Anyone want anything fr ATP TURBO?

[Kor]

I am putting in an order from ATP today for a few accessories/fittings.

If anyone wants anything, we can split the shipping.

Post up, MSN me or whatever.

Order goes in before I go home from work. I will pay up front on my credit card, so if I trust you, you can pay me at the meet next week or whenever stuff gets here.

This is a rare opportunity, since basically no order is too small, as long as I know you.



Some things people might be interested in (other than turbos):

- Performance Downpipes
- Intercoolers, Intercooler Pipe Kits
- Blow off/ Diverter Valves
- Colored Silicone hoses, clamps

Kor, you vile temptress! How much does one of their 3" downpipes go for?

Downpipes are $249, you can see in the picture, it doesnt come with a cat, ATP sells those extra for $195. I dunno much about their downpipes, certainly not as complete as some of the other products out there.

You must admit it looks pretty similar to what you can get on ebay for like $90-$100:

ATP's cat also looks suspiciously like the magnaflow 3" cats that go for $60 on ebay.

However, there may be differences I don't know about... maybe Ryan would know he does read a lot of 'tex posts. Personally I would probably spend the $150 on ebay, if it don't fit, resell on ebay, worst case you are out the shipping. Much cheaper than $500 for some of the name-brand ones.

Make sure you get a 3" IMO.

Re: Anyone want anything fr ATP TURBO?

So I need a downpipe and a cat? I thought you use your existing catalytic converter? My down's syndrome might be the reason I don't understand this - I get confused easily.

Re: Anyone want anything fr ATP TURBO?

haha thanks kris.. from what i've read the ebay DPs work 100% so many people are buying them.. they fit, flow, and work perfectly.

Re: Anyone want anything fr ATP TURBO?

So all i would need is the DP, then? There are no other parts to buy?

I think you do need the cat, pretty sure the stock one is part of the stock downpipe. I don't know for sure. Someone confirm. IT could be pretty hard to mate a cat with 2" inputs and outputs to a 3" downpipe?

Anyway, as Ryan said, the ebay ones are getting good reviews... after all, a pipe is pretty much a pipe.

Re: Anyone want anything fr ATP TURBO?

Yes, here is what an aftermarket Downpipe looks like when it comes WITH a cat:



You can see, all one piece.

The ATP and eBay cats are two-piece. The straignt piece is BEFORE the cat, the bent piece is AFTER the cat. The reason it comes in two pieces is that you need to supply your own catalytic convertor.

You could maybe have the stock one put in, but I would say you want better flow than the stock cat anyway if you are bothering with this.

One mod I can suggest is that if you have an exhaust shop put this stuff in, get them to extend the 3" diameter as far back as possible, and put the reduction pipe in late, nearer to the rear axle. More 3" pipe is better, gives exhaust more time to cool off.

Re: Anyone want anything fr ATP TURBO?

So to summarize:

I would need (1) downpipe, (1) Cat pipe, and (1) Catalytic Converter ?

Then get it all installed at a reputable exhaust shop and ask them to extend the 3" pipe as far as possible.

How much would this all cost?

And yes, i realize that I have 1) hijacked your thread completely and 2) gotten everyone else to do the invstigatory work for me.

Re: Anyone want anything fr ATP TURBO?

Caveat...I know nothing...

but why go with a less restrictive downpipe only to follow it with a restrictive cat/exhaust?

[Kor]

Re: Anyone want anything fr ATP TURBO?

It is not good to have a more restrictive exhaust later, however, upgrading the downpipe alone does make some difference (apparently). I am guessing this is because the air loses some volume as it cools. The 20th AE also has a better cat-back exhaust (stock). The best case for HP is a whole new exhaust but this is not affordable for everyone...

Extending the 3" section may or may not be viable, this is something you might want to do later.

Yes, you need either a 1-piece downpipe that includes the cat, or a 2 piece downpipe and a cat.

I do not know what installation costs would be like. We could probably bolt up a 1-piece downpipe ourselves. On a 3-piece system, it may be trickier if we need to weld on any flanges. Hard to know until the product is in hand.

Okay, well, it sounds like you are not ordering from ATP, so if anyone else wants anything, please let me know. I am just ordering some fittings.

I'll take an ATP k03/k04 eliminator kit (GT2X) for transverse 1.8T's, please

That one would need to be paid up front

Re: Anyone want anything fr ATP TURBO?

I remember reading a facinating article by an exhaust designer, and he said that having a reverse cone (exhaust getting slightly narrower as it goes towards the tail pipes) is not always bad, as the restriction causes pressure changes and can actually accellerate the gasses to eject them faster than a giant pipe all the same length. Similar to a nozzle on a jet engine. Anyway it went over my head, but the point was that most exhaust are designed a lot better than you may think just by looking at the diameters.

There is something to be said for this "theory" - some people believe that as the exhaust becomes cooler, and so more dense, allowing the denser air to fill a larger volume creates a "plug" that has a huge total mass. As new exhaust is expelled it must fight against a larger mass. I am not sure if this is true or just gibberish.

Anyway, I do believe that having less restriction right against the turbine is a good thing. Even if all it does is move the restriction point away from the turbo, that cannot be bad.
