Having only had my new car for 4 days I'm still grinning all the time. However, I am slightly disappointed with the exhaust note, and I'm thinking of getting AmD to fit a Milltek rear silencer to give the car a more aggressive sound. Having not heard a VX turbo with one fitted I'd be grateful for some feedback as to whether others who have one fitted have been pleased with the result? Is it worth having the full system fitted rather than just the rear silencer - can you notice the extra BHP? Twisle

[exjagman]

Yes very pleased and I got some nice comments from non VX drivers at a track day last weekend edited to add: and I've only got the back box

Yes, definitely - sounds awesome!

[turboman]

Yes, I have driven a few with the Miltek back box and or full system and it does give that slightly deeper sound without being too load, I never really noticed and extra power but then every VXT drives differently anyway, I did notice less lag though, but I put that down to no pre cat. Go for it, you know you want to. Wayne

The first thing I had done to my VXT was the full Miltek, and yes it makes a difference. In my case it gave 16 BHP increase and after about 500 miles the tone of the zuast tone deepens after the carbon deposits have laid. On a run, very quiet, but boot it . If you go the back box route, that will give you some of the sound , but the pre cat removal will give you the extra omphh you may crave Whichever route you go will be an improvement Bob

The full system is about £1000 , but how much has it cost to fit ?

Ring courtenays or AMD, I seem to remember about £300 including VAT

Certainly on my to buy list. Would love to hear one first. Need the throaty noise to match. Anyone in the North East have part or full Miltek system willing to demo?

[coltrane]

So would you say the Miltek is nearing TVR/360 sounding territory?

[Smiler]

Hmm.. doubt you'll get the TVR rumble... or the F1 crackle n rasp.. but suspt popping and farting are possible!!.. Christ if my friends could hear me!!

Sound file for ya - http://public.cranfi...video/piper.wmv

It's not a Milltek (the Milltek is a little more civilised and doesn't burble as much on the VXT), but you get an idea of what the VX engine sounds like with a little less silencing.

Never gonna get the sound of a V8 TVR or Ferrari from a 2 litre 4 cylinder I'm afraid...

Rather concerned by Jase MK's soundtrack Can someone reassure me that the Milltek rear silencer sounds more aggressive - I'm not expecting a TVR roar. Twisle

I've never heard the Milltek so could be wrong, i thought it was one of more conservative of all the sports exhausts in relation to sound. Edit; Shame Vauxhall never released a sports exhaust like their NA one.

I've got a full Milltek on my VXT. It is noticably louder than standard when accelerating. Whisper quiet on motorways, but as soon as you put your right foot down, you'd never mistake it for standard. It pops a little on over-run and burbles nicely when idling. It will never rival a V6 or V8 sound, but for me it is ideal, any louder and I'd be worried it sounded too Max Power. The NA sounds a little tinny when revving the engine with the car stationery. The turbo engine sounds a bit more meaty, Again apologies for the bad use of adjectives...

[Thorney]

TBH the only way you're going to be able to decide is to hear one. We've done sound files and they never sound right. VXT's sound completely different to NA's (more of a whooshing noise due to turbo) but new Millteks will be louder.

[chetwin]

I've got the full Milltek on my VXT and agree with all that garyk220 has said (although i don't get the the over-run popping). I also have a tuned TVR vixen (1970 vintage) with an exhaust made up by Tony Law. It has a throaty roar like the VXT under heavy acceleration, pops, bangs, and sounds like a race car. It's great for a blasting up and down the gearbox, but does become wearing when cruising at steady speed. It's also very hard to avoid drawing attention, something I prefer not to do when bombing round the local country lanes. I think the Milltek is a good compromise, sounds great when you want it to, yet off acceleration quiet enough to avoid unwanted attention, avoid horse stampedes etc.

Would the removal of the pre-cat and fitting a Miltek backbox be comparable with a full Miltek system. Both sound wise and Hp gains. Oh and cost wise.

Jury is out on that. I beleive the full system as all you are doing is moving the pressure further down the system, however the precat is most restrictive part.

[amrit]

Thorney, you mentioned "new" millteks? I might have missed something but are they producing a new zhorst?

[Thorney]

VXT/VXR exhaust - no change - dead happy with it NA exhaust - quite a few complaints that it wasn't loud enough. Whilst VXT system settled down to the exact 94db limit we wanted the NA has never got any louder than 87db (about the same as my M3) so there is room to get more noise from it to satisfy peoples desires. There is no more power from it as that was already pretty good, just a little louder with the same tone. In production now, should be available for delivery in 3 weeks time
