Anyone running speed engineering headers and Y on a 99-07 4WD silverado? I have them on my 09 Tahoe and didnt have any issues but I know the older body style 4x4 had issues with some Y pipes.

Thanks

 

they are on my 06 4x4 silvy.
Slight fitment issues with cross over pipe barely touching front driveshaft.

Oval the pipe and it fits easy.

 

Have a set on my 04 z71. Only "issue" was slight contact between y-pipe and front driveshaft. Other than that everything fit and went in fairly easy

 

have the lt's but not the y on my 99. no fitment issues and i wouldn't see any occuring if i had gotten the y

 

I ordered them, they will be here next week. Thanks everyone.

 

Thank you for the business..

Installed them yesterday. The headers fit great, the Y pipe hit the front driveshaft and the transmission cross member and the flange that bolts to the stock exhaust would not line very well. I did not use the gaskets or clamps that came with them. Even with the issues they are still hard to beat for the money. I had problems with $2k headers and y before.
