Exhaust
Not wanting to spend a ton of money on a new exhaust. Whats the downside to putting in a magnaflow performance muffler (maybe 4x9") and having it custom made using the stock tips? I cant imagine it would sound bad. other than it not looking OEM whats would be the issue with it?

IMO, Muffler delete, catless DP, I guess u can leave the resonator on because that's what I did (I was worried about it being too loud so I didn't mess with the resonator)... But honestly not really any drone at all and I daily drive my M235i. Anyway it sounds AMAZING and it's CHEAP!

i was thinking about going that route, but my wife really isn't a fan of loud cars. My last car - A4 3.2 had a full exhaust (which wasn't even that loud) and she hated it.
I would just like a little more growl, nothing crazy, which is why i don't want to spend $1000+ on a full system. |

Launch Control: Cold Start: Highway Pull (windows down, mic inside car, walls around car so sound is reflected back to car making it sound a lot louder):

As for muffler delete: There are cars sold stock without a muffler (The Alfa Romeo 4C and the Fiat 500 Abarth come to mind) that pass sound tests primarily through engine management software. BMWs aren't among those, though the N20/26 is a fairly quiet engine even without a muffler using the comfort mode ECU map because the revs stay low, and because sound tests are based on idle and moderate low-speed acceleration. It's definitely a viable option, though again: resale value, warranty issues, and (potentially, but not very probable) emissions could be affected.

Start with catless downpipes then you can decide how much louder you want your car to be,

Let's be frank here, since you're a commercial member: The N20/26 in the 228 has both an intake system and an exhaust system that are about as free-flowing as possible out of the factory. It's already common knowledge that aftermarket intakes do nothing power-wise, and any gains from an exhaust must come from removing the cat -- and even then the gains are minimal at barely more than 1 percent of stock power, coupled with a tune. So we're talking exclusively about changing sound through an exhaust. Where does sound come from? Primarily the muffler system from the midpipe back. All removing the cat would do is make whatever is inherent sound-wise (i.e., already present) louder. So why would you start with the cat and DP -- an illegal mod on road-legal cars -- when changing the sound is the goal of most? That's like amplifying a clean acoustic guitar tone when an electric guitar tone is what is wanted ... ?

these are all great options, but no one has answered the original question. What is the difference with all of these other catback systems that are $1000+ opposed to a custom mounted magnaflow muffler. I know you'd lose the valve control option, but is there any other reason that it wouldn't be the same thing as a $1000+ option for 1/4 the price?

I started with a DP and axle-back exhaust from AA and it was loud. Loved the throaty sound, but way too much for a cab. I have since re-installed the OEM DP and the sound is now what I want, still belches and has great run-overs.
The custom DP did add a "special" sound and I wish I would have tried that first with the oem muffler...curious. |
