>>HP Autowerks<< Berk Technology N55 Street Performance Exhaust, Amazing Results!

HP Autosport · 10-05-2010, 03:25 AM

As you may or may not know, turbos need to breathe and due to the strict regulations but on BMW, the stock exhaust system on the new N55 135i leaves much to be desired in terms of flow and sound.

Thankfully our friends over at Berk Technology were already hard at work on our car as soon as it came out so we could offer you, what we believe to be the best option for unleashing that extra horsepower and torque.

Berk was finally able to get an independent testing done and it added an impressive 15whp and 20wtq from exhaust alone!

See for yourself:

What you want to look at is area under the curve of which this exhaust provides plenty. You'll notice the significant jump in torque down low at around 2700rpm and how the exhaust mimics the same smooth stock power delivery except only with more power all the way to redline.

This is a must have if you have done any type of engine work.

Here is the link to purchase, it is system #4: http://www.hpashop.com/product.sc?pr...categoryId=110

We also suggest to help the intake track breathe better, the addition of our stock drop in high performance filter. http://www.hpashop.com/product.sc?pr...categoryId=110

Systems good in stock and ready to ship!

System 4 is the Muffler Delete system. That Dyno specifies system 3, the street performance exhaust. Which is it?

Any N55 sound clips yet?!

So was the dyno done with or without a muffler?

ES BMW · 11-16-2010, 04:17 PM

Got confirmation that this was done with the rear muffler. Nice gains!

HP Autosport · 11-24-2010, 06:05 PM

And sounds great too!
