Nice exhaust. Did you do any research on replacing the cats? I have a G35X in MA as well. See you around

 

Most that I spoke to said there would be minimal gains if I did replace them, have you? I wonder what the gains would actually be?

 

I have heard that changing to HFC has more gain than updating the exhaust system. I am still doing researches on it now. Stillen told me that their HFC will fit, but the cat don't have the stock bracket attachments. So the cats are hanging by the headers and the exhaust pipes after them.

Most of the HFC out there are like that too. I am looking for the HFC that have the brackets on them, so the vibration won't damage the other exhaust components.

 

I want to get the 140093 setup for my G but I have an 06, 5AT, Sedan. Borla does not have an offering for this year. Any insight? Are there any fitting issues?

 

Should be no issues with the 5AT, my car is an X and that is what messed me up.

 

Crawford CATs come with the brackets.
