M235i

Avian · 06-10-2016, 09:38 AM

Hi All,

I've tried to search the forum for an answer but have come to no conclusion.

In short I'm just interested to see if anyone knows if the BMW M235i M Performance exhaust system has any effect on the power produced from the vehicle. I know there's obviously a change in sound but anything further than that?

Is there any change in horsepower or torques produced?

I highly doubt there is as it's just a back-box but maybe by some chance there might be. If there is, can someone direct me to the relevant information.

Thanks in advance

I was told 8 to 10 HP increase when I installed it on my 2014 235

Really?

Was this a BMW dealership that told you this or...?

I don't think the exhaust does anything other than sound really.

Nothing but sound.

If you replaced the midpipe/resonator, you would get an increase. Just the muffler gives no increase whatsoever.

Absolutely no hp increase.

If you take out the resonator and have the MPE, will it sound like pants? Drone and bad sound altogether?

Will also second. No power increase. Just sound. Glorious sound.

If it's just sound, might as well code in M2 active noise instead of m235i

I don't know the weights but it's lighter that's a plus.

Power comes when you go catless. If anything, the response of the throttle could of have improved with the M performance exhaust.

Catless OR catted. Price is the main difference between the two.

I just got the fabspeed sport cat and the gains were huge.

It's a pretty great product, couldn't be happier with it so far!

I can definitely see one in my future!

How difficult is it to install or remove one of the fab cated or no cat downpipes?
Anything need to be pushed aside to make the switch?

Had a shop install it...without access to a lift it would definitely be hard
