R55 Secondary Cat Delete Question
Originally I went with the ED (Exhaust Depot, Florida) 2.5 diameter from the downpipe back.
The feature I liked was the ED has a straight pipe and resonator to reduce noise with his system.
I have updated my system to use the resonator with the 09 JCW factory muffler and tips.
The original ED with resonator and muffler was becoming very loud.
System is now perfect. You could have someone make you a bolt-in/out or just take out the cat and be done.
Since the ED was 2.5, when I added the JCW we had to do a reducer on that section.
