It might sound raspy and it will definitely smell bad.

tibra1 · 09-10-2011, 02:59 AM

There are many that run catless DPs and stock exhaust..it kicks up the sound and performance..but for best results go full catless...FTW..im prolly gonna die sooner b/c of the fumes..but I love it..

az335idesi · 09-10-2011, 01:32 PM

i dont care about smell, only performance and somewhat of sound lol..like if im only getting 2hp out of 2nd cats but sounds like sh**, then i might as well slap them back on

I heard a car with ur catless dp and ae catless exhaust so basicaly the same thing as u would have but with ae mufflers instead of oem( but of coirse the ae is a full exhaust) and it sounded great im sure yours will sound good too.

I dont have any personal videos..but if you listen here..this is spot on what my setup sounds like..I cant decide which I like more the turbo spool up sound you hear w DPs...or the exhaust note out of the AEs..

az335idesi · 09-10-2011, 08:19 PM

but thats an after market exhaust =/..i want to hear the stock muffler completely catless.

Probably worth 8-10 whp at the higher boost levels and some weight reduction going fully catless vs dp+stock exhaust.

I am hell bent on not having to hear exhaust on my 8am commute upstate every day. If 10 whp beats me in a race, god bless you.

True.the I am def not one for an overbearing exhaust..dp w stock exhaust gives a nice compromise and opens the restriction on the turbos.

I think if you search on you tube you will def find some..

I have heard catless downpipes + secondary cat delete with stock mufflers and it sounds pretty good. But it actually droned a bit more than expected and wasn't that great. Then he switched to the BMW Performance Exhaust and it still drones but sounds way better under throttle.

shock2314 · 09-11-2011, 02:02 AM

hes mines, stock exhaust with AR dp, full catless

thebigragu99 · 09-11-2011, 02:05 AM

Add 2 vibrint resonators and you should be golden!!

dlbrooks18 · 09-11-2011, 02:20 AM

Edit: Actually I think in these vids they still have catted midpipes tho

If you hear my car from the inside, it is pleasantly quiet. I don't think the E92 has a resonator like the E90 has. On my 135i which did not have the resonator, the Dp+stock exhaust combo did drone somewhat but still not terrible by any means.

az335idesi · 09-11-2011, 02:27 PM

shock- i love it! its got a nice rasp, not and not a fart..sound great!

az335idesi · 09-11-2011, 04:06 PM

oh ya, shock: is that with res delete as well?

cedchung · 09-11-2011, 06:09 PM

don't do it. i went fully catless with the stock muffler on my car and it sounds really bad especially between 1500-2000rpm.

does anyone know if getting different mufflers will get rid of the raspiness?

shock2314 · 09-11-2011, 07:47 PM

I still got my stock mufflers, e92 doesn't have a resonator I believe.
