That night I put on Berk Test Pipes and ARK True Dual exhaust. Both parts were made with great quality, But...

After the install I started the car and let me just say it sounded amazing!! But then it started... There was a very high pitched whistle/humming/hissing noise from 3.5k-2.5k rpm's on deceleration. I kept it on the lift and had a co-worker check it out this is what we found.

Due to the increased Exhaust Flow because of the Berk Test Pipes the Xpipe which is on the ARK exhaust system created a wild loud howling whistle. After contacting the ARK they agreed with my conclusion, I am going to send back the exhaust or sell it.

The exhaust sounds great without test pipes or HFCs but im going to keep my Test Pipes installed especially after tackling the "Demon Bolt". which I killed in an hours time for removal of stock cats and installing the test pipes.


Here are some pictures of the install, The new Exhaust I am planning on getting is HKS High Power it is a very similar set up to the ARK but incorporates a "H" pipe rather than a "X" pipe

I am also planning on doing Dynos after installing the new exhaust just waiting on some companies to get back to me.

This is a Stock exhaust on a cold start with some rev's to 4k

All of the flanges bolted up square, All of the welds were solid, and the adjustable tips are very usefull.

I cant wait to get back to Sound Performance and see what the gain is with the Berk Test Pipes and HKS exhaust

Here is a video clip, Play this on a good speaker set up otherwise its not doing the exhaust justice. There is a little hint of a Hiss in person and for some reason its amplified by the video, But under load there is no trace of it.

Enjoy

I know that they are not going to give me the crazy power that the G3 Stillen intakes are known for, but for a total under $300 including these Post MAF tubes and Drop in K&N filters Im happy. Also Didnt make sense to spend 500 on intakes when Im going FI in the Future.

I will post pics this week of them installed, Going to call Sound Performance on Monday to get some dyno time

Remember my Baseline dyno results were very good 282whp were the results on my Stock 09 370Z 7AT...... Now I am making 304WHP that is a gain of 22WHP from Berk Test Pipes and HKS Exhaust!! I am a very happy guy

Below is a picture of the Dyno sheet with baseline so you can see how the mods gained HP throughout the entire RPM range. Also there is a link to a video of one of my three runs.

Also I went and had a little photoshoot with Blackie once he is done going through the photos he should be posting them for me, Thanks again Young!
