RE: MBRP 4 inch cat back or 5 inch turbo back?
I did mine while my in-laws were here.
I figured, heck, I'm already aggravated why not go put the exhaust on the truck.....
Only to be surprised that it was much easier than I thought it would be.
Don't even think about removing it in one piece, you'll never get it out.
Just hack it right in front of the muffler and remove the rear section. Then you can work on the cat with the excess weight removed.
Seriously, it's pretty simple.
If you wanna have it welded, then yeah, you may need a shop if you don't weld, but most of them come with clamps and mount to the stock hangers.
Give Mike a holler, I'm sure he can take care of ya.
