I was wondering why I do not hear much about BANKS products in the TDR. I admit I am new to the TDR and do not use this site much but after renewing my subscription I don't ever hear much about BANKS. My goal is to build a solid 600 tow rig for my 5th wheel and equipment trailers. Thus far I have a six gun tuner with PDA and have had my transmission rebuilt by the local guru's,good for about 800hp. So far so good! I also changed the intercooler to a steel tanker from the factory plastic. I have a K&N air intake kit also. Was pondering the next move and a 4 inch exaust sounds right for my 2005. Were these good choices and what is next, the goal is 600hp rock solid, not for the kid within.
