greddy dp replacement- ARTech or Begi?
#21
I'm thinking to go the same way. I am actually just now installing my Greddy kit and I have a FM 2.5" turbo exhaust. Currently I'm stuck because the aftermarket dp I have is 2.5" but it won't fit up to the 1.8L FM cat I have.
What size dp did you go for? Does it make any sense to get a 3" dp if you have a 2.5" exhaust?
What type of CAT do you run to fit up to a 3" dp?

If you're not planning on upgrading any time soon, I wouldn't. I believe to see any performance, exhaust has to be opened from the tip back. Opening it up and then restricting it doesn't help. I could be wrong though.

I'm getting a 2.5 setup to go with my ebay tsudo exhaust. I'm having an exhaust shop weld in a 2.5 pipe where the first resonator is so that it's 2.5 the whole way through.
I sent him a 2.5 cat which he's going to weld in place to meet up with the rest of the exhaust. I think he quoted a 7 week turnaround, he just notified me that my parts should be ready soon.

I'm bolting my old 2.5" exhaust to my 3" dp since I plan on upgrading eventually. I'm not sure I'd want to run that abrupt transition long term.
The same flange will work for a 2.5" and 3", it's just a bigger hole.
He quoted me 6 weeks, and he says that's what he tells everyone just to be safe.

Well after going back and forth on how to make a 3" DP work with my 2.5" cat and exhaust, I decided to bite the bullet and go all the way to getting a full 3" DP, cat, and exhaust from ARTech.
He has a lot of work on his hands so in the mean time I'm having him modify my 1.6 FM cat to a 2.5" inlet so I can use my 2.5" system for now. If I get a chance to dyno that before I switch to the 3" set up, I'll post some numbers.

Beg to differ. Fire sleeve is meant to impart fire resistance to lines carrying combustibles. It offers resistance to conductive heat transfer. In addition, the silicone rubber coating dissipates the heat of a fire by ablating. That said, it offers almost no resistance to radiative heat transfer.
If you want to make parts that are near the turbo and downpipe live a while, you've got to fight off the radiation (look at your turbo in the dark after a hard run and you'll see what I mean). The "macrame silver foil cloth stuff" is the right tool for that job.

California sucks for doing fun things to your car! If they truly just want clean air then everything should be based on what comes out of the tailpipe and don't worry about what I have under the hood. (I'm sure a million people have said this.) Done ranting.

It doesn't actually look like the wrap they show on the website. It is basically a tube with orange silicone around a braded soft fiberglass sock.
In the end my braded hose is no where near the manifold so I didn't use the Firesleeve. However, I was thinking it would be good to put over the heater hoses that run so close to the DP. I could see why the thin foil could be good to protect them by reflecting back the heat but it seams like this Firesleeve could act like a silicon oven mitt and insolate the hoses from the extra heat?
It's pretty expensive so I'll return it if it isn't going to help protect the hoses from external heat.
