Can I use the downpipe from my 4" MBRP exhaust for the HTB2 turbo or do I have to get a new downpipe?

No, the stock turbo has a 3" outlet, the MBRP goes from 3" to 4" about 4" down the pipe. I ordered a 4" downpipe from High Tech Turbos, it was spendy though (180.00). I guess a guy could cut off the 3" piece and add a piece of 4", only problem being you would need a 4' coupler for the turbo.

HTB2 uses an HX40 dp.

Yep. Make sure you get the right vband clamp. They make two different ones in 4", for some stupid reason. The one I have leaks a little bit so it must be the other width I need.

WHen I bought my HTB2 from HTT, I also got their 4" downpipe (HX40). Fit excellent, came with the clamp.

anyone who's switched turbos have an old HX-40 DP they want to part with??

I had to buy one too. It is at home awaiting my return...
