Is it pointless to run headers on a stock Y pipe?

I know for LT's u cant run them with a stock Y. You gotta get an ORY from the company u buy ur headers from.

1nicet/a98

yah but as gains n sounds go. running LT'S rite into a stock Y is that pointless or no?

1FASTws6

U CANT. U NEED A NEW Y PIPE FOR LT HEADERS!!!! U CANNOT USE THE OLD ONE. i was told if u swap y pipes w/o changing headers the car gets louder and drinks more gas and u feel a bit of a power change. I dont know if its true or not

Mr. Luos

You need an aftermarket Y-Pipe with ANY longtube headers.

Mr. Luos

Shorties aren't worth much power on the LS1.
Stock manifolds are almost as good as shorties for flow.

Drop the money...get Pacesetter longtubes and y-pipe. Worth it in the long run.
