Well said. Yes that ;p its 100% subjective, some people even LIKE fart can sound. Fi was too high pitched compared to ark, in real life and in clips. No doubt fi is one of the better ones but i would hardly say best. You cant for a moment though say that a large part of fi choosers werent heavily influenced by popular opinion. I chose the ark without giving a **** about what ANYONE said and just went to listen to them in person. Dont take advice from people, you have to hear these in person. Or u might end up with something u didnt expect.

That percentage is grossly incorrect, as 99% of the forum will be in excess of 124,000 people, and FI to date has shipped under 1000 units.

Also, it's popular because it's the best exhaust offered for this car.

:stirthepot:

I think you win with custom! I know you said you have insane rasp. We'll I did too with LTH but after a fix, no more rasp and it's all custom done be me. You should really fix yours!!

I'd say it's one of the best. You can't get much better than FI. Have you even seen their build quality? :shakes head:

Nothing to fix brosef.

Exhaust rasp is about the least offensive noise my car makes... lmao.

Wow I'd kill myself if I thought rasp was a good thing. Might be the most ghetto, cheap, horrible sound a car could make. Rasp to me would be like people who say "you spent $30k plus on a car, do it right and don't cheap out." I'm not saying your header back is cheap but for a free fix it could be what its supposed to sound like.

LOL guess you should never buy and modify a Porsche then.

Well I have a fix but he don't want it. I'm sure there's a way for them too.

Voice59 10-16-2013 03:27 PM

I have the MXP catback and although it could use just a touch bit of a deeper tone..I like it a lot.

Streetlife 10-16-2013 03:41 PM

I have the Tanabe Medalion, Tanabe y-pipe also, couldn't be happier! Tanabe offered everything I was looking for including deep exotic sound, no drone or rasp,unique but elegant look, SUS304, and the perfect fitment! I've always been a JDM fanatic! It was fun deciding on the perfect exhaust for me though, it's not something i left up to anyone else! :tiphat:

:facepalm:

The rasp is just how the car sounds... You can't hear it over all the other noises the car makes inside the car and I don't give a rats *** what it sounds like outside the car... Why would I add weight and complexity to fix an issue that isn't an issue?

chii370 10-16-2013 09:43 PM

lol no..... its not "just how it sounds" there are plenty of exhaust setups that make zero rasp. my dts is just one example. do you know what rasp is actually CAUSED from? Im positive you dont. there pretty much isnt a car on the road thats generally modified often that i haven't seen at least ONE setup that made the car rasp like hell. Do some research on how an exhaust works. why bigger isnt always better, why "backpressure" is something a retarded noob says because they dont know wtf they are talking about. how taking TOO much restriction away is a bad thing. how exhaust scavenging works. its all physics. I can bet you my next car payment that you could even make a big burly V8 rasp with the wrong setup. I know this because ive seen it.

This same thing annoys the hell out of me like those that are absolutely convinced that turbo/SC builds HAVE to have 3in exhaust with no cats, or HFC...... its NOT THAT ******* SIMPLE to just make things bigger with less restriction. please do the research, not trying to be a **** but ive heard this a million times already and almost everyone who says it dont even know why. ive even been kind enough to give you a huge hint. velocity.

On a turbo setup, higher flow is always better. The turbo is a huge restriction, and anything you can do to get the gases out faster will lead to greater efficiency. The best turbo exhaust would be a dump tube out the side of the car like you see on purpose built race and drag cars.

Lol what? You don't care people make fun of you cause your car sounds like crap? Sounds like you went to walmart and picked up a CBE? Not to mention losing HP??! Lol ok dude, I'm sure you don't. Anding 5 pounds isn't so going to kill you and make a difference of you being you vs Michael Schumacher.

I'm only trying to help. I had more rasp then you I bet when I went LTH. Guess what? Easy fix and I don't look like a tool driving around with a raspy *** $36k car that a weed wacker sounds better than.

Couldn't of said it better myself!! I'll even bet a car payment he's losing HP for a very poor setup. Add 5 pounds of fix but gain some power from a proper exhaust with proper scavenging is sure worth it to me!

chii370 10-16-2013 10:08 PM

Ive seen plenty of cars ive had buddies build that fell into the DERP BIGGER MEANS BETTER retard mindset and went from 2.5 to 3 or even bigger. And then gained absolutely nothing on the dyno. There IS a point when its too much. and FI 370's arent exactly a popular choice as we all know, so metric a55tons of options are not available, nor have they been around for 10+ years for tuner experience. So its hard to say what that limit really is. But yeah, im sure at 8000 RPM with a tt setup pushing tons of HP WOULD benifit, but at any other time, it doesnt, especially NA cars. its not just about flow restriction, i wish people would get that **** out of their heads. its about FLOW VELOCITY. you can have MORE, LESS RESTRICTED exhaust through a 2.5 on a motor than a 3!!! OMG HOW you ask. well, allow me to give you a physics lesson. Exhaust comes out in pulses, not a constant stream of air. ahead of the pulse is a high pressure zone, behind is a low pressure zone. each pulse "pulls" the pulse behind it through the pipe. Now if you have pipes that are too big, the pulse will esentially use too much "energy" and start to slow down and instead curl in an outward motion toward the pipe walls. this does 2 things. causes turbulence, and causes a possitive pressure against pressure still exiting the engine, which can raise the pressure directly outside the exhaust valves. If this happens you can be robbed of power by less exhaust exiting the cylinders so less new air and fuel can enter or maf will be incorrect, and more effort to "push" the exhaust out the pipe. this also causes the infamous "rasp" everyone talks about. its NOT a noise the engine makes. Its caused by a drop in exhaust velocity somewhere along the pipe, which creates turbulence. this breaks up the nice individual exhaust tone "puffs" you hear and exits the back in a nasty sounding wheezing noise. havent you made the corrolation between setups that rasp, and the fact that MOST of them are the LEAST restrictive? or have LTH? or HFC or cat deletes? its not simply a "sound the engine makes" EVERY CAR can make that sound. start watching vids for aftermarket exhausts on other cars on youtube. like a tiberon or something. one setup will sound great, and the next will rasp like hell.
