Im going to be ordering a TSP rumbler from Texas Speed. It says I need an adapter to run it on a LT1 but it doesnt show one anywhere on the website. Where can I get one? and why do I need one?

 

you need the "S" pipe to connect the ypipe to the exhaust. you have a single cat setup, which ends farther forward and off to the passenger side of where the dual cat setup ends.

i'm sure some of the vendors have the pipe, probably TSP. i know SLP use to sell it to mate their loudmouth to the older lt1s.

 

I was looking and did see that kit to put a Loudmouth on a LT1. Its the same thing isnt it.
