[SOLD]Fast Intentions Exhaust Carbon Fibre Mufflers,12" resonators

[nub]

 

 

This was taken off my 370Z and replaced with an Ark Grip... "Why!?" Do you ask....Well, genuinely because I wanted something a bit quieter and I was interested to see how the Helmholtz resonators changed the note. The Ark Grip is a bit quieter, however not by as much as I expected. I'd say say the FI is only about 10-20% louder, probably because the FI has much larger back boxes.

Also note that I have a motordyne ART decat pipes which makes any system louder. So if you fitted this with standard cat it would be significantly quieter. Nonetheless, this exhaust is not extremely loud, it's much quieter than the likes of motordyne shockwave etc but nor is it one of the quietest systems. I will post some videos later. I couldn't tell you the Ark sounds better or worse, it's a different note, a bit more higher pitched and pops and bangs a bit less bit I'm satisfied that I will keep it. My favourite CBE is actually motordyne shockwave. I would love to try one but after a week of early morning cod starts but the neighbours would band together and conspire to burn my car into flames or possibly a car bomb to take me out with it. Still, if one came up I'd have to buy it just to try it 😀

If you have any questions regarding the potential loudness if your particular system then feel free to ask and I'm happy to give my opinion. Regardless, even with the decat personally I don't think is mega loud, subjectively speaking. Even with my ART decat there is virtually no drone at 80-90mph.

 

Moving on, I would imagine this exhaust is very rare in the UK, it is also more expensive than entry level/budget systems, including the Ark Grip, which until a few months ago was £1,340 before the increase. I couldn't find any UK sites listing this but I did enquire and I was told you're looking at £1800+ to get one shipped over here. Remember that USD prices don't translate to the equivalent GBP value unfortunately. Perhaps even more depending on whether you wanted the polished finished mufflers or the +$300 optional extra carbon mufflers as this one has! They do look rather nice.

Build quality seems to be of a higher standard too, not that the Ark welds are bad or anything but I know these systems are very popular in the states and hand built to order which accounts for the high quality and reputation of the product.

 

The main benefit of this system is the reduced weight. I believe stillen and nearly all other aftermarket cat backs are heavier than stock, this offsets some of the bhp/tonne gains slightly obviously as you're gaining BHP but increasing lbs! if you're one of those OCD weight loss guys or perhaps you're a carbon freak then maybe this will be of interest. Fast Intentions website claims this is 16lbs lighter than stock. And it is generally around 20lbs lighter than other exhausts. See pic no. 5 below where it lists the Stillen catback ,which is no doubt a reputable company and quality product, yet according to the numbers it 24lbs heavier than this FI cat back, which a fair amount.

 

A few FI have sold on here over the years but they were the standard option, not with the carbon Mufflers

 

Performance wise, you can check what claims are made on the website but i would imagine its similar to others of the same diameter and design. I do think having less bends must be beneficial I.e stillen has proven gains but it has several 90 degree bends, as do the others with that design, but I won't pretend to be an expert; I don't know which is the best! The FI certainly looks like an unrestrictive free-flowing design. Either way you can expect 15-20bhp from this cat back, as with all the others.

 

I think it's overall in very good condition, there is a noticeable scratch mark at the rear of one of the carbon silencers which I had attempted to capture but I don't think it's a scrape, more likely someone was careless when storing it. It is located at the back underside so its not possible to see it even looking under the car. I've tried to capture it in the photo, but aside from that the only marks are very minor not worth mentioning. It's stainless steel so it functions as good as new and the flanges are still solid. But generally, as per pics, I believe it is in pretty good condition including the carbon, flanges and polished steel resonators.

I bought the car with 16k miles, it's now at 19k so it has done a maximum of 19k miles but that's assuming the previous owner fitted it straight after buying it from new. More than likely it has only been on the car for several thousand miles, at only 16k miles 2011 plate it must have been a weekender or unused for a while. I think the photos demonstrate it is in very good condition, especially the parts you can see.

