Miltek broken again...

just put it on a Dyno then.........

I'm surprised to see so many people complaining, I was always under the impression that milltek had a good reliable product.
I had a system fitted to my VR6 Golf for over a year before the car was sold, the sound was perfect and I had absolutely no problems at all.
in fact been looking at fitting a system to the M5, it was a toss up between the Milltek system and the Hayward & Scott but the Milltek was shading it. I may have to reconsider my decision.

My opinion - it`s a piece of crap.
I bought one of the early ones. It had some dodgy welds that needed grinding down to make it fit. There were no gaskets although this wasn`t a major issue but is not ideal. Then within just 12k miles (I think - I did report here originally) it became buzzy/rattly.
I understand they have good customer support which is good but are backing up a crap product (IMO).
And yes, the centre section on my car sat very low on a car with std suspension - it bottomed out a few times mostly in multistory car parks.
When I pay me money, I don`t like becoming a product tester for a company. I don`t mind if it`s just the odd problem but it seems like even the updated Milltek isn`t perfect either.

Std BMW exhaust all the way!!!!! Hell, the milltek gives ya 1hp (or whatever) but probably also increases drag also the way it hangs down.

Might work for that, but put an E30 M3 on a Dyno.

Oh yeah, it sounded wayyyyy better than the Miltek

There is a possibility that it might return to it's previous owner

I have dyno'd and mapped may cars which "straight through" and "un-restricted" exhaust systems. It appears that most do not work and infact actually loose power. Some however do work.

My SE had an Hayward and Scott system fitted whn I bought the car. The power was approx 160ish BHP. It jumped up 40 BHP when I fitted a genuine system WITH catalysts. This seems to be more to do with the "X" section. The Hayward and Scott doesn't have this, or it never on mine, and I understand the Scorpian doesn't either. The "Y" peice on the Miltek works simialr to the "X" section on a standard exhaust, so this is why the Miltek doesn't loose power, and maybe gains it? Who knows?

50mm all the way....

Id really like someone from Miltek to post on this thread. Doubt it will happen mind.

I dont thnk anybody feels its a poor system in terms of the gaining power. As I see it, theres 2 main issues.

1)Fitment (IMO just needs the pipe that comes from the centre box to have more of an angle before the rear box. And raise the centre box slightly)

2) Build Quality (Welds really)

Shame, as with a bit of work on those details would become standard fit for all E30's. Having said that, aren't the S14's buzzy characteristics quite harsh on stainless steel?

EDIT for Rezaq
Its something to do with the way the gases come down the pipe. IIRC NA send "pulses" whereas Forced Inductions send a fairly continuous flow. AFAIK NA cars require a certain amount of back pressure to help scavenge the gases in the most effective way. Whereas Turbo cars just need the largest diamter pipe you can find. If you get a chance do a Google for it.

If the BMW back box would be the same quality as the centre, there would be no need to buy anything different. Most of the back boxes I have seen/welded seem to rust where the pipes are going IN. Looks like the slight angle of the box collects all the condensation in the bottom corner. And the catalitic converters do really "help" in this case as well with very corrosive condensation.

Matt,

It might get more with a Milltek?????
