I've had my truck for three years and now im wanting to start doing more upgrades to it since I've got some extra money to play with and learn more about my truck. I just purchased some diffrent rims and tires yesterday my next thing I want to do is a 4 inch exhaust. I'm curious about keeping the muffler and what about the sensors and all that goes with it. I really would appreciate the feed back. Thanks

 

If you don't have an emissions inspection, I'd go straight pipe to the tip. No cat, no muffler, no resonator, no problem!

Oh yeah, don't piece it together like I did, 'go big or go home' is cheaper and easier.

 

theres no sensors on 6.0 exhaust systems. go with mbrp or silverline exhaust kits from turbo back. dont reuse the cat just use the performance muffler that comes witht he mbrp kit an your good. it sounds great an runs better

 

I run 4" turbo back into 6" stacks in the bed, no cat, no muffler. Ear's bleed when WOT.

 

Thanks guy's
