Hey guys I'm pulling the trigger on long tubes and true duals on my 05 5.4L

Was just wondering a couple of things first:

Will these:

Work without trigger the o2 sensor since it says without cats?

Also After the longtubes should i delete the rear cats or use highflows?

Planning on going with the x-pipe into 3 inch tubing...not sure on the mufflers...any suggestions??

I'm gonna finish it off with banks tips

 

Without cats means your getting headers without cats. Youd need to weld in a set of highflows. Or order the set that comes with cats. No cats will trip a code.

 

Also for true duels keep it all 2.5 (or 2.25) mandrel bent. Then dealers choice for tips.

Read the exhaust guide that is stickied.

As far as mufflers most will recommend magnapacks or borla (i like borlas personally) check youtube and pick what sounds best.

 

The highflows have the o2 port in them?

 

Either have bungs welded in after or get magnaflow 94136 has it built in. 94106 should be the other one without the bung built in.

 

Ok I would get obx with cats but it says supercharged only...

 

Thats for the lightning and harley models keep lookin around they have them for your truck
