jason_s Posted October 11, 2005 Report Share Posted October 11, 2005 no "craks" in mine....just the whole car inside and out vibrating Link to comment Share on other sites More sharing options...
RedRobin Posted October 11, 2005 Author Report Share Posted October 11, 2005 That's defo a problem Jay but the experts will want to fix it for you so don't worry. Mine seems like just a sort of 'carbon dump' crakk almost like a backfire but nothing like as loud which is probably not a problem but just unexpected and not even often. Flaming quads would look pretty cool!! Let us know what the experts discover. Robin Link to comment Share on other sites More sharing options...
jason_s Posted October 11, 2005 Report Share Posted October 11, 2005 evening red. i think mine is just the turbo back, hopefully the resonator will sort it out. ps have alook at my new thread, id like your thoughts on it please "back to stealers" Link to comment Share on other sites More sharing options...
GTiMK5 Posted October 12, 2005 Report Share Posted October 12, 2005 And so it continues. If anyone is considering getting a Milltek, AMD are currently offering free fitting on all Millteks. Also if you purchase through West Tuning in Thruxton they will fit free of charge. This is not bad considering one of the other Milltek suppliers quoted me £90 + vat for fitting so pays to shop about. Link to comment Share on other sites More sharing options...

RedRobin Posted October 12, 2005 Author Report Share Posted October 12, 2005 Re "Crakk!!" sounds....I now reckon it's possibly excess fuel drop in manifold under certain conditions. Not a problem if so. Re Milltek loudness....The Turbo-back + Resonated is virtually exactly the same loudness as Cat-back + Non-Res. Turbo-back + Non-Res = Too LOUD!! for road use. I think Jay would agree. Link to comment Share on other sites More sharing options...

AlanH Posted October 13, 2005 Report Share Posted October 13, 2005 At this rate we'll all be driving a Mk6 GTi before we determine which, out of all the possible exhaust combinations/variants, are the quietest/loudest Link to comment Share on other sites More sharing options...
RedRobin Posted October 13, 2005 Author Report Share Posted October 13, 2005 Hi Alan - I think we have already established which are quietest/loudest as I listed 3 days ago. The only additional info to that might be that I have now established via Milltek that the Cat-back+Non-Resonated is the same loudness as the Turbo-back+Resonated system - They have 2 GTIs with each system fitted. If this is the longest thread it's probably all my fault! Amazing how interested people are in exhausts! Link to comment Share on other sites More sharing options...

RedRobin Posted October 14, 2005 Author Report Share Posted October 14, 2005 I know that this is even more Milltek info and also it will doubtless amuse everyone to learn that apparently Milltek are wondering if I'm one of their employees/salesmen that they didn't know about!! But, to further help people's decisions: Standard VW exhaust = 89 dB Milltek Cat-back + Resonated = 91 dB* (*Not tested) Cat-back + Non-Resonated = 93.8 dB Turbo-back + Resonated = 94.9 dB Turbo-back + Non-Resonated = 97.1 dB All the above, except marked*, were tested at half-metre away at 75% max revs. For Quads add 1 dB to each. Boy-racer exhausts are probably around 110-115 dB and some louder still and are also distorted rather than a true sweet sound (like Millteks - plug, plug ). I hope this helps anyone's decisions.

7MAT Posted October 14, 2005 Report Share Posted October 14, 2005 Great info RedRobin!! I will probably go for the Turbo back + Resonated @ 94.9dB (a nice mix of performance and sound). Unless I hear / read positive results of the new Supersprint Turbo back system. Not getting my car till probably March as I'm waiting for the Recaros to come available which should be soon as VW are now supply the GTI with supplement pages for the handbook which includes instructions for the new seats. 7MAT Link to comment Share on other sites More sharing options...
GTiMK5 Posted October 14, 2005 Report Share Posted October 14, 2005 Just had a quote from Elephant with cat back fitted and it is an extra £3.50 on my premium. Link to comment Share on other sites More sharing options...
AlanH Posted October 14, 2005 Report Share Posted October 14, 2005 That's good news! With my current insurer (Norwich Union) it only cost me an extra £18 with some discount.

GTiMK5 Posted October 14, 2005 Report Share Posted October 14, 2005 Cat Back - non res on order now. Free fitting on the 15th Nov at West Tuning, Thruxton. Would have been sooner but I am abroad until that date. Link to comment Share on other sites More sharing options...

GTiMK5 Posted October 14, 2005 Report Share Posted October 14, 2005 Sounds good to me Red, I am in the middle east at the moment but will be there on the 15th Nov all being well. Let us know how the 18th goes and what you think of the place. I have spoken with Ray West and he seems helpful and knows what he is talking about.

[/ QUOTE ]Red (or others) Have you any idea of the price difference from the Cat-Back to Turbo-back as it’s been mentioned that it could be at least another £150. Also seen mentioned that the Turbo-back is only useful if you are going to get the vehicle remapped in the future, which I really don’t have any plans to do, as it seems OK for me (at present). Is there a reason to stick to the Cat-back if you are not having the vehicle mapped or is it worth getting the Turbo-back for the extra 10bhp it gives (over the Cat-back)???

Cheers Mate [/ QUOTE ] ....Hi Celts I can give you answers to most of your questions because they exactly match the questions I have already asked both myself, Milltek, tuners and others. Firstly, the Turbo-back (or Hi-flow) component will probably cost approx £120-150 more plus any fitting costs if applicable (some suppliers fit for free) - I can't be specific on this answer. I too first thought that the Turbo-back was pointless unless you planned to re-map. However, now I know a little more about it and have had conversations with Milltek themselves (not sales people!), I would say that the Turbo-back makes much more efficient use of the GTI's standard FSI turbocharged engine than a Cat-back is able to. I have a Cat-back on mine (as everyone here knows only too well! - Did I mention Quads?!) and the extra 10 bhp is subtley noticeable and so is the throttle response. The Turbo-back gives 215-220 bhp, subtley increases throttle response, but importantly gives more torque and this also translates into the DSG system. If I had known more about the Turbo-back at the time of my buying the Cat-back, I would have bought the Turbo-back instead. This does not mean I am in the slightest disappointed in my Cat-back system - Far from it!! It's just that it's a more efficient and beneficial exploitation of the standard GTI power plant. Your question obliges me to say something I was planning to keep secret until after it was done: I am changing my Cat-back for a Turbo-back but only the 'front end' so I'll keep my Non-Resonated and Quad components and only swap Non-Res to Res if I consider it too loud but think this unlikely based on Milltek's latest dB tests they have shared with me. It would be pointless to re-map without modding the exhaust system but not vica-versa as you ask. Having asked others here I am confident that an increase in bhp which remains below 230ish does not put undue and longterm strain on the GTI's other standard components. Also tuning is not just about achieving the highest bhp number. It's about tailoring the car to best suit your needs and my needs are safety, durability and driveability on the road and not the track. I defo favour the tuners who tailor their work to the individual car and the owner's requirements on a rolling-road etc rather than albeit conveniently and cheaply turning up at your home with a laptop and a generic solution. West Tuning at Thruxton have been recommended to me, amongst others, by Milltek and I am visiting there next week just to discuss and learn more about tuning. It's a good excuse for a nice drive and I'll report what I think afterwards. Link to comment Share on other sites More sharing options...
