Been wanting to pull the trigger on a setup but this car is our somewhat-daily, not full on race car. So I want to keep the A/C unit, wiper fluid reservoir (can switch to narrow), ideally the cat as we have emissions in Colorado.. I'm ok with the intercooler replacing the crashbar though. I spoke with FI as that's what I was favoring most but it sounds like I would need to make some concessions as well as downpipe replacing the cat.

Is AAM the only one I should be considering at this point? Let me know what you have to give up for certain brands

 

You will really need to go with high flow cats. Maybe someone else will have more suggestions.

 

Check out the forced induction forum om the370z forum. Lots of info there.

 

cats (OEM or high flows) will burn up in the stock location. some folks have had cats welded in further downstream where the heat won't kill them so quickly.

my suggestion is to just go with testpipes or whatever downpipes are recommended for the turbo kit you're considering. you'll make more power, and it is possible to swap back in stock cats for emissions testing (its just time consuming / costly).

 

You could redo the flange from the stock three bolt to a v-band which would make it a lot easier to swap downpipes like that.
