I am hearing Lsxtreme closed the doors. I have their headers. Has anyone tried another y-pipe that fits decent ?

 

pacesetters are good

 

The Pacesetter Ypipe is garbage. The only time I recommend it is when being used in conjunction with their headers because it bolts right up and there's no hassle.

The "best" way to go about this is doing a custom 3" Ypipe with a high velocity flowmaster merge.
