amuse STTI exhaust with HFC or FI long tube headers?
 

hey guys, soon ill be getting my amuse STTI exhaust, its on order and should be ready this month hopfully :happydance:

my questions are, what combo do you guys think i should go with for that set up, HFC's or FI long tube headers? im not looking to make it sound raspy, because from what i read the amuse has an exotic tone to it, so i wouldnt want to mess with that, i know the hfc will make the sound deeper, but will the FI make it raspy?

my second question is which set up will give me the better gains?

if i install the amuse first and either the HFC or FI long tube headers at a later stage, lets say for example after a couple of months, will that take away from the gains? does it make a difference if installed together at one time or seperatly ?

And last but not least which set up will sound the nicest, again from what i read, the amuse sounds amazing so i wouldnt want to mess with that by going with the wrong combo?

and a side note, just to make sure the FI long tube headers eliminte the HFC right?

Thanks guyz in advance.:hello:

Well

If you're looking for sound, then long tube is not ur taste, I say go with Fast intention resonated HFC.

so will the long tube make it raspy? what about performance wise which one is better?

yes the long tube will make it raspy.

I don't get it.. you're looking for performance wise or clean sound wise?

actually both, i mean if i get more performance from the FI but at the expense of my car sounding raspy then ill opt for the HFC, so you can say that im looking for clean sound, and wouldnt hurt to get some performance.

Lol As i said earlier, Go with Fast intention "Resonated" HFC.

Fast intention have an option to have 1 resonator and 1 HFC in 1 pipe. beat that :D

i will look into that, what are numbers i can expect with them?

i have no idea my friend, you might be looking for a Y pipe too since the amuse exhaust is not full catback..

you can get minimum of 30HP gains with Amuse catback + Y pipe + HFC.

test pipes!

no its a full catback singel pipe, but it is a full catback no need for y pipe, so u think hfc as well?

....okay, not sure who told you that, but, the amuse exhaust is NOT a full catback single pipe. it's a Y-pipe back exhaust only. i assume you bought the R1000 since you said single pipe? (correct me if i'm wrong.) but think about this.

it's only got one inlet, how do you connect the two exhaust pipes to your exhaust? with...er...a Y PIPE.

trust me on this one, i ran this system. you'll need an aftermarket Y-pipe as well. the stock y-pipe does this exhaust no justice at all. with that said, no need to run the amuse y-pipe or anything.

and fwiw go with the HFCs. it sounded pretty good when i had the exhaust.

this is it dual tip single pipe, its this was because the singel pipe is less restrictive sound wise, and test pipe out of the question maybe to raspy

:facepalm:

i ran this system, so i have personal experience with these exhausts. i guarantee, 100%, YOU WILL STILL BE USING A Y-PIPE. YOU DID NOT BUY A FULL CATBACK SYSTEM. two HFCs don't magically become one exhaust pipe without SOME metalwork conencting it!

the amuse exhaust compares only to the Y-pipe back section of the stock exhaust.

see the y-pipe all the way in front of the exhaust?

oh yes now i can see, so what y pipe did you run does it matter which one i use? what other mods did you combine with the amuse? and how does the system sound in real i know the videos dont do it justice

Oh phelan your car sounds great on that video b4 and after.. why did you sold that exhaust??

FI HFCs and the amuse y-pipe. It doesn't really matter which one you use as long as the piping is bigger than the stock Y-pipe. the stock one is so small it restricts a lot of flow, which means that single 3" pipe on the amuse exhaust does basically nothing. depends on your budget, there are plenty of options. tanabe is one that i know off the top of my head. others are mine's, fujitsubo, mcr...if you want a JDM part.

actually, you'll probably be mostly looking at jdm companies, as most american and other companies go for a full catback system with an x-pipe or different configuration. jdm ones for some reason still like the y-pipe.

other than that, the exhaust from what i remember sounded pretty good, no drone, you'll get used to the backpressure 'hiss' that all aftermarket exhausts make. The amuse systems seem to have a louder hiss than other ones in the cabin.

btw zuperman, if you want vids of hfcs + the exhaust (with stock y-pipe) go to my old review thread:

i didn't sell it. it's just off the car right now because it was damaging the fuel system. see my journal for an explanation, but i've got a temporary exhaust on until i can get the amuse exhaust back on. trust me, i really want my amuse exhaust back on the car.

you know what...just for fun i think later on i'm going to take a video of my current exhaust. it's hilariously loud.

phelan thanx for your input, so basically it will fit on the stock one but will be restricitive, do you feel the extra power with the amuse?

the exhaust will give you more power and torque. with that said, i can't really comment on the exhaust system alone, as i did a lot of mods at the same time.

thank you for your input phelan, you really helped me out

cant you see his dyno post? he got 15 HP and 9 Tq with stock Y pipe.. I can only imagine how many more power this exhaust will produce after installing any good after market Y pipe..

I would go with Motordyne resonated Y pipe;) *hint hint phelan*

i the motorgyne good? i was actually taking a look at the tanabe y pipe is that any good? whats the pricing on th motorgyne?

well..Motordyne Y pipe got several option with their Y pipe

either with how flow cats, Resonators or straight pipe.. Best Y pipe i ever seen..

i would go with resonated Y pipe just for sake of quietness.

how about price wise? the how flow cats one u mean it comes with hfc?

Yes!! it comes with HFC!!

check the prices of each one..click here

let me know if you have any question.

the 350Z Y pipe fits the 370Z? i read up on their manifold, but i didn't know if they had a Y pipe application yet.

yeh i was just wondering the same thing, it says that it fit 2009 models wonder if they mean the 370z?

Y pipe fits all model, from 2003 DE to 2011 VHR..

hope this answers ur question

thanks but i already have a y-pipe that cost me an arm and a leg to get, no need to get another one...:facepalm: :facepalm:

eh sorry but no need for that face palm icon,

I just never knew that you had a Y pipe. gratz on ur Y pipe anyways.

i think he has the amse y pipe, which is as good as the art amuse know for there top notch products, congrats bro on it

I received this week my Amuse STTI Exhaust + Jic-Magic Y-pipe + Test pipes.


you think is best high-flow cats?