 

I have a box ready for this to be posted. I purchased my low mileage Ark Grip last week for £1000, which may have been a bit overpriced but the used Z market is so small that being patient and/or trying to haggle can result in missing an opportunity. Unlike on my previous Type R forums, you're lucky if one Exhaust is advertised per month on here. As such, owners can demand higher prices especially on stainless steel stuff that doesn't really deteriorate or function less as it becomes older.

 

Being that my FI is more valuable than even the newer and more expensive Ark Grip, and far more exclusive, I'm going to list this exhaust at:

 

£970 DELIVERED or £950 COLLECTED from BN23 5RP, Eastbourne.

 

I cannot travel further out of town unfortunately.

 

If I've overpriced it or it proves to be unpopular then in time I will adjust the price accordingly. Payment by PayPal or bank transfer if preferred - not cash. I don't remember the rules regarding PayPal gift, but I have a good reputation on many forums having bought & sold stuff more valuable than this! Nathan (nrenz123) would hopefully vouch for me, even though I did nearly get away with stealing his Vauxhall Corsa 😂

 

But if a buyer is uncomfortable paying via gift or it's against the rules then we can arrange a price with a regular PayPal payment for the buyers protection.

 

No gaskets or bolts are provided unfortunately as I don't have them.

 

For peace of mind I will offer my own personal guarantee that should any legitimate and reasonable problems occur with the exhaust within 1 month of the sale, I will accept a return of the and offer a full refund. I can offer that in confidence because I know it's in perfect working order, only removed last week, stainless steel and it will continue to function for many more years unless you're vin diesel or one his

 

Once again:

 

£970 DELIVERED or £950 COLLECTED from BN23 5RP, Eastbourne.

 

These two photos of the single main scratch/mark that I feel I should mention, it genuinely won't be seen as it's far under the car. In the second photo it shows you how small it is. Any other marks are negligible.

 

 

 

 

 

 

 

 

This one ain't my car but shows what it looks like.

Those HFCs I sold you were good, in terms of build quality they were better than some others IMO, I've heard many Berks HFCs can fail cause the metallic core can perish, but that may be because they're a lot more common. Additionally they the FI HFC is 300 cell I believe, 200 should still pass emissions but not very easily and you'd need to get them heated up right before the test. If your mechanic is a friend or specialist then fine, but otherwise your typical MOT place may not be willing to entertain this idea, and without being heated up, a 200 cell might fail marginally. aside from this, unresonated HFC should all sound similar really unless they have a mini Helmholtz resonator on them too, and depending on the length of the core. But yeah, any HFC will open the sound up really nicely. With the FI cat back and HFC on it did sound good although a bit louder than I wanted, partly because there was a leak on a gasket which I didn't know about.

You can see now what I meant about the 370z market being very small and slow. it's not every week or even every month that a good HFC or CBE comes up for sale, even on the Facebook groups. Like my exhaust is up now, but after this is sold how long until another CBE appears? It could be a week, or it could be 2-3 months or more. And it may or may not be one you're looking for ! I still love still think I'd buy a motordyne shockwave knowing full well that I'd have to take it off and resell it 😀

 

As for this exhaust, the value is in the exclusivity and the looks (if you think carbon fibre looks better than polished/chrome steeI). I don't know how many more of these exist it the UK. It can't be many. and some in the US would say it out performs the entry level cat backs, but who knows .

 

If I get no interest in a few days then I'll happily reduce the price. It's worth what someone's willing to pay but I'm not that desperate for money to wait months for full asking price 😂q

Any offers? I can't see why nobody would want this, as opposed to a lesser quality system that's likely £1500 brand new.

 

Price drop again £880 including delivery

 

😊

In my experience it will go for close to your price but you need to not be in a rush and the right buyer will come along

[nub]

Yeah agreed. I guess a lot of people have not even heard of it and the scene is much smaller over here. I've got the receipt where the guy paid around $2300 for it. To me the design looks less restrictive that Ark Grip but I've not noticed any difference really and I don't know how those resonators affect performance. The FI was a bit louder but also deeper. Here's a comparison video, same setup just different exhausts.

Fast Intentions:

 

Both have Motordyne ART test pipes. I posted better videos at start of thread, the best drive by videos are outside the car and I haven't been able to really test the ark Grip in that way oh well.
