I fail at mathematic...
I fail at mathematic...
10% introductory sale = $230 off
+
10% cash back w/dynos = another $230 off (contact me for details on this one)
+
20% to 30% cash back from Microsoft = another $690 off
Up to 1/2 off or a total of $1150 for the Harakiri system.
But there are a few variables here.
Can you pre/post dyno it?
The Microsoft rebate is a wild card. It varies, but is generally 20% to 30%. (Either way its a good rebate worth taking.)
Shipping in the Ca. area will be approximately $45-60.
any specifics on the dyno discount? coz i have a pretty stock engine is that OK?
If you just need the car to dyno then knock yourself out! lol!
Need to save some $$$!!!!

Need to save some $$$!!!!Lets do it.
EDIT: I could dyno it for you but that would defeat the purpose. Only independent dynos have credibility.

Harakiri dual (with its mildly phase shifting color) is unlike anything else on the market so it occupies its own nich.

The Motordyne Dual Shockwave with Ti tips and the HKS high power exhaust compete on the same level.
Each is a full stainless system with Titanium tips.
The Shockwave is a hybrid of dual 2.5" combined with dual 3". The flow is progressively expanded as it goes further and further down stream. This configuration costs more to produce but it reduces pressure drop and increases HP.
The HKS dual uses dual 2.36" tubing all the way from front to back.
In all of my research, constant diameter tubing makes a system cheaper to produce but constant diameter tubing doesn't make for the best dyno results.
The Dual Shockwave (with Ti tips) has a list price at $1600, but after the rebates, the Dual Shockwave can be as low as ~$900.
The HKS has a list price at $1,895 and has sale prices typically around $1400.
A cost comparison for the above is self explanatory.
If you were to put the Motordyne Shockwave and HKS systems side by side and evaluate their individual parts and materials, you will see a significant difference. But I'll let you guys make that evaluation independently.
Side note: Ebay has been emailing out coupons for 10% off any purchase. If you have that coupon, you can use it in addition to all the other rebates and discounts.

The Dual has titanium tips. The sound is a little quieter and deeper than the single.
