IM ABOUT TO PURCHASE A SLIPON EXHAUST FOR MY 07 DS650X.IT CAME DOWN TO A BIG GUN EVOX OR A PRO CIRCUIT T4.WHAT WOULD YOU GUYS GO WITH?IM LEANING TOWARDS THE T4 BUT YOUR OPINIONS MIGHT CHANGE MY MIND.WHATS BETTER ALL AROUND?I DONT HAVE ENOUGH $ FOR A FULL SYSTEM.THANKS IN ADVANCE

 

I have not any of them but I think the HMF is more popular for a good priced slip on.

 

i have 2 ds 650 1 has big gun full exheast kit and the other has just slip t4 on i really love the sound of the big gun definetly make people know your there as performance i havent ridin a stock ds but i would think the pipes should do the same or at least close to each other unless you get the full headers and mufflers

 

Save your money and simply buy the Power Tip from ebay. It replaces the stock exhaust cap and will flow nearly as well as the big gun kit for hundreds less. It makes a big difference!
