BMW N52 328i Muffler and Secondary Cat Delete

My 2011 E90 328i with muffler and secondary cat delete. Burbles a good bit especially when I downshift. It’s not too loud and sounds great. I definitely recommend it for anyone that’s looking for a fairly priced and good sounding exhaust mod.

Did this to mine but put a magnaflow muffler on too, ended up being a bit too toned down for my taste but sounds very similar to this

[@themysteriousdiamond4526]

Funny question but does it smell? I heard deleting secondary cats makes it smell bad

[@N54Kali]

I never noticed any difference in smell. It seemed the same as when it was stock

hey man, I wanna go this exact route with my e90 328i, but i was wondering of i would still pass emissions? Car Sounds amazing bro!

[@N54Kali]

Yeah you will. This setup doesn’t cause any lights on the dash or anything. However if you delete the primary cat (you’d have to do headers as well) you will get a check engine light so keep that in mind.

@@N54Kali Great man thanks! I'm still extremely hesitant to do it cause I live in NJ and our emissions laws are extremely similar to the ones in CA. The main one that worries me is the visual check cause if they see I'm without the second pair of cats I'm gonna be in deep shit lmfao. I was going to go with a Muffler and resonator delete but I feel that its just a little to raspy to me.

​@@deceiv-ed don't do it,when the inspector hear the noise and see that big empty space where de mufler belong you're toast!!!

[@Kevin-ep6kx]

Are those pops I hear??

[@N54Kali]

Yeah it burbles/pops a lot

[@shitnutzx2]

Nice thinking about doing this to mine
