2003 4.6 Dual Exhaust Kit

[dhoisak]

Hi
I have 2003 EB 4.6L V8 4WD with Reload Leveling Suspension and Class III/IV hitch.. I have looked around the internet for a dual exhaust system to replace the stock system, but no luck. I guess this would have to be a custom bend and weld job with 2.5 to 3 inch tubing. What happens to the headers, cats and Oxygen sensors with a dual piped system?

i believe the third gens have 3 cats and theyre all up front so ur ok in that ballpark... if u get a dual exhaust system, it has to be custom... either u have to remove the spare tire and have it run that way, or it has to go below the differential (which sacrifices lots of ground clearance)... the way the IRS is set up makes it difficult to get duals in there with no problems... my suggestion is to just do a single outlet and change the exhaust tip... i put a flow 40 on mine with the stock tubing and put a magnaflow 3 1/2'' tip... of course u have a V8 and it will sound rediculously good so single or dual, its gunna have a nice rumble
