Car in the video sounds great.qny subventions to what exhaust you would use on a e92 328 with a m3 rear bumper. Want to do a m3 conversion and looking into what is the best exhaust to use for one.

If I had an american muscle car then I would do a muffler delete because it doesn't sound right on a bimmer. Back to the 2nd cats delete. The muffler gargle and pops more now. There is a tad bit of drone around 2K RPM but bearable. However I don't notice any drone when the car is in DS mode. As for loudness, maybe 5% louder. However the exhaust note changed. It has a warm throaty and gargle sound. Overall I'm very satisfied with this mod. Would I recommend this mod? Hell yeah! Here is my setup: afe magnum force intake, secondary cats delete, resonator delete, remus powersound (quad).

where did you get it done at??

Here is my MD with a lil extra work , the tips I got for $40 and all custom work and out the door $120.

Is this actually worth doing? W/o the resonator delete.

Been toying with the idea for awhile now.

just fyi,

I passed the smog with 2nd cat and resonator delete in January. The reading was excellent according to the technician.

oh my goodnes i've been looking for a post like this for days hahaha quick questions & stupid question, bay area smog test are the same as LA area right? planning on getting a PE & deleting the 2nd cat while they are down there.

also from reading this thread, I'm hearing a lot of low end torque is dropped if you delete the 2nd cats. would an AA tune fix this problem?
