Okay, so I have read up on several posts where people have successfully removed their front two cats and used the gotts02 mod to fix their sensors. Or something like that. My 08 only has two cats. Any ideas on how I can remove them and fix the 02 sensors? I will be keeping my flow50 on there. I just want my truck to have better exhaust flow at highways speeds and maybe better mileage and yes I am aware of the emissions issue... but Im not going to worry about that

 

Have you thought about high flow cats?

To do the removal of you cats just cut them out and replace the void with pipe and do the Gotts o2 mod to the rear o2 sensers.

Disclaimer Note: its against federal law to run a vehicle originally equipped with cats to go with out them and if you live where there's a state inspection then they might find them missing.

 

Hey man, I'm pretty sure you'll get busted during the yearly emissions testing if you delete your cats.... unless you know a guy, in which case, hook a brother up!

Swap the stockers for some hi-flows if you want to mess with them at all. Henry's Muffler Shop down by Millbrook and Atlantic should be able to hook you up.

The best way is to tune for it!

 

My brother's brother-in-law has a guy he goes to in the Containment Area. I can get you the phone number That's why Im not too worried about it

 

I have thought about high-flow cats, I just don't know how much that runs. Im pretty low budget right now

 

I just priced the 94106 cats this morning...$50 each...pretty affordable

 

Cary?

I'm always on the look out for a good place since my front window tint is 18%...

Sweet! That's something I might consider.... But I would like to cut mine out first and see how it does.

yep Containment Area for Relocated Yankees (I really have nothing against northerners. I just find it funny how many there are in Cary, lol...

Yeah He'd probably check your windows too.... I know this place that will do UV film on your windshield and keep the heat down. I'll PM you this afternoon with the info

 

That flowmaster will sound better catless anyway, IMO.

 

Is that a direct fit for our '04-'08 f150s? And those are high-flow? I only have 2 cats anyways, so that would be about 120 out the door and I could install them myself it looks like. I think they clamp on?

 

I don't know if they're "hi-flow" per se, but it looks like the recommended applications are all larger engine, higher horsepower vehicles like supercharged Corvettes and Lightnings.

It would stand to reason that cat is designed to handle a higher volume of exhaust gas than our standard OEM replacements.

i just gotta get better mpgs... bottom line. Maybe i should ditch my hypertech and get an Edge. I dunno what I need to do. Lift it more, to reduce friction from the ground? lol
