Hello everyone I recently bought a 2007 525xi and was thinking of doing a muffler delete and a resonator delete as well but was told to just go for the muffler first and if needed then do the resonator as well. I wanted to know your suggestions and experience about how it sounds and feels after a muffler and resonator delete. I'm not familiar with a lot of the terms since this is my first car I want it to sound a little heavy I guess.

Thank you for your response.

 

Muffler delete only. The resonator delete on top of that creates a rediculous drone. After about 3 hours of doing my dual exhaust I ordered two 12" Vibrant bottle resonators...it was that bad.
