Quick notes on the installation:

The V-band clamps only need to be tightened to 70 INCH pounds torque.

And there is a small bracket and heatshield that will need to be removed to fit the resonated midpipe.

Other than that installation is very easy. And you can always call me if you have any questions during your install.

he asked a question TOny :P

 

I'm working on them. Custom made parts take a little while to get into production though.

 

yay! would love to pair up the ti dual tip exhaust with my new HR y pipe

 

Sorry if i happen to be jacking the thread but i heard MD is also making Test pipes and HFC. Is this true?

 

Or you could sell it and get the XYZ

Thats my plan anyhow.

 

Just got my Motordyne VQ system installed today.

Took off my HKS rear section and coupe midpipe. Sound is very similar to the HKS but is a more linear sound. I'm running a UT y-pipe that I need to swap out. Its rattling from scraping. But, it sounds great.

I need the XYZ pipe now... perfect time to change. I'll try to get a video clip up soon.

 

Very cool.

Your sound clip will make a very good benchmark comparison against Profanity Petes sound clip.

You have the VQ with the non-resonated mid pipe.

Profanity Pete has the VQ with the resonated midpipe.

It will be great to see/hear these two sound clips side by side. The resonator makes a pretty substantial difference on the sound.
.

 

Yes.

The HFC is already available as part of the XYZ. The resonated test pipes are next in line for production.

 

I think you got those backwards? lol

 

Tony sorry if it's a repost question but how do you resolve having two 02 sensors when people go to your single Cat option?

 

Ooops. Yep that's right.

 

Put the sensors in the usual place on the test pipes but the Motordyne test pipes will have a little something special for the sensors.

 

I'm sure I torqued mine down much tighter than that. Probably to like 30 ft lbs. Is that gonna cause any problems other than bending the screw a little?

I'm curious to how much of a different sound the resonator will make. My exhaust will sound different because of the headers and HFC that I have. I swear you can hear the headers all the way to the back now when I'm idling.

I'm moving and stuff so I haven't got a vid up...plus my y-pipe is rattling and makes me a little embarrassed

 

As long as its good now, its OK. For V-band clamps all you need is moderately hand tight with a nut driver and that will do it.

If you tighten more than this, just loosen it up and re-tighten to hand tight.

If you only have a regular ratched wrench you can use that too but be sure to tighten it with only ONE hand. And that should do it.


The resonator on the mid pipe changes the sound quite a bit. Without it, its louder of course but it changes the tone as well.

The difference is probably best left for sound clips to illustrate but without the resonator, it has more of a sporty sound. Like something you would more often hear on a 350Z exhaust.

With the resonator it makes it closer to the stock sedan sound.
