tony, what exhaust does the black Z has? is that the VQ w/ Ti tips? does it really stick out like that?

I understand. IT is just a matter of time to purchase your product.


Tick tock....tick tock.

woooot! just installed the xyz pipe w/ resonator and got rid of my rasp problem. I have impul catback with FI300 cell. The rasp didn't occur until i installed the cats. Took out the impul V-pipe and put the xyz and bam, problem solved. Gonna put the Impul pipe up for sale now

Haha I knew I 'd get an answer like that. Can't wait to hear it.

hows the sound? impul sounded niceeee when i heard it on youtube

The Black Z has a dual Shockwave.

The tips are adjustable. You can set them in or pull them out to your taste.

Right on! That's exactly what it was made to do.

there are so many combination to choose from. For the most performance which ones would you recommend?

it sounds awesome! ill get a vid up this weekend. I think im going to order a straight pipe to see how it would sound instead of the resonator. Tony, do you think it will have rasp with the xyz pipe and the straight pipe? or what would be the difference with straight pipe/cat pipe

from quietest to loudest, does it go
resonaotor < cat < straight pipe? what im trying to get to is how much of a difference does each of those pipes make

The dual makes a little more but single weighs less. So its roughly a equal trade.

If the resonated XYZ eliminated your rasp, it will probably have rasp with the straight pipe installed.

The straight pipe will make it a little louder and brighter too.

yea i figured. But if we are just looking at the dual (Harakiri) is that it? what components would be to best improve performance. Is it XYZ pipe, test pipe, catback and no resonator?

MD test pipes, XYZ (with no module), Harakiri true dual midsection and Harakiri Ti rear section.

And the Harakiri Ti muffler/tips are absolutely beautiful. There is nothing else like it.

Any updates?

Just waiting on production.
