Looking for 200 Cel cats for 3.0 SC modified.

 

so nobody has done this…how strange

 

I think most people interested in that mod have the 5.0L SC engine.
So not much interest in doing that on a 6 cylinder?

i have a velocity tune, larger lower pulley
450HP. The exhaust is now a problem due to restrictions therefore my ask. I know its not a shelf part however I thought someone may have made the mod on this site as there are a fair amount of 3.0 with the above mod (highly recommend -faster than my stock 4.2 09 XKR)
it does transform the 3.0 more so with AWD for traction
fyi) i have over 50k on this mod with zero issues
i do change the oil every 8k km which makes a big difference on the longevity of these engines.
i guess its time to find a good custom exhaust shop…

 

Generally the cheap ones are junk. At best they last only a few months, at worst the chunks from the failure can get sucked up to the combustion chamber. But I have not seen consensus here on a quality 200 cel cat that doesn't trip the CEL or I would have done the mod by now.

 

I did a custom downpipe set-up with GESi high flow CATS. I believe they were 300 cell CATS and have a write up on this forum about my impressions.
