greddy dp replacement- ARTech or Begi?
 

Now that I'm committed to ridding myself of the stock downpipe... is there a good reason to go one way or another?

Begi offers theirs in either mild or stainless, not sure what ARTech offers though. Begi's is only available in 2.5, ARTech is available in a 3" but I don't think I'd really need a 3" dp at this point.

Can anyone comment on fitment of either?

Only other mods to the greddy kit will be FMIC, emanage blue, 360cc or so injectors, and full 2.5 exhaust. I'd like to shoot for around 200 reliable whp with this setup (I wouldn't be surprised if the manifold fails at some point though).

Thanks again all. Looking to get back into the turbo miata groove.

A friend of mine went with the Begi and it fit fine enough. I can't say I'm a fan of the way they connect the two pieces, but it seems to work.

cool, thanks for the response.had anyone had issues with the heater lines after? they seem to run real close....

I think most people bend the heater line so it's out of the way. You can also get wrap that protects hoses from heat. I'd put that on it as well.

I've had both. I say go with Artech and go with a 3".

I have the begi ss and wrapped it in heat wrap all the way down to the catalytic converter. No problems with fitment, and was a night and day difference from the DP that Greddy gives you. Much faster spool up.

I too agree with the above on how the two pipes are connected, but it does work.

Bat Inc sells -10 sizes fire sleeve that you can wrap your heater hoses with and it will probably do a better job than macrame silver foil cloth stuff.

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.

Go with the ARTech one. Curious as to why you think you don't "need a 3'' yet?"

I have the 2.5" Begi GReddy seperated gasses downpipe and it's very good, except for the stupid system they use to join the two sections together.
2.5" should be fine for your 200whp goals I would think?

I hate how my begi DP connects fom2 pieces with loooong bolt.

The 3 inch isnt about power, its about spool, if you dont need good spool now, maybe because drag car, but will need spool in future, maybe because drag car is turning to street car, then get the begi now..?

id go with 3 inch from artech, he makes stainless steel, could probably go with mild steel if you asked him it might be a little less but ss is the way to go. i have artech dp and i put reflective wrap around the heater lines and also a reflective pad thing on the brake reservoir.

more pieces (begi) could be more prone for leak and more annoying to install.

From the one begi dp that I have seen, I wasn't too impressed with the build quality. I would go with ARTech if he is available.

1000% for ARTech. He made my manifold and downpipe and I'll never use anything else.

Thanks guys... he's actually already on it for me :)

Post pix when you get it.

ditto...in for pics

I have a 2.5" ARTech 'Greddy' DP ... the craftsmanship is impeccable.

He is also a gentleman to do business with.

i'll be getting rid of my turbo tony DP pretty soon myself...need to sell it since I'll be getting an Artech I hope :D
