i am looking at getting pacesetter long tubes with the ory pipe. i will be getting rid of the cats. Will i notice a huge difference in power? i like hp but mostly torque, how much should i expect to recieve at the wheels? When installing will i need to weld or should everything bolt up?

 

You should feel a better throttle response and get some good gains. I don't know much about installing them but I think you would need to weld the ORY to the headers.

 

Use the search tool to look up Pacesetter and you will find more than enough info!

 

If you do the ORY with it you should see ~15rwhp and ~20rwtq
