need exhaust advice

[jmwilso2]

Hi everyone. I'm almost finished with all the mods I want on my truck. All I have left to do is decide on an exhaust system, then I can send my info to Bill for my custom tunes. I have decided on Dynatech headers going into true duals with Borla mufflers and tips. What I cannot decide is whether to spend the extra 650 bucks on the entire Dynatech engine back setup with their high flow cats and x pipe or to keep my stock cats and just buy the x pipe seperate. I started into this project with the interest of saving some gas but as per ususal I am getting caried away a little, its too late to stop now though or I wont be happy with the final product and will end up changing it later, its just how I'm wired. I'd appreciate any advise or personal experience anyone can relate to me.

Thanks

Joe
