In the next week or so i'll be purchasing 3" buschur tbe.

my question is, how much would the install be? The downpipe needs to be cut and welded to the stock flange correct? and i don't have access to that kind of equipment; so ballpark, what am i looking at here?

 

There shouldn't be any welding necessary. All you actually need is a 12/14mm and some jacks/jackstands

 

The only thing that may need to be cut is the oem heatshield. You can cut/modify the stock heat sheild to accomodate the bigger downpipe. If you have an aftermarket heat shield, no cutting necessary
