catylitic converters

01stangV6 · July 6th, 2010, 06:59 PM

ok so i though i would update on how my first mods went. installed the bbk cai and just got my super 44 muffler in today and i love the boost in sound and acceleration. worth the money but before i got my muffler installed the guy said that i was missing my two main catylitic converters. now it got me a little woriried becuase he said my check engine light will never come off but i need to know how much those would run? there has been 3 owners of my car before i bought it. the first was a 77 year old man who bought it used in 2002 but he passed away last year so the car went to i believe his daughter in ohio. ( i can tell becuase of the rust underneath and small oxidation on my engine). anyway she drove it down to tn last year to her brother whom i purchased the car from. when i bought it he had all the receits of it being serviced and i dont know what or who took them off and why? sorry for the length.

is there a cliff notes so i dont have to read about the parts of your life that are useless to the question?

yes i just did one of those things in a sentence that you cant do

get some MIL eliminators or a tuner and u can remove the check engine light.

The dual converter assemblies are ~$1600 per side from Ford.

You can probably get the whole y-pipe with all 4 converters much cheaper than that from aftermarket suppliers. This is OK as long as you are not in Calif. In Calif. the converters have to be OEM.

The entire y-pipe with all 4 converters is ~$500 for a Walker part from Rockauto.

It's OK for non Calif. use.

most parts of TN can get away w/o cats because no emissions..so check to see if u can get away with it. if so never put cats back on and just get MIL eliminators or a handheld. have a great day and plz pm me if ur looking to hang out with a carp load of stangs in TN

01stangV6 · July 6th, 2010, 07:59 PM

yeah its just the 2 main ones and the guy let it slide becuase he installed it. and 6er w/a Vengance i will pm you in the future when i want to hang with a crap load of kick @SS stangs

I'm glad I read this thread. I am thinking about removing my catalytic converters, and just running straight pipes back to super 44s.

01stangV6 · July 6th, 2010, 09:34 PM

why would someone take them off? sound, power?

Some say you get more power, some say you don't I'll let others debate that, But it does make a drastic difference in the sound!

lol i dont know who would go through the trouble of taking them off and fabbing a new section of exhaust to take their place.

maybe it isnt dramatic, but less resistance to flow of air = more hp (as long as you keep enough back pressure)

Six Banger · July 6th, 2010, 09:53 PM

01stangv6 - have you considered these instead of going cat-less?

it does make a sound dif becuase i have heard stock sixers of the same year without my cai and muffler mine sounded better but now mine sounds even better.

01stangV6 · July 6th, 2010, 09:55 PM

no but the description says it only fits 06-07 4.0's ( v6 models) and mine obviously is not.

Ok, so with the question about power, Some say removing all four will leave you without enough back pressure, and some say that not having the back pressure will increase performance. I have been back and forth on removing the two I have left. Any one running with no cats care to give me there input?

You need back pressure for an engine to operate with maximum efficiency, but too much can hinder it. If you're running a straight pipe with no mufflers and no cats, you wont have enough back pressure and will loose power. If you have a good set of mufflers then you should be fine but make sure you don't get emission tested at inspections
