Mike:
Thanks for the feedback.

Another thing, PAINTRACER quotes: "You will lose your heat unless you want to fab a small u-pipe from your stock headers to your heat ducting."
And tar6day quotes: "They come straight off the turbo."

How do you lose your heat function if these test pipe is connected off the turbos?

tar6day

The test pipe has no impact on the in-car heating. I run heat in my car. The heat produced by the header is pre-turbo. The connection is post-turbo.

What he said.

IamSMC

Thx tars6day. That's what I thought.

PAINTRACER as you quoted: "You will lose your heat unless you want to fab a small u-pipe from your stock headers to your heat ducting."
Please explain.

What is it that comes off the CATs?

What is it that comes off the CATs?

That would be a muffler by-pass. Test pipes eliminate the CAT's + mufflers.

I know that part! Have them on the car now. I meant the red heater hose looking things that connect the outlet from the headers to the CAT paipes. I've looked but can't find any pix. I'm out of town so I can't take any myself.

Header heat might be enough for cool climates (i.e. 40-50 at the lowest) but not for cold climates? I certainly noticed the lack of heat when I had a couple of the oval hoses on the cats loose and it was 35 F outside.

Here is a pic I pulled from the archives of a members engine.

Ah, that would explain PAINTRACER's quote.

Looks like an easy fab

Mike: Sounds like a good idea?
