These are on sale for $175 (from $199) at http://www.horsepowerfreaks.com/
Looks like more cheap HP...but how does it sound? Anybody running these? I take it they're the 'non-resonator' type, as no mention of resonators was made in the ad...
Why do these pipes look different than all the other test pipes? It does look like a y-pipe, but I checked out the site you linked. I think these pipes might be for another car, not the Z. I could be wrong.
Besides, I thought I read a really bad review on Xerd. Hopupracing has Helix test pipes for $169. I've heard good things about them.
However, some people seem to dislike the 'raspy' sound of the Helix pipes at a certain rpm range. I think for a couple of seconds, I can ignore that sound for the power gain.
