i m looking to buy hfc for my 2009 g37 awd sedan

i saw classified and saw Fast intention Non-resonated Hfc that used for coupe

is this possible to install in my sedan??

also how much labor i have to pay to swap cats??

 

Non resonated will add rasp, but with all other oem exhaust parts intact it shouldn't be too bad. If you plan to add a catback exhaust you might consider resonated HFCs as the rasp will be amplified quite a bit.

The coupe HFCs will fit but the piping is a bit larger for the coupes IIRC.

Might also consider resonated test pipes if you aren't idling in traffic often, as the raw fuel smell can get excessive there.

 

Are coupe and sedan OEM cats the same part number? Sorry, sort of off topic

 

Yep and shares with 370z.

 

Even while you're idling in traffic, if you put the AC system on re-circulation mode instead of pulling air from outside, you won't get the fuel fumes. Hopefully other people around you are doing the same though, lol

 

thankyou guys so much !! i think i will go for Muffler delete first and Hfc , Intake way

 

Muff Delete with HFC Non res may be a tad too loud. I personally love my setup of Berk Non res HFC and Ark Grip CBE. You can check the exhaust thread for how ti sounds on the highway or cold starts.

If you're going with muff delete and res HFC I'm sure it would be a medium drone followed by a few loud revs and then back to normal. I personally broke in my CBE and then got HFC once i was satisfied with the exhaust note output on a daily basis.

 

Thankyou for information !! i think resonated hfc and muffler delete gonna be match good

 

coupe is 2.5", sedan is 2.25" but they will bolt up to the sedan no problem

 

That's the default but FI can make it 2.5 upon request for sedans.

 

if you buy that used fi hfc, make sure you get it fixed first.
