2nd Gen Non-Engine/Transmission Need help/info about HX40 4" downpipe on HX35

[JBlackwell]

I was looking at the back of my turbo today (bored) and just took a closer look at the exhaust elbow. Someone correct me if I am wrong, but I believe it is about 3 1/2". Well, I got to thinking about why everyone puts on a 4" exhaust without getting a bigger elbow. I have been searching on these boards for an answer and I guess I need to post this to get one.



I noticed that Piers has a HX40 4" downpipe adapter for the HX35. So I am taking it that I can buy this adapter along with a HX40 4" downpipe and clamp and it would take the place of the restrictive elbow on the back of the turbo???



I know it won't improve the performance of a stock truck like mine, but I imagine with 350+rwhp and the stock HX, it would help EGT's. I wonder what it would sound like then with it straight piped?? Another thing to note besides maybe better sound and maybe helping EGT's, you would already have the downpipe and clamp when you upgrade to a HX40 and then sell the adapter and get most of your money back. Just a thought.



Any opinions/thoughts?

I built an adapter to fit the back of my 14cm housing when i hybred an h2e turbo. I used the same adapter for my hot pipe to top turbo on my twin setup. That way i can change from a hx35 to a hx40 to try different combos.

Yes the adaptor allows you to run a 40 bandclamp downpipe to a HX35 turbo.



what a work of art
