I have a 97 XLT 5.4 with 130k on it. I have finally fixed all of the coil and plug issues that we are all so familliar with. I would now like to tackle the exhaust. I have allready installed shorty headers last year when the stock manifolds went bad. I need some suggestions.
1. Cat back, sigle muffler (flowmaster) set up with dual pipes out the back?
2. Buy new high flow Cats, and do option 1?
3. Replace everything from the headers back? True dual exhaust?
What's the best bang for the buck? If I delete the rear cats, will that screw me for emissions tests? What did it cost you for your set up?
