Drone? This word is way over used when reffering to Invidia. I prefer to call it Negative Throttle Wind Down or NTWD for short.
If you ask me, NTWD is very pleasent even in stock form.

 

great write up!


And for those that belive the Invidia's drone is killed by a test pipe....dream on

There's THAT word again. What am I going to do with you guys?

 

Do you realize how much pressure there is coming out of the engine? There is no way the heat would go back in the engine.

 

i'm sorry for my ignorance, so is it that blue now?? or that heat rapped orange??

The heatwrap layer is copper colored.
The spectum fiirewall is a hi-temp quietcoat-type liquid soundproofing coating that I added a blue tint to.
The Damplifier Pro is a high temp dynomat type soundproofing foil-lined mat.
I spray painted the final product with hi temp black paint.

 

Damn i want my tips like that

 

Take your invidia to a track...20 min of constant vtec will blue up the tip nicely. Put a silencer in to cut the flow of the driver side to force the flow to the passenger side to even out the look.

 

how much weight did you add by doing that?

 

before
raw unmodified Invidia catback weighed in at 29 lbs.

after
Multiwrapped Invidia catback weighed 39 lbs. (Added about 1 lb per foot of pipe)



In a magnaflow thread that preceeded this writeup, the stock mufflers were 20lbs each and the resonator was 15 lbs...so stock catback comes to about 65 lbs.
