I think I remember seeing this a couple years back that someone made a 2.5in downpipe or something of that general size for the Greddy turbo kit for the 99-00 Si. If this is true, who on the board makes them? Also, what is the cost and all that jazz? If no one knows what the hell I am talking then my bad Thanks in advance!

 

i make them. well now i do. just got the stuff last week. and im able to produce a 2.5 or 3" after the elbow for 165 shipped.

You can make some ****** coin from that.. Nice work man, nice work

 

KTeller.com has them

 

stock greddy downpipes really are a joke. this is a great product to be able to make!

 

Yea, I swear it is the same diameter that the wifes 03 Si had on its stock exhaust. Tiny as hell. So if I am running stock boost and an Apexi n1 WITHOUT a cat would 2.5 be cool? I would thin that 3in would be overkill at that low of a PSI, but hell I could be wrong.

 

Still, the cast iron pipe is still there. i havent seen anyone able to make a larger downpipe without it

 

The elbow part sucks, but I've been running 15psi on my 2.5-3" flared downpipe without any spiking or anything like that. Greddy Profec b spec II controlling boost. It was a really good investment upgrading that pipe...the 18g has some crazy spool when the exhaust is opened up.

 

i can make one. but you wont be able to keep AC. and you pretty much either gotta do 2 inch off the turbo and then flare to 2.5 . without AC a lot can be done but kinda defeats the purpose of the whole greddy set up right ?


the Kteller one is made for D series kits. totally different. diffrent lengths and diffrent bolt pattern.

 

I already have AC removed from my former turbo set-up. THe people who assembled my motor did a **** *** job. Sleeves sunk and the pistons were distorted. Engine sounded like a TDI Golf from day one. I plan on putting this on a stock motor with a headgasket and some headstuds, and thats it for the Si. It will remain the daily driver. If you can make a full 2.5in or hell even a 3in DP for me from the turbo itself to the cat that would be absolutely perfect. In fact that is what I would want.

 

I'd like to figure out a way to divide the housing and do an atmosphere dump with the wastegate. Might help control the boost spikes that some people are seeing. Help out the high boost greddy people a little bit.
