034-EFI express 3" downpipe.Opinions?

[bertman]

Having been waiting for a long time for a custom 3" downpipe,I have been let down after being told that it was going to get made time and time again.
I have no choice now but to purchase one of the above,as I have no time to to take the car somewhere,due to new baby and work etc.
If anyone has used one of these above can they give me there opinion please.I am aware that they might need some "fettling"
Cheers

I had one in my car, it is a beautiful piece!



It fit perfect, since it is a stateside company, they output is usually to popular aftermarket exhaust setups here, but they are all in the same basic place, just the distance normally changes. It was a perfect fit for me.

My experience.

Mark of EFI is very good and helpful, the pipe arrived and was perfect / lovely looking.

On my '95 ABY Avant, when I fitted it, it fouled on the the rear of my cross member/outside curve of the downpipe, and also on the underneath of the CV heat shield top of the exhaust. It should be noted that the car has 034 street density mounts for engine and gearbox with Rusty's front snubber, and a single mass flywheel so the gearbox spacer is not used.

It is possible that with putting the car on a hoist and loosening the engine, gearbox mounts as well as the front snubber and then "manoeuvring the engine about" with tightening everything up using washers / spacers the rubbing issues could have been overcome, or alternatively the downpipe taken off and cut and bent and patched to get it to clear the crossmember and heat shield. ( I don't want to run it with out the CV heat shield and keep having to be concerned about the possibility of having to replace CV boots regularly. The car is a daily in slow city traffic).

At the same time as the downpipe was fitted a 3" "custom" system was fitted to the car, using only two boxes, which were not big enough, and the car was too loud, and together with the fouling downpipe, I took it all off and put back on the RS2 downpipe and the oem S2 system, the car was lovely and quiet / discrete, no loss of performance, so in essence I should have left on the RS2 downpipe and the oem system with cat bypass pipes, and just had a bung welded into the RS2 downpipe for my air/fuel ratio gauge.

One doesn't hear the I5 half as much, but the quietness all the time is much better, for me, than going around the place with a loud exhaust that I might like the sound of some of the time, but which everyone else thinks, his exhaust is broken on his old car, or "o another boy racer", in an Audi this time.

Using the cat bypass pipes from Ultimot.de is a good idea, and I'd be happy to suggest someone doing that. Very small bit of extra noise, and less choked top end, on the odd time one goes over 6k rpm.

My circumstances dictate I do the work on my drive, and can't weld, don't have all the time in the world with family and work, so had wanted a bolt on downpipe, as I don't know of anyone over here that could do me a one off s/s 3" downpipe that would look and be mint, and for me the idea of a bolt on 3" EFI downpipe didn't work out for me.

I could try the pipe on one of my urS6's, but it would involve more messing and expense with the oem exhaust system which is currently nice and quiet, so I'm not going to.

The above are just my own experiences.

Sorry the post is so long, but wanted to put my answer to Rob's query into context.

HTH.

Kind regards.

There is a 3" downpipe with S2 fitment. I run a tubular manifold from these guys, beautifully made. This one comes out about the same price as the EFIexpress one but the best thing is that you don't have to hassle about with customs as it is in sweden.

I have the full 3" system from 034, the downpipe is a good fit but the rest is not. Not enough clearance over rear driveshaft and it slightly touches the rear subframe. Also not too sure on the grade of stainless they use as my backbox and much of the rear section is pretty rusty
