The single and dual are very similar but with a small edge to the single.

The diffuser tip reduces exhaust system pressure drop by 0.7 PSI. ...It also enhances the sound quality.

Yes, the diffuser is louder than a regular tip but it also does something really nice to the sound quality. You have to do a live side by side comparison to appreciate it. It reveals engine sound detail that doesn't come through on video.

 

ok cool i figured knowing you there was a good amount of research that went into just the tip. But i wanted to see what the power difference was between the two. Still trying to get some money together lol .

 

You could potentially incorporate the diffuser tip into a more traditional "shell" (strictly for cosmetics), could you not? For those that would want to, I could see an exhaust shop fabbing Ti cylindrical tips over the cones...

 

Anyone know how much power it will make with just the exhaust and not the XYZ pipe? will it make a bit more power than stock if I just buy the exhuast and not the XYZ pipe?

 

Yes it will make more power than stock, but for best results you need both.

As the current trend shows, without the XYZ pipe, it should still make a couple extra Hp over any other exhaust that does not swap out the Y pipe.

It will make gains but it will definitely do better with the XYZ.

It also sounds a lot better too. The stock Y-pipe sound is somewhat dull.

The sound becomes a lot livelier with the XYZ. Its loud yet practical and the sound quality is awesome.

But look out if you add unresonated test pipes to it... WOW!!! Its 10X more intense and krackels like lightning bolts are shooting out of the tip.

Its not for everybody, but damn I love it.

 

Yes, I'll be trying that next. I'll post pics.

 

Your in Cali too. How are those tickets treating you?

 

No tickets. ...Yet

In fact, I've been driving around many cops with no reaction.

I even had a cop on my tail after turning through an intersection... no reaction. But I made sure to barely touch the gas pedal on acceleration.

All it takes is one good stab of the gas pedal with a cop around to get. ShockWave on test pipes is 110% street Illegal.

Of course the axle back section of ShockWave can be switched out for the VQ muffler for near total silence. Or the Harakiri or Gamma muffler as intermediates.

I switch through them from time to time for a nice change.

 

I want the big single performance with my 3.5 tp on my tt setup but damn if i dont want to wake the city when i'm out street drifting at night. What would be a good road to take, man?

 

The Harakiri single is much quieter than the ShockWave))).

But if you are running a high power TT (600+HP) system you may want to wait for the full dual 3" system.

The dual 3" system will also have all the axleback options of ShockWave))), Gamma and Harakiri but I will put a lot of effort into making the option for both quiet and high power simultaneously.

I know a lot of people need quiet and high power together on their FI systems.

 

I've been looking for information on the Gamma and Harakiri singles

Do you know of any websites or distributors?

I'm not in the 600 ball park and i don't intend to be so it's not an issue.

I'm probably going to stick my my oem y-pipe until you release a 3" xyz. Cause I'm cheap... lol

 

I'll mention its also very easy to do , it takes me about 2 minutes to do the swap


The XYZ is 3 inch

 

is the shockwave a 3 inch exhaust ?

 

XZY is 2.5

And to the other guy, yes, the shockwave is 3"

For the limited introductory phase, there has been quite a few dynos, sound clips and pics posted recently... and more will continue on different configurations.

 

Yes. The XYZ has 2.5" primary tubes with a tuned 3" collector outlet.

 

I just wish you made a harakiri that looked like the agency power or the aam like originally planned. I dont like the way that would look as a single for NA guys.

 

All feedback is appreciated. It all end up being used for making improvements.

 

im waiting to see how it will look when you put tips on it.
