Berk Exhaust Production with X-Pipe

Matt

In the few days I've driven since installing the BERK exhaust, I have to say, the butt dyno approves! It feels incredibly more responsive, especially in the 3-6k RPM range. I would be surprised if the BERK CBE/HFC combo hasn't added 30-40 whp.

And I have to say it again, the "harshness" of 6.5K+ in this engine is all but gone with this exhaust. I'm sure it's still "there", but I no longer can feel/hear it. All I hear at 6.5k RPM is magic.

I completely agree with the above statements, especially comments about the 3-6k rpm range and the apparent lack of harshness above 6.5K. I can't explain that. Engine feels like it's running a lightened pulley or something now, weird. Just seems to rev more freely. VVEL FTW!

One other thing I immediately noticed. The mechanical sounds of the engine sound better, especially with a throttle blip from idle. Also weird, but I like it. And this I can explain...with a less restrictive exhaust, the loudest noise now comes from the tailpipes; with the OEM exhaust it seemed like the noise was emanating from the resonators, almost from underneath the vehicle. Less noise in the cabin when cruising!

I 100% agree with everything you just said. My car really came alive between 3 and 6K with a huge boost up top past that all the way to red line.

Its funny that you say the high RPM harshness is gone, I took my mom for a ride yesterday and was commenting to her that the engine is much smoother now up high. All in all this exhaust did wonders for my car. I'm very pleased with it! Good job Berk
