what stainless steel cat or turbo back systems would folk recommend please? standard exit would be required. i see a full milltek system is something like over £1k, so i wondered what else people have experience of? a decent, deep, loud sound would be good...coming from the lovely sound of a scooby, i might be asking a bit much with that :grin:
-
Milltek & Blueflame are the choice of most on here. :happy2:
-
Miltek= :smiley:
Blueflame....... :grin: :drool:
I heard a blueflame at GTI inters and I was impressed...however if you want the OEM sound the miltek all day!
-
I have a number of hybrid Blue Flame cat back systems available at £795.00 for a short while longer :mad:
Kit includes the BCS downpipe and motor sport cat - we also supply a larger front silencer to take the noise down slightly - the overall sound balance is spot on over the stock pipe.
Have a listen here...

Trims are twin 90mm staggered

Nige....may i just say how much you deserve to be proded in the eye for posting that lovely sound up :signLOL: :drool:
That sounds amazing! Wich unlucky person had to hang out the boot to video it :rolleye:
-
good price and nice sound! :notworthy:

I have an MV sports TBE, really well made product and customer service was second to none. Think their website is MVpors-tuning. A guy called mike. I'm in essex and your more than welcome to come and hear it. I paid 900 for it and he threw in a panel filter
-
I have the APR RSC full 3" Turboback and wouldn't take any other. Due to pricing people on here tend to go for local product, but the RSC technology has no competition IMO. :happy2:
-
Is APR as good as people say? Only reason I ask is someone said the APR HPFP is totally redesigned, when I looked closer its the same hitachi that we all have, apart from an APR sticker on the side!
This isn't a dig more of a question to gain knowledge!

The RSC box removes the drone sound from inside the car whilst doing constant speeds on te motorway. This system has the sound of the for example non res Milltek, but not the noise inside the car. The RSC is wife approved :happy2:
If you get a chance, jump in a car with it fitted, a couple on here has it fitted :smiley:

Was that mine by any chance?

Thanks for the praise Jack - You know I won't rest until the world wants the BCS system - :jumpmove:
So Get your Pennies out Nige
The gift horse is nudging the gate open and about to make a run for it.
Coincidently I also designed the MV system which is the same as my BF system but with the hard edged trims.
Our downpipe and cat is modified from the stock BF version and I am installing a larger centre silencer to balance the appeal to a greater audience.

Funny enough, I would like smaller end pipes!! Nige, out of curostiy why has the MV got no back box when the milteks do!?

Well firstly smaller end pipes are not a problem - we can change the 90mm for twin 76mm if required for you.
With regard to the rear section - it's all about maximising the gas flow rate.
Here's an image of the Milltek rear on our MK 5 when we purchased it -
(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fh269%2Fnigeblueflame%2F_DSC1001.jpg&hash=7c0b9964e0e8b09387668fc3e263aca8b087a703)
As you can see the gasses are diverted all around the boot well and then into a baffled silencer - great for reducing sound - not so great for releasing pressure on the little KO3 after mapping.
We introduce a straight through silencer at the front of the system to negate the need for a rear transverse silencer at the back. This way the pipes can run fluidly without hindrance right from the turbo to the back of the car.

Very I'm formative! Thanks!! How much is just the rear section to make the pipes slightly smaller??

