Reddit mentions of Vibrant 1331 3.5" Round Stainless Steel Dual Tip

I did a muffler delete with vibrant 3.5-inch dual tips.

I made a couple mistakes on this one that I should mention... they are not regrets as much as things i would have liked in hindsight to have thought about.

• Had I to do it all over again while removing the mufflers would save me a lot of weight, I would have left them on and had cut them open and welded straight pipe inside of them. they would have mounted in the stock locations using the stock hardware, but... would give that muffler delete sound.
  
• The vibrant tips i chose just barely fit in the diffuser openings and the installer had to work on it a while to get them straight and not hit the sides... this required additional attachment points and such. (see my previous statement) Had I chosen the next smaller size down for the outlets, they would have been framed better in the diffuser ports AND there would have been less labor/effort
  
• I had the exhaust installed by a performance shop and not a muffler shop. just think, guys who work on exhaust all day vs guys who take their time to do a very clean specific job. I thought I wanted the latter, but I really should have chosen the former.
  
  All this aside, I think that the muffler delete is the best E39 mod you can do. I think people that ride behind me on BMW club drives may have a differing opinion, but on the whole... (preparation H feels good) It was well worth it.
  
  EDIT - I skipped over the part where you were cash poor. I was kind of task-driven to answer the question. Agreeing with others here, you may want to reconsider putting your money into a car when you should shore up your life a bit first.
