Your right about it being loud, but you do get some good power gains with it. My friend has his 300 bored .20 and white bors. pipe and he said mine could prob. run with his. All mine has done to the motor is dg krome power, k&n filter, and jetted.

 

i have an rcm which works great... my pops has a chrome power full exhaust on his 400ex and it works great... its not really loud it is more of deep which i like...

 

well whats louder a krome or a rcm? alot louder? what is the sound level of an rcm compairable 2...like somthin that most ppl would no how loud it is...no what i mean? later - fanninator
