• Eurotuner before and after dyno of the BMW Performance Exhaust for the M3 - Gains of less than 2 horsepower

      BMW launched their own performance parts division not too long ago. Why? To make money, why else. But, these are supposed to be performance parts first and foremost. The performance part seems to be lacking as the BMW Performance Exhaust on this E92 M3 did not even gain two horsepower at the wheels. That is not a typo. Neither is the price at $4374 plus tax and installation. The worst horsepower per dollar performance modification in M3 history? Probably.

      If you intend to buy an exhaust for the E9X M3 and want an actual performance gain, we can suggest many other options for far less than 4 g's. We are thinking of a word BMW should use in conjunction with this exhaust. Let's just say "Performance" is definitely not that word.

        Nothing, they are in more than one area.

        Car is currently bone stock. It's an 09 e90 M3 w/DCT - let me know if you are interested and we can talk. I think there are a few photos in the forum garage - nothing special but will give you an idea of condition.

        Cheers!

        whoa - that's odd... Sticky, I noticed I commented between his two quotes - could be the issue.

        Yep, that is the issue. I'll clean it up.

        Many have to learn that a louder exhaust is not necessarily a more powerful exhaust.Most even quiet exhausts today are free flowing. But if you cruise the boards, most will spend over a grand or two because the exhaust sounds kewl.

        Part of the experience is the sound however a performance exhaust should also focus on... performance.

        If I have anything to do with this exhaust set up it will be powerful and refined sounding. Can't stand the NASCAR sound on so many of these aftermarket pieces. The S65 should be made to sound like an F1 car - take advantage of the high reving motor. Click here to enlarge

        Hey Jake, hope all is well... Did you want to have a chat? Very interested in seeing what we can do here - I am itching for a good NA system, just not sure what to get. Would love to be a guinea pig - don't have baselines, but am pretty confident my car is strong. :-)

        Cheers.

        Why is everyone so surprised here?

        Did you really think anyone can actually get more power with ANY rear exhaust?

        If anyone says they can they are talking completely crap.

        You buy this Performance exhaust for the weight loss and the sound.

        I bet a whole load of people have been told by sales orientated tuners that rear exhausts can add +10hp!! LOL

        I don't think anyone is surprised but more along the lines of for the money you can do a WHOLE LOT better.

        So why is everyone discussing it?

        Anyone with half a brain knows that the BMW rear exhaust is a very free flowing system and the gain shown here is to be expected.

        You are paying for an INCONEL exhaust.

        Simply to point out to people that there are greater values to be had and not to buy into a name brand. It might surprise you how many people simply have no clue.
