No, I tow a lot so Dan told me to stick with the 50mm helps maintain low end torque.

 

k and forgot to tell you i do have an aftermarket exhaust on it its not the greatest just a glass pack and ypipe but its nice and loud on the outside of the truck but not to loud on the inside i thought about putting a flowmaster 40 series on but i like the sound mine has now and dont know what the difference would be

Put a good quality exhaust on that truck and you will notice a difference. You are actually losing power with that glasspack. I run a Magna-flow exhaust and I really like it. Not to loud and not to free flowing. Remember these trucks still need back pressure to run properly.

so should i get a new cadilitic converter to or just a new muffler?

 

well, do you want or have to keep your cat?....if not then you can just ditch it....theres a couple of tricks to not have a CEL.....if youre gonna keep it, i would get a hiflo.....yours is prob gonna need replacin soon anyways

 

well how do you get around not having one and yea i would get a hiflo

 

I do not mean to sound rude but I do not think you are getting the point. High Flo does not always mean more HP. Usually high flow will hurt the HP and performance of the truck. Remember if you ask the Vendor(whoever you are trying to buy something from) they are going to tell you what you want to hear. There going to give you all of these numbers and make it sound great. Statistics can be made to say whatever they want them to say. That is what my Statistics teacher taught me. Keep in mind that they have there best interest in mind and not yours. They just want your money. Do a little research and I would suggest a regular cat with a good cat back system. I cannot tell you which exhaust to buy because everyone has there preference. Do the research and you will be happy with whatever you buy and remember you get what you pay for.

 

well thats why i'm on this because i dont know alot about these things but i have been wanting to get a flowmaster 40 series anyways so i might just keep everything how it is and just change the muffler
