I picked up set pf DynaTech LT headers for my truck, and now I am wondering what to do about the Y pipe.
Will the headers install using the factory Y pipe? Would the factory Y pipe restrict the headers from making their max power? If so, how much restriction?
If I went with a DynaTech catted Y pipe would the power gained over the factory Y pipe be enough to validate spending the money for the DynaTech Y pipe?
Thanks for reading.

No stock ypipe won't fit and the only reason for buying their ypipe is to make instal simple. Fabricating the ypipe is a great option.

Factory y-pipe definitely will not work unless you cut it pretty much right at the 2-1 joint, and start fresh from there.

Don't forget you will need to have the rear O2s deleted via a custom tune.

IMO all cats are dumb.

They're not near as restrictive as they used to be, and my truck doesn't stink with exhaust.

F off. It was early. And in that case I completely agree

Would the straight Y pipe make me lose low end torque?
