Does anyone have SCP high flow cats on their Mark VIII? How hard were they to install? I need to replace my stock cats and was thinking about these. Also if you have some other brand of high flow cats please chime in here.
 
ive heard of poeple putting on hiflow on...but one thing is the driver side cat is welded to the exhaust manifold....sum like me did on my other mark gutted the cats ...whats wrong w/ the ones you got on now
 
How hard is it to get the driver side cat off? I have a feeling that my cats are slightly clogged and SCP is having a sale on their high flow cats...

not hard might be kinda hard but if you find the right welder it will be easy. lift the car up tomorow and have a look @ it
 
Putting any cat on our car, unless you have headers on is a bit of work. I am not sure if you can get to the drivers side without removing the whole exhaust manifold because the cat is part of the exhaust manifold. Also, the diameter of the pipe from the factory is smaller than what SCP offers, so there will be even more work. You may just want to gut the cats and be done with it for now.....until you get headers....if you plan on that. :Beer
