Stock Y-Pipe size and Idea

[Joshwaa]

Wondering what the stock pipe size is on the y pipe that goes under the 8-speed. I was thinking about wrapping the pipe under the 8-speed to reduce the heat directly under the plastic pan. I know it is kinda flattened on top but I was gonna try to rap it from the round part before and after the pan. So what size? Also any thoughts on weather this is a good Idea or not. I already have the Lava Wrap so why not give it a go.

So I climbed under and measured it. 2.5" diameter. I will have the clamps tomorrow. Once installed I will report back if it makes any difference in tranny temps.

I dont think it will make a significant difference. Air is actually a great insulator and when you are rolling down the road there is no time for the pan to get hot.

Yea highway probably would not do much. However I drive in morning traffic where most of the time I am not moving. The 8-speed at least for me seems to get hot when your just sitting. Cooler when it is moving that's where I got the idea.

 

[hemihustlin]

Yeah traffic sucks. I see why you would want to try it out.

Yea notice my gas mileage in my sig. Too much stop and go city driving.

Should be 2.25 not sure how dramatic the difference will be but on a buddy's truck I put new pipe across there and we wrapped his and on my old 06 I built a full stainless insulated with koawool for it, but the new pipes were closer to the pan.

Before wrap.


After wrap.


Will report back on temps soon.

Links broken for me.

Links broken for me.

Try again should be fixed.

Looks good.

So from the limited in town driving I have done so far it has dropped the temps by around 10-12deg.
