Best Exhaust Combo with Catless Headers? - BMW 3-Series (E90 E92) Forum

D-Raw · 01-01-2013, 06:44 PM

So after doing some research I've realized that with catless headers, many exhaust systems become really really raspy.

My question is for someone who has catless headers, what exhaust are you using and if you could post some sound videos. I'm looking for the least "Rice/rasp/civic" sounding exhaust.

from what i have heard, you definitely want a resonator or an X-pipe in there. from the videos ive heard, that seems to make the difference between the raspy cars and the decent sounding ones

Stock exhaust + Headers + secondary cat delete. Originally I was going to do a full cat back, but the sound it currently has is exactly what I wanted to begin with (quiet unless pushed). Im not changing it now.

Check the 2nd page of the MMW Headers-Teaser thread...

MMW headers + BMW PE (w/ secondaries intact)

It's not bad at all for normal driving under 3.5k but if you drive it aggressively I would suggest putting in a resonator.

Yeah bmw PE seems too raspy for me, anyone else with catless headers and an exhaust combo that works?

add a res back into that combo and it should be good.

A stright through bullet muffler may help too. They barely reduce sound and barely impede airflow.

maybe a res + bullet muffler

No one else has purchased gavins MWW Catless headers?

I'm sure someone has found the perfect catless headers and exhaust combo

I just want to bump this again, I wanna see if more people got the catless headers with an exhaust that's not raspy. Again I have the pe exhaust with catless headers and past 5k it is too raspy

I also have a PE w/ the MMW headers. I wanted a louder sounding PE, and that's what I got.

Yeah that combo is to raspy at high end for me
