I ordered some Berk Test Pipes for my 2006 350Z from B2AutoDesigns which was GREAT to deal with. It shipped the next business day (Ordered Sunday) and they were VERY easy to contact. Also had free shipping. Will be doing business with them again, anyways upon opening the box Berk gives you brand new bolts, pipes, gaskets, and even a poster. Thanks Berk.

Upon installing it took me about 45 minutes to get 2 bolts off because my impact gun couldn't fit and I didn't have an extender. So I took it to Nissan at about 10:00 pm since my friend works there and used there bay along with there tools. Besides getting the rusted bolts, install was very very simple. I guess thats why they call it bolt ons. It took about 45 minutes to get the bolts off and about 20 minutes to put the new pipes, bolts, and o2 sensors on.

Test Pipe Review (Keep in mind I have a Borla Exhaust that came with the car):

The exhaust is much louder, sounds a lot deeper, and much more aggressive. Since the pipes aren't resonated it does have a decent bit of rasp, but it's not as bad as most people describe so far I don't regret it and the sound makes up for it. Acceleration seems like it is better then before. As far as horsepower gains I'd have no idea without a dyno. The only reason I got these was because of the price and the sound mostly.

Would I recommend these?

I'd say to anyone who doesn't mind some rasp, and a much louder, deeper sounding exhaust system. Yes.

Hope this helps people who are considering test pipes. I will upload a video once I find a good enough video camera for the sound.

Thanks for the read.

Will try for a vid tonight, so far no CEL light within 60 miles, the pipes were about $170 so not bad at all in my opinion.

do they give rasp when used with HSK exhaust/hks clone etc?

I took mine out, CEL kept popping up even with the o2 fix. Not worth losing low end torque, no gaskets came with mine so I shopped for some @ www.courtesyparts.com

As soon as i installed my Berk test pipes on my 04 z, i noticed a severe rattle coming from the y-pipe on my invidia gemini exhaust when the rpms drop to around 2k rpms on decel or clutch disengagement. The car sounds good other wise; just wish i could stop the rattling!

you may be referring to the "hissing" noise that is talked about with most test pipes. if so, then yes my berks do the same thing. but it doesnt bother me.

Sold them at the same place where you got ur headers from.

Bmurray350z

thats the way to do it! but when i said "waste your money" i was referring to:
spending $400+ on hfc's while you could spend $160ish and get test pipes, not to mention with a little more power gains.

not so much a hissing noise. Its sounds like metal vibrating against metal. Its quite embarrasing.

were definitely talking about 2 different noises, because it sounds nothing like metal hitting each other.
