I anyone running any of these slipons on their DS.

WhiteBros E-Series ProMeg
Pro-Circuit T4
FMF PowerCore IV
FMF Titanium 4

I am very familiar with the e-series and the powercore iv on other machines, and I was curious how they fare. (and I don't care if it has disks). I'm a big guy (6'6" 255lbs) and really need to get rid of the stock ds's low end lag, and add a bit more punch to the midrange. I'm all set with a dynojet/K&N kit, and don't plan on modding the engine too much (bolt on's only). Any other suggestions for slipons are welocome as long as they have a removable USFS approved S/A available.

the HMF looks real good, but the S/A for it isn't USFS approved (not yet at least), which would cause me some headache some places I ride. Also my accountant (wife) won't let me go with a full system, so I'm stuck with the slip ons for now.

In my opinion the Titanium-4 is the way to go, saves tons of weigth and adds the same onto power, and is priced well at 247 with a stainless steel midpipe.

 

I'de have to agree with MadBaja819. The ProCircuit adds good power and saves weight at a price that will make your "accountant (wife)" happy. It sounds really good in my opinion, its a little loud but any pipe is going to be loud. Don't buy the quiet core for it, it does make it quieter but you loose any power you gained with the pipe.

 

i also agree with the procircuit t-4

 

I also have the Pro-Circuit T-4 and have had no problems with it. Don't be concerned about going the full pipe route, many have listed on here before that a full system is not necessary unless you go internal on the motor. The flow on the stock headpipe is good, and a slip on will help give you the punch on the bottom and save some weight too.

If you are looking for the best option, do a search for modified end caps. The talk is that they are as good as a slip on, but you still have the weight of the stock muffler... The upside is that you can save yourself some $$ and put it towards a Ron Woods CDI. With the K&N and a modified pipe or slip on you'll find yourself bumping the rev limiter if you ride aggressively (like the rest of us [img]i/expressions/face-icon-small-wink.gif[/img]).

Beyond that a 15T front sprocket or 41T or 43T rear sprocket will move your power to help the low end even more...

 

If you run where you need a spark arrester than I would go with the FMF powercore 4. I have one and it is a great slip-on. Tucks up nice and high, looks and quality are awesome, and performance is great.
