I guess so:)

I made mine for my Cosmo and it wasn't too bad. I tried the whole cutting and welding thing but since I didn't have a welder I just took a long piece of exhaust pipe to the local car shop with a bender. I guesstimated the curve I needed and then had them crush bend it. I know crush bends aren't the greatest but it really isn't bent too bad. Then I had them put on some flanges over the pipe and then they mushroomed the ends so they wouldn't slip off. This way I could spin the flanges to match up with the cat and turbo.

The thing is with my Cosmo I already had a little DP shorty to attach my new one to but I think the T2 DP's have 3 bolts onto the turbo so it might be tougher.
