Macht Schnell Test Pipes Installed!! (dyno/video)

Well, here's my latest mod and I'm pretty darn excited about it!

Got Macht Schnell Test Pipes!

I've been waiting for these to come out for a while now. Sure, there's a few full x-pipes on the market already but I feel they are ridiculously priced and I'm not sure they provide any added value. Plus I wanted something not outrageously loud.

It's clear to me now that those pipes are the best of both worlds. They're much cheaper than a full x-pipe + you get to keep the rest of your OE pipe. Secondaries and resonators stay intact, which means no smell and reasonable sound levels. Perfect!



OE vs OE + MS



Full pipe



10/10 fitment! Flanges line up perfectly, O2 bungs are positioned perfectly











A peak inside the stock headers



Now on to the results

We did a handful of before and after dyno runs. The last "before" and the last 'after' were the strongest runs (car keeps making power!). Below is the strongest "before" overlaid with the strongest "after":



<- me when I saw this

At this point I couldn't wait to drive the car! The gains are super consistent and throughout the entire RPM range!!

More graphs of the same runs with different data points I picked at 3500, 5500 and 6000rpm:







That's 15+tq at 3500! 20hp and 20tq at 6000rpm!
Talk about bang for the buck!

Run conditions:



Speed (all runs done in the same gear):




Driving impressions:

The car is an absolute monster! Complete animal! Not that it lacked power to begin with but the extra thrust combined with the sound of the intake/exhaust - I don't know how to describe it, it is just pure bliss!

Granted my tires are pretty old and worn - It is impossible for me to floor it in first and get any kind of traction whatsoever. I also noticed the car hops a bit rather than just spinning the wheels smoothly. I'm still on stock dampers and I'm guessing they might have enough control for my Eibach springs. Anyways that's another story.

I also had some concerns that sound levels would get a little crazy but not at all! The tone got a bit meaner and the car is a tiny bit louder but nothing drastic. Still 0 drone from the Supersprint cans and the cabin is still ridiculously quiet on the freeway. Just perfect!

And since I do not have a bone stock baseline I decided to take a look at my old E90 numbers on the same dyno:

(Peak numbers)

353/258 E90 stock
366/264 E90 with MS intake and pullies
367/261 E92 with MS intake and pullies
383/275 E92 with MS intake, pullies and pipes

Notice how similar the #s for both cars are with intake and pullies? Safe to say I just got a cool 30 peak whp from those 3 mods

I couldn't be happier!

Thanks for reading and also thanks EAS for yet an awesome experience! I will be back for some dyno runs when I get a tune!

Hell yes!!! That's awesome man. Really appreciate you doing this for the community instead of us all waiting for impressions and dynos. Some questions though: how much louder is your car now? Sound clips please? also you have to cut up your oem xpipe to put these bad boys on right?

My pleasure! I love this kind of stuff

The video I posted is actually a before/after. I don't know if you can tell a difference in sound... If you're in SD you're welcome to check it out in person.

But yeah basically the car is not much louder at all. Just a little bit. Little different/meaner tone. Love it

Edit: yes you cut the stock pipes to put those on

Take note everyone...This is how you write a product review.

Congrats on the new power man! Macht Schnell did an amazing job with the fabrication work.

This is very tempting...I may have to call it quits with the E46 M3 and start leaving a larger carbon footprint with the E90...

Does anyone know what this would sound like with a ACM exhaust? I have heard similar setups but curious to see how it would sound with just test pipes.

Tune should get you that much closer to the 400hp club.

What do these run?
I like the clamp-on system as long as it doesn't leak. I should make re-installing the stock cats easier for smog later on.
That driver side pipe has a LOT of kinks in it.

Thanks fellas! The car is fantastic stock but wow I'm having so much fun with it right now. It just begs to be floored; I want to say it takes a lot of maturity to not drive like a jackass More power + more sound just makes the car oh so enjoyable!

My car took fastest BMW of the day (and second place in RWD time attack class) this past saturday at Willow Springs with a 1:33.657. Not bad for having stock dampers and stock rotors/calipers. Must be all this extra power lol
