Review on 🚀 Borla 40664 Turbo XL Universal Performance Muffler with Center/Offset Configuration by Eric Rios

Revainrating 5 out of 5

3rd gen 4runner 3.4L uses 40665 Borla

Got this for my 2000 4runner 3.4L and it's great. The only thing that annoyed me a little was realizing that our standard exhaust system is 2.5" in diameter, not 2.25" like this muffler. I still got it installed fine with a few adapters, but it would have been a lot easier with a 40665 Borla. sounds great, more ground clearance, weight savings. Can't complain for the $130 grand total, it's definitely better than spending $6-800 on a cat-back exhaust system.

Pros
  • This is great
Cons
  • Some bugs
