Dave custom fabricates awesome top notch stuff.

The only problem I have with it is that it costs like twice as much to custom fabricate something verses mass-producing it. It is a Mercedes class pipe that is show car worthy in every way.

Nice pipe and welds. Dave Does do top notch work. It all depends on what you do with it...

I would love to See dave get some turbo manifolds made up though... Those would sell well with his attention to detail and quality of work...

I installed one on my buddies car. He loves it. Took out the crappy stock pipe and that thing really rips at the top end now.

I doesn't need it. You can check out my buddies that we installed if you want next time you cruise by Nate. Will have him come by.

Its probably due to the fact that shaking of the motor puts more stress on the DP if its mounted to the subframe.

It doesn't need it because it is a cat-delete pipe only.

You MUST use the front hanger support bracket if you run a cat. You can't add a cat to Dave's pipes without adding the front hanger bracket. Basically a cat is not going to ever be an option for this DP.

Makes sense...

And Oliver...will do. It'll be April before I get back...likely the dyno day (if I'm in town).:)

hmm. Not sure I get it. Dave ships a pipe with a CAT look-alike.

Look what the man in brown brought to my door today....

And it clearly doesnt have any supports. I think I'd much rather have the pipe firmly supported and the flex section longer. CAT, fake CAT, or no CAT.... These engines move around, and if you dont make provisions for that, the flex sections will tear more quickly.

The cat look-a-like is for the emissions inspectors. They need to see something that looks like a cat otherwise it is an immediate fail.

The DP could be mated up to the stock system with a bit of work but the biggest gains are to be had with a free flowing system.

If there are no emmisions tests in your area, run a straight pipe all the way back and enjoy the lower EGT's and the humm of the turbo :)

I know what the cat imposter is for. What I want to know is why no supports..... and why such a short flex.

I think the DP support was removed because it can be more detrimental to the life of the DP. The reasoning would be that this part would be added to already modded cars. More power results in greater movement of the engine and greater stress if the DP was connected to the chassis.

I don't know why the shorter flex joint was chosen, perhaps cost of manufacturing was a factor.

The wall thickness of the stainless tubing is quite thick with complete welds and I can see how it could support itself without hangers. I am pretty sure that the body hangers and supports will still be used. The only support removed should be on the DP.

After looking at the unit first hand, I have decided to get one for my ALH.

If you saw the materials used in the down pipe you would understand. It does not need supports and the flex is more than adequate. This a serious unit made to last a life time. Will probably outlast the damn car. You really get what you pay for and this is money well spent in my book. I installed one and it was really an awsome pipe.

The reason OEM has the support on the front subframe and the super long flex section comes down to quality of materials and manufacturing process'.

This downpipe WILL support a catalytic converter, no problem.
All our products come with the same quality of materials and workmanship that we put into our race parts, still have never had a failure.

No sense in comparing this downpipe to its stock counter part. Its a bit like comparing a pinto to a s600 MB.

I beg to differ... the reason for the front hanger bracket is to mechanically isolate the weight ballast of the heavy cat from the flex section. That front hanger bracket is a load bearing support member for the weight of the cat, nothing more, nothing less.

You mean the flex pipe that you use is short, stiff and rigid enough to support the weight of the cat.

Sure, thats the other half of the reason.

Pretty much. And there isn't anything wrong with that.

Man lurker do you even have a car to look at? There is a huge steel support just aft the coupler. That is the support there that holds most of the weight.

How could you not see this? I thought you were making your own pipes and stuff, you surely must know this? Or do you?

We have a similar set up on the Rally Car and on my own car that I built years ago. Have used it for over 130K miles and never had a failure or issue.

As for the cat, that is why he has coupler there, so you can either use a straight pipe, cat, or dummy cat as you wish.

Hi Oliver... let's see if we are even on the same page...

Here is a crude MSPaint drawing from my memory of a 99.5-05 A4 TDI DP, either VE or PD (PD has an O2 bung).



I suspect that you are talking about the Mid-(ship) Hanger Bracket and I am speaking of the Front Hanger Bracket.

If you remove the front hanger bracket the cat will weight load the flex section and the turbo exhaust flange. I'm not so worried about the turbo flange. Practically all flex joints are made in China these days and the one's Dave uses are probably no different. It is a fact of life that they are the main source for them these days. I personally choose not to add the cat's weight to the flex. If Dave has good results from doing it with his designs then I tip my hat to him for that. Let's get one thing straight, I never said Dave's design would or would not work. All I am saying is that I choose to follow the OEM design of supporting the weight of the cat on the OEM provided FRONT HANGER BRACKET AND THE MID HANGER BRACKET. That is why they put the Front Hanger Bracket there. If Dave doesn't need it, then that's cool by me.

If Dave offers diesel cats on his DP's then I stand corrected. I mistakenly thought he only offered cat-delete pipes.

A dummy cat does not come close to the weight of a real cat so it should not be considered a significant additional weight load that will be trying to swing around wildly every time you hit a pothole or take the car airborne Dukes of Hazard style.

Are we on the same page yet?

Thats one helluva nice looking DP!
Oliver, what setup does your friend have after the DP? How does it sound?

I might opt for one of these beauties instead of waiting in limbo for Lurker Mikes DP, I don't need or want a CAT.
