Still debating, but will probably go with Maddad more for the non-stainelss look, slightly louder from what I hear. I don't intend to change the muffler, so I want to get all the grunt I can out of the mids.

In a similar situation here and considering the maddad or the Berk for the mid pipe .... With intention to keep the exhaust stock.

Just that I had the Catless down pipe on my 1M now and worried that the maddad being too loud with the combination !

i had catless dp, berk mids and stock rear, and it was surprisingly tame. Not too loud when driving normal. When you go WOT, it really wakes up.

Yes, mids (MadDad) definitely worth doing. 247kW / 337HP (at rear wheels). I didn't dyno prior to doing the mids, but surprised at the numbers this car puts down... BMW certainly under-spec it on paper.

Actually BMW nailed the stock numbers. On a Mustang dyno most stock 1ms are coming back in the low to mid 290s which when divided by .85 (~15% driveline loss) comes right to 340s at the crank.

Yep.

337whp on a Dyno Dynamics is pretty good with just a catless mid-pipe!

It just seems underrated because quite a few cars are actually overrated... but I won't get into that here.

Now you guys have me stuck between Berk or Maddad!

I reluctantly let my fiance drive the 1m around on Saturday because I was using her truck to tow something and didn't feel like using my truck. Anyway, she managed to 'find' about a half dozen reasons to use the car throughout the day. I was out front most of the day washing another toy so got to hear her pulling up and driving away.

I have to say I am really impressed with the Berks. The sound when she pulled away was intoxicating. You don't realize when your driving the car yourself everyday just how good it sounds. I've had several neighbors tell me how great the car sounds too. It's not loud under normal throttle but definitely audible, deep and grumbly. At wide open throttle it does get louder and higher pitched at the top.

I've not heard the Maddads and I know people like those too but I couldn't be happier with the Berks.

What's the consensus Berk or Maddad? Performance seems to be very similar. From the vids I've heard, Maddad has an edge on sound. What's the price difference...$50?

Berks featured the dual 2.5 piping with resonators and into a single 3" Y ...

Any idea for Maddad ?

Looks the same both for Maddad and Berk.

Berk has two longer/skinny resonators side by side, Maddad has offset short/fat ones.

Pictures for comparison:

For my own personal edification and decision-making why not the N55 mid?

N55 mid is a great choice!

I just want something that is a bit larger diameter, louder, cooler to look at, etc.

Just had service done yesterday and tech informed SA that car had non-BMW oil filter and magnetic sump plug, clearly they were looking for issues. Nothing said re the MadDad's though due to their OEM look. The Berk's may be a bit to bling.

Please tell me they did not fault you for the filter and magnetic drain plug . . . . /endhijack.

I can't imagine how a properly fitted aftermarket filter or a magnetic drain plug could be used to void any portion of the warranty. Your dealer has issues.

Indeed, nor a Bosch oil filter as I believe Bosch make the BMW filter.
