Straight Pipes/ Muffler Deletes on a 128i?

I was just wondering if anyone has ever had straight pipes on their 128i. I am thinking about doing it, and am wondering what it would sound like. I don't know much about exhausts, but are a muffler delete and straight pipes the same thing? Please leave me your opinions! Thanks

i have a custom system that I bought from user Pushkin, look up his video's

its a straight pipe into a 135i muffler. Delicious sound, would not say its too loud, maybe just right. I love how the actuator that is plugged in the Golf tee mod still works and makes it tame at low rpm an HWY cruising

Thank you man, maybe rev it up to like 7k and hold it for about 30 seconds? Just kidding around 4-5 would be perfect!! Again, I appreciate it. I don't mind the cabin noise, I just would like to hear how it would sound from the outside.

If I wanted to do somewhat of the same setup as you, what would I have to do?

easiest is probably what i've stumbled upon translating German forums.
n55 midpipe & 135i stock muffler. All used. probably $300+ $200

Find an exhaust shop and have them cut the ends at the manifold/headers on n55 midpipe and weld something that will fit 128i diameter. Materials + labour

I think exhaust suppliers and other mfg of resonators have tubing ends that should fit 128i manifolds. I will have the measurement soon, just need to get to my stored sock exhaust to measure.

Most expensive is to get a 135i muffler and have a tuner custom build exhaust.
I think n54 muffler is quieter than n55 according to crude German translation

This makes me pretty excited for my headers, as they are both creating a real header setup, deleting a primary cat instead of a secondary cat, and will be heat coated.
