i've been jacked haha thanks guys, the more input the better

 

I used to have Fast Intentions HFCs that I ran with Fast Intentions exhaust, then later with GReddy Spectrum Elite exhaust. It pretty aggressive with Fast Intentions and smoother and more subtle (w/ no rasp) with the GReddy.

 

1. I had Berk HFC with Fast Intentions CBE.. had 0 rasp, but had a little drone on the freeway. Sounded great otherwise.

2. Yes it is very possible to have rasp on aftermarket exhausts depending what material is used for the piping... I have a little bit of rasp with and with out HFC on my MXP exhaust.

 

I guess I really need to hear these in person to make my final decision. I like the way they pretty much all sound online and every exhaust has a unique tone. I suppose ill hit the meet on Wednesday and hope for a lot of people!

 

Just about every car with a V engine will always benefit from a true dual exhaust, whether is H pipe or X pipe. Both the H and X pipe do help the exhaust scavenging process much better than a Y pipe. And when it comes to exhaust flow, that's a good thing. Although performance gains of both the X and H are debatable, the sound advantages aren't. A properly designed Y pipe (something OEM doesn't care much about since cost is the #1 priority) can flow almost as good as a X or H pipe. But everything being equal, the X and H will always flow better than a Y pipe, and have a much better sound to boot. But like all exhausts, it must be designed properly or the whole point is moot.

I don't know much about the GTR but my guess is that maybe it's impossible to fit an X or H pipe on the RIGHT location. Otherwise I'm pretty sure the aftermarket would design a true dual for it.

 

^ on that note, i was under the impression a true dual was the best set up for our cars. how ever doing a little research there seems to be little difference between most of them true, x, y, h, in terms of power, a few horse at that.

also, i looked at the stillen, which has a model specifically designed to fit the X Coupe, it has a Y, no problem though, has anyone had experience with the stillen? i trust stillens numbers to an extent im just mainly curious about the sound. Numbers arent my main concern anyway.

and i checked out the Greddy Spectrum Elite, whats the deal with that? mid pipe back? or what ever?

and lastly i looked at the Gemini today, i actually spoke to someone about its fitment and i told him i have a Q300 on my X coupe now, he was astounded that it fit with out modification. I'm pretty sure the shop didnt do any modifying to the exhaust, i paid basic installation nothing special. I'm going to take some pics of the underside to send to him so he can see. He offered to hook me up with a Gemini if he can figure out if it fits from my pics cuz they didnt know haha

i'll be honest, as far as the look goes, i like polished or burnt tip appearance, they both look awesome. how ever i like the somewhat "stock" appearance of certain mufflers from the back, like the invidia or the stillen. no so much like the ark or the FI. no offense, i just think it looks funny. althought you definately know the cars modded from an exhaust like that

 

Post those pics on here while your at it, i want to see this since im considering getting one!

 

i def will post them as soon as i take them and if i get my new one in the next few weeks i'll have a q300 for sale if your interested lol i just dont recommend HFC's with it

 

Im not expert anymore but from what it seems, this thing is bolted right on no problem, anyone see any differently?










anyone think this looks modified? i do not

 

after all my thought and consideration i think ive decided to go with the stillen exhaust. I will probably be ordering it next week and i'll let you all know how it sounds when its done. Thanks for all the input everyone.

On a side note, i may be switching to an S at the end of the year, so i'll keep that ARK exhaust in mind for that!

 

not to be the downer to the, maybe 2 people watching this thread haha, but i decided to keep my invidia and just take the HFC's out. Its too much of an investment for me right now since i'm driving from NY to NC in a week and a half for 10 days. I'm gonna hold on to the cats and when i "hopefully" get my S at the end of this year beginning of next year, i'll slap those on and get a diff exhaust since everything fits the X. Thanks for all the input guys

 

here's a sound clip with kinetix HFCs. theres a bit of licenseplate rattle dont mistake that for rasp

YouTube - NEW INVIDIA EXHAUST with KINETIX HFC installed by AMPLIFIED MOTORSPORT

 

I did find a clip or two of it finally and i do like the sound but according to invidia, it doesnt fit the X. otherwise i would go for that one i think
