ok, I have kakimoto exhaust with hi-tech y pipe (flex pipe deleted), and just put the xforce hfc last friday. The exhaust note is incredible sounds like a ferrari, but the drone issue is really annoying me when I'm going uphill or cruising at certain speed.
as for my current exhaust setup, do u guys reckon to weld two flex pipe on the y pipe or put resonator on the middle pipe to reduce the drone?
here is the setup b4 hfc

 

Once you've got drone, it's pretty difficult to get rid of unless you reverse the mod that caused it to begin with.

Adding flex joints won't help. A larger resonator in the midpipe might help.

More info on your exhaust please. Link to where you got it? Sound clips?

Is it this one?

OP's location is AUS, which I'm guessing is Australia, and I think the license plate says NSW, which I think stands for New South Whales, in Australia if I'm not mistaken, and they got easy access to Japanese or for us guys here "JDM" parts....Lucky for them huh, This is a very nice looking exhaust, and the HFC's I've never heard of, but once again it's probably off the Japanese market. Australia loves their Japanese cars, but good suggestion to add another resonator, I just hope that can be done without chopping this nice exhaust

 

i like to know if theres a sound clip also!
and i believe bulletproof has it for 1030$ , is it worth the price for that exhaust??

 

If you want to hear exhaust sound clips goto G35turbo.com it has what your lookin for. I think my current set up is probably a lot louder than anybody's. Borla header's, invidia test pipes, and hks Ti tru dual. drove thur a tunnel tonightand it sounds like a NSX race car

 

G35turbo doesnt have that exhaust system (kakimoto) this guy is the only guy on the board that probably has it , havent seen anyone else with this system

 

Yeah thats true. I was just seen if you wanted to hear some other exhaust cause i've never heard of that exhaust before tonight.

 

hah thanks man, i been on g35turbo a few times to hear those exhaust system, but this one looks pretty awesome

 

or other way change exhaust to some quiet one like fujisubo or nismo?
here is the link http://www.nengun.com/kakimoto-racing/regu-06-r where I got it from.
I will try to get some sound clips in the following days.

 

yeah man, I'm in AUS. NSW stands for New South Wales.
u r right. It's easy to get all the *** parts but not for our car, coz still not much ppl mod their V35.
For the high flow cat is made in local. It's popular here as hi-tech. They all make in good quality exhaust at reasonable price, but I was surprised how expensive were those high flow metal cats. It's about USD$660 rrp.

 

it happened to me also, i tried to search the spec. of kakimoto on this forum, but came out nothing. It was my friend lend me a *** car magazine untill I found out this is a well famous company in ***.
I love the quality on their exhaust, especially the titanium finish on the tips.

 

There is your problem.

OP, any chance you can record some vid/sound clips of your exhaust?

 

Oh ok. do you know what mag it was, cause i'm still wantin to see anything new from japan

 

Yeah i can do that. i'll get some friend's together this up coming weekend and record some vid's

 

It's called Hyper Rev, i'm not sure whether u can get it in the state, coz it's import from ***.
they have full article of our V35 which is whole book, everything from interior and exterior are all listed in detail.
