom built stepped header pipe with a reverse cone megaphone muffler ... I've talked about them before ... they increase power everywhere over any of the straight type pipes ... They do it by sucking the cylinder totally clean of spent exhaust gasses and create a stronger vacuum in the cylinder than the bore size can provide ... That in turn increases velocity (air speed) thru the carb which translates to superior throttle response , a broader torque curve and increased peak power thru velocity ramming more cc's into the cylinder than normally occurs ...

There's a dyno chart in the TT thread below and that Xr Evo guy at the end of the last page told them about the pipes waaaayy back in 2007 ... He even gave detailed pipe measurements and specs of a tried and proven dyno tested race pipe ...

Here's an interesting TT thread complete with some great pics ... where a guy makes his own pipe ...
