best exhaust system!!!!!!!!!!!!for 400ex

[Sporttrax400ex]

I need to find an exhaust that is really loud and good for racing so it will be a great sound in the indoors track and the big outdoos???????????????????????

Hmmm.. by your signature, one would logically come by it that you already have a loud, racing exhaust system.

one would think so....

curtis is one of the loudest and one of the best with the most power.

i have a fatboy 4. its seems to be kind of loud. but like how it makes power i use it in xc racing.

I have a sparks and love it. If your motor is all stock try a TC racing slip on or the sparks x4

i wouldnt buy a x-4 even for a stock motor. sparks says the x-6 works just as well in most conditions on a stock motor and in the future if you wanted alot of engine mods you could just get them and already have a big bore pipe.
