I am selling my Fast Intentions High flow cats for $300 (plus shipping cost if applicable) that I had I on my 2008 G35 Sedan. I switched them out for The Art test pipes and only used them for a year. These are a nice upgrade for HR motors. I was very happy with these, and I plan to go forced induction soon, so I needed something that was not resonated. I am not positive if these fit on the g37's. I would have to call FI and verify this.

 

will these fit coupes?

 

I called Fast Intentions today, and one of the reps told me these will fit on other cars as long it has an HR motor.

 

These will fit all G sedans 07+, G37 coupes, and 370z's. Sorry to be offtopic, but how do you like the ART pipes? Haven't seen too many guys run these in the HR yet.

GLWS btw!

 

I like em. My car sounds meaner and is a bit more responsive.

 

Do you have any video clips? Which exhaust did you pair them up with?

 

I have a 2.25 inch custom exhaust setup with X pipe and resonators. I'll post some clips in a few days.

 

I believe the only difference between an HR and Non-HR are just the flanges. Not 100% sure, If someone with a Non-HR wanted these they could just get the correct flanges welded on.

 

Thanks!

 

Did you sell?

 

How much shipped to 02148 and about many miles on them?

 

Hey I wanted to buy these within the next week or so, will they fit on my 05 g35x? If they do I'd like to buy

 

What is the HR motor? I have an 08x but apparently havent been out here enough to hear our cars referenced by HR.

 

This was on DE motor but they have not changed from DE to HR as far as I know, only final drive gearing on the inside may be different between coupe and sedan and between auto and manual.

 

Can you take more pictures? Looks like the left hfc can fit the oem O ring as gasket and the right one cannot?

This also won't fit the DE headers unless you have a HR engine or HR headers like me
