So due to the high cost of catback exhausts for our trucks and lack of power gains I decided to just run the round Borla XR1 3"in/3"out muffler in place of my stock muffler. I also purchased 5ft of 3" Borla stainless tubing and a new Borla exhaust tip that's 3" in and 4.25" out. How do I go about having this installed? I completely forgot that our exhaust is 2.75" after the muffler and that it goes up and over the axle... Did I buy the wrong stuff? Can an exhaust shop use what I have and re-run it over the axle? Will I have enough piping? I just am trying to make sure I have everything I need because the shops around me don't carry stainless tubing and I don't want that shitty aluminized that rots out.
