Sick of the drone

135Hoser · 03-26-2013, 04:03 PM

So I've got AR resonated kitty free downpipes, factory mid pipes/resonator/cat and then a BMW performance exhaust, not dinan like my sig says.

I get a ton of drone/rattle/vibration in the exhaust system and I would very much like for this to go away.

I like the style of the factory exhaust with the flapper system. I do not want a loud exhaust all the time, like when I'm cruising, etc. I just want it to bark when I floor it.

Is there a preferred exhaust for a setup like this?

Berk midpipes really smoothed the tone out on my car, the OE midpipes are pretty junk IMO. The Berk’s will add some volume though, they’re def. louder than the OE N54 mids, and you’d be going full catless so there is the increased smell and possible smoke to consider.

BMWPE only.

I have catless DPs with stock midpipes/axleback. No drone, but obviously it's very quiet. Maybe aftermarket midpipe with stock axle back would be a nice combo?

I have this same setup. Its pretty quiet with no drone on the highway.

Is staying catless a requirement? I haven't got a ton of knowledge of other systems, but I've got my stock N55 DPs / mids and the Maddad Street Series axle-back. It's obnoxious at cold start-up (I like, wife doesn't). When it's warm and below 3000 rpm, it's pleasant (louder than stock, nice gurgle, no drone), but above 3000 rpm, it really starts to sound great (fairly loud, higher-pitch, still no drone!).

Cheers,
Bryan

I love my setup, catless downpipes, catless midpipes, stock axle back.

Has a nice raspy growl when you get on it, but super stealth when you're not.

berk mids completely got rid of my drone...i had n55 mids with resonator delete and it droned like crazy at 3k rpms...never bothered me, but it is muchhhh quieter in all of the rev range...

Double check to see if the exhaust is touching anything and causing the vibration. I have downpipes to a full straight exhaust and dont even get drone