have you already got a Blue Flame pipe fitted -
If so to modify and fit new tails to you existing pipe would cost £50.00
BTW - here's a small crib sheet following some exhaust questions I did for Joe recently - it may help answer a few general exhaust queries... :happy2:
1) does the system bed in like most exhausts? - yes as the e-glass accoustic material settles the sound quality will improve
2) will the exhaust get louder or deep after a few 100 miles?- Without the cat in place the system can be deemed to be quite loud. Be aware that this may not necessarily be the case from one persons ears to another's ( remember the term - one man's meat is another man's murder) the key is balance - trying to hit the largest percentile of happy users, but generally after a few hundred miles the sound should have levelled itself out and settled to how it will finally be.
4) are the boxes in the middle and back silencers designed to create the sound? - the silencers are designed to create the power by allowing the gasses to pass unrestricted along the system - massively freeing up power. The stock system uses a process of sound elimination called "reflection" where the gasses bounce off baffle plates inside the silencers which collide and theoretically cancel themselves out. The downside to this efficient sound deadening technique is that the system produces excessive back pressure (bad news for the turbo- remember at 1.5 bar of boost the KO3 is running at 98% capacity). Our system uses a totally different process called the "absorption" process. This technique uses the same bore perforated tube as the system tube, which allows the sound to be absorbed into the silencer, which is filled with accoustic e - glass fibre. Whilst not as efficient at cancelling sound waves - it makes for the perfect solution when free flowing gasses are the priority - Oh and by the way it makes for a great sports tone that we are all familiar with in our petrolhead dna - as this is the way sports and racing cars were silenced back in the day. So to re cap the amount of silencing on a car using this principal is directly proportional to the CC's of noise deadening material employed within the system. Hence some people like the notion of a so called non resonated exhaust ( see my other pm re incorrect use of the term resonted ) Also the reason why Milltek systems are quiet is that they are not always free flowing - they use in certain configurations reflection baffles.
3) is the exhaust ment to be much louder inside of the car than outside? - As the sound waves are absorbed rather than reflected, the bass tones are amplified due to the bore diameter, in certain cases creating "cabin boom" this has to be avoided or driving will become a pain. The boom decreases with rev's as the frequency increases (pitch of the sound waves start to come closer together) so low revs wrong gear fully open plenum under load equals bad Karma for exhaust sound. The elimination of boom again is provided by using the correct amount of silencing. So less is not always more as there will always be a trade off - don't let anyone fool you into believing an exhaust running 3.00" primary tube diameters ( for power ) can remain pleasant to drive with one silencer - unless the car is constantly being driven at above 3000 rpm in any gear.
5) I'm guessing a stage 1 would change the sound all together? - yes the sound will increase with the extra boost slightly - this is amplified on the dsg, because the engine ecu induces a mis-fire on gear change, which is why you get the popping.
6) will the system backfire? - If yours is the dsg -plenty of popping, if manual not as much.
7) will the system flame - Sadly not, you would need a serious anti lag system to enable that and with 2wd you'd just sit there spinning the wheels (Imagine a bar of boost at idle and then dumping the clutch - plenty of flames and smoking tyres - but no motion
We are based in the North West and would love to re map the car using our custom GIAC software bud

I already have an MV TBE! had ot for about 18months! cant really fault it apart from it sticks out a little far IMHO!
Apart from that its great and very well made!
-
i must say blueflame sounds the abserloute nuts mate, sounds much much better than my mates miltek on his GTI !
:driver:
Joe.
-
got to have some "NOISE" from the exhaust...i don't have funds for Blueflame and Miltek is overpriced, imho. so what others are there? any Group N types anyone got?
-
How much is a blueflame then?
-
What is a "group N" exhaust? Heard it mentioned before!
-
Rally Group N regulation exhaust. had one many years ago on a mk2 CRX and it was spectacular. want something that has a few pops and bangs and has some bass to it. heard the miltek is quite quiet.
further up the thread is an offer for blueflames at £800...more than i will be allowed to spend on an exhaust by a long way!
-
Won't get much else for less unless you go used!
-
probably looking at used i reckon. so blueflame seems to be The One is it? Magnex? Scorpion? any others?

pipewerx tbe about £400.00, downpipe with sports cat about £460.00 or de-cat is only about £265.00 if you fancy failing your mot and chopping the cat back in once a year...
-
thanks for that...had a look at their site...will contact them when i am in a position. do you have personal experience of their products?
-
Niges system at BCS is the Nuts!
Got the TBE blueflame Decat, with the BCS custom down pipe! Sounds the nuts and you can really feel the proformance comparison over the Standard System.
+ Nice Price :grin:
Joe.
-

i paid £688 TBE Decat, with the two silencers. - Next day delivery
i ordered it Friday i think it came Monday. Perfect fit. sits spot on in the tail pipe gap.
Im a big fan of the look of the slightly bigger tailpipes sets the rear of the car off nicely.
Joe.

Thanks for that joe
Last of the hybrid systems available at the knock down price guy's
be quick ! :wink:
