This is for a BMW z4, which IMO sounds better without mufflers than with any expensive exhaust system. The muffller delete vids i've seen the cars all still have tips though.... is the right way to do this to:

1. just cut out the mufflers and leave the tips hanging for appearance (this doesn't seem right at all for obvious reasons),

2. Cut out the mufflers and weld a piece of straight pipe

3. Just take off the entire catback and call it a day.

The third option sounds the best to me, as it's free and simple. Any pros and cons to just removing the catback and tossing it as opposed to replacing the muffler with a piece of welded in pipe? Keeping in mind I'd want this thing to be as freakin loud as possible without sounding like crap. I recently heard an S2k with the whole catback removed and it sounded sick, it kind of sold me on the idea for other cars unless there's some major downside I don't know about.

 

my stock exhaust is cut after the resonator - sounds really good IMO. without the resonator(as in just unbolting the whole catback), I'm pretty sure it would sound way too loud and people would think you're a d-bag. does teh Z4 catback have 1 res and 2 mufflers like the S?

 

Not sure, it's not for my Z4, I would assume it does. I don't have a good place to lift a car where I live (it's on dirt and in a big down slope) so I've never really gotten a good look at any exhaust, if you cut after the resonator do you need to add an extra hanger or something to keep it stable? I'm picturing the resonator and leftover pipe just bouncing around if not held properly, but I could be way off.

Loud is relative, I grew up on cammed muscle cars with fully open exhausts so everything seems quiet to me lol. I'll see how the Z4 system is set up though

 

no, there's a hanger on the S exh near the resonator

as you know, there's good loud, and there's ricer loud, lol
