Review: Evolution Racewerks N55 Downpipe

Wanting more power out of my F06 640i GC I contacted Fred @ Evolution Racewerks to see if their recently launched F10 N55 downpipe would fit the F06/12/13. A few days later I was at their shop in Baldwin Park to test fit the downpipe.

After a quick tour of their shop, I was thoroughly impressed that they R&D, manufacture, and distribute everything in house. It was apparent that Fred and his crew are very passionate about their products.

Speaking of products, their downpipe has to be one of the best I've seen in the market... for any application. The welds are perfect and the fitment is to OEM standards.

The install took about an hour (we had to wait for the car to cool down) and the ER downpipe fit like a glove. At startup the stock muffler had a meaner growl to it and when revving the engine a more pronounced turbo spool filled the air.

Performance wise, the butt dyno can definitely feel a bump in hp and torque. The engine is more responsive when going WOT. This was while I was on map 1 of the JB4. Once switched to map 2, WOW! The added torque is even more noticeable and kicked me back into my seat when accelerating.

I wish I was able to do a before dyno, but will definitely do an after dyno very soon. Regardless, I'm very happy with the Evolution Racewerks Downpipe. It's worth every dollar!

Nice mod , what the expected hp gain ? 0-60 ?
Am searching for engine tune for my 640i CG ,but I don't wanna sacrifice my warranty ,
How was the installing of JB4 is it that easy that I can remove it easily befor service and install it again ? Any CEL ?
I also found kelleners tuning which give 374 hp ,

ER is estimating ~15-20hp to the wheels.

JB4 is one of the simplest tunes to install. I can install/remove in less than 10 minutes. No CELs.

Can you give us some more details?

I see that you mentioned that it came from an F10 Application, how would we order this.. its not listed on their site.

Was it modified to fit the car or it a direct bolt on?

Pricing? Etc.

Thanks!

Direct bolt on w/no modifications needed.

There's actually a group buy on the F10 forum going on right now: http://f10.5post.com/forums/showthread.php?t=907208
