today there are bunches of pipes to get for a 400ex.... right now i have a stock 400ex and i want to know based on opinion the best pipe for the 400ex.... and along with that should i go with the full system or slip on.... thanx (what i want in the pipe is added top end without the sacrafice of losing the low end because my 400ex has plenty of that but what i want more of is top end) thanx

 

i dont know much about this but anyof this stuff since i'm new to modding the fourwheelers. i have a Stroker SX1 pipe. its only a slip on but i'm sure Stroker makes a full system. www.strokerspeed.com it allows plenty of flow but yet again i'm new to mods on quads
