I agree. Get the 40's series or you are gone to wish you would have.

 

My 40s are not loud at all in the truck, but sound great outside. So I agree to go with 40s. The 50s are not as loud.

 

Same here go with the 40's.

 

yeah...after putting the flowmasters on my truck i definatly say go with the flows!!
