exhaust for 97 taurus sho

[svoorh91]

i want to get my sho road worthy but i need cats and exhaust system. im buying maganflow cats but does anyone know where i can buy a cat back system? i keep googling it but its either universal or not for sho

Are you replacing the cats or the entire y-pipe? AdvanceAuto sells the Magnaflow y-pipe with cats...if you use coupon SP28 price drops to $335 and you get $25 coupon for future purchases.

I have not been able to find a cat-back either. Only option I am aware of is a custom bent system.

Just find a local exhaust shop and have them make you one. Should be about $300-$400 out-the-door depending on what you pick for mufflers and tips.

im buying the magnaflow assembly along with the flex pipe and the rear cat. awhile back my friend rebuilt the engine and the day he got it registered and insured someone jacked up the car and the stole the cats

strict emissions in NJ??

I'd like to cut out my back cat altogether. I certainly wouldn't replace it if I were redoing the system.
I think it passes w/o it anyway.

without the 3rd cat id fail inspection for emissions

In many states and provinces, you will fail your inspection if you do not have all three cats installed and operating correctly.

Is your car on Craig'sList?

What is the diameter of exhaust pipe going into the mufflers? 2.0?

 

[svoorh91]

no it isnt on craigslist and i believe its 2.25 if im not mistaken

 

[SHOZ123]

2.25" is the normal replacement size mufflers but IIRC the OEM pipes are down under 2" on the stock **** inlet.

No you wouldn't. OTOH, there is a midrange torque drop with the 3rd cat out.

Depends entirely on where you are getting the inspection, Ron. In places that do not test for emissions levels, or do but also check for original installed equipment presence, you will in fact fail the emissions inspection if the third cat has been removed. I have been to places that could care less and others where they will not even bother to check the emissions if a piece of the original configuration is missing, they just fail you immediately.

Do they have some kind of lookup to see what the original configuration is?

I doubt it. They know to look for two cats in the y-pipe on virtually every car made.

 

[kevinspann]

Right, so my thinking is that they won't notice the third cat or the resonator being gone if there is a nice section of straight pipe from the flex pipe back to take their place.

 

[RonPorter]

Plus, it's beyond the O2s, anyway. Never really got an explanation of why they did it, as they have the air pump for cold-starts. Just know that a coupla folks reinstalled the 3rd cat, and noticed the torque they lost.

They only look under the car when you cross the border:theyareontome:......
