So I'm following up on my progress on drone/heat suppression on the exhaust pipe itself under the cabin.
Here is a great comparison thread on Sound dampening compounds.

http://www.sounddeadenershowdown.com/

From this comparison, I found a High Heat resistant liquid dampener called SecondSkinAudio Spectrum Firewall

http://www.secondskinaudio.com/cgi-b....cgi?pg=2&p=ps

I coated the heatwrap to waterseal and add to heat/drone suppression on the pipe. I then TESTED to see how well it would hold up at the TRACK


After 150 TRACK miles (5 thirty min sessions) this is what it looked like




You can see the hottest portion of the pipe is where the resonator use to be


Looks like it held up very well so I will give it another coat and continue my experiments

Very interesting...

I love the sound of my T1R but now that I'm single and dating again, the ladies don't seem to love it as much as I do... I'm just worried about the piping holding in the heat and damaging.

Would you say your car is as quiet inside the cabin as stock now?

Ever since I put the testpipe in, the db level at WOT increased at least 50%. The 3k-4k drone in the cabin went up about 25%.

After doing the heatwrap, my drone is back to a livable level but by no means are we even close to a stock db level in terms of drone or WOT.

I noticed that covering the "Y" portion of the pipe really attacked the drone frequency so I am still concentrating there. I LOVE the BEAST level these magnaflows tune to so I am hesitant in start partially covering the cans themselves. At some point I will probably coat the top of the cans and I will post up then.

I too LOVE the roar. My wife on the other hand So I am seeking the compromise and here is the diary of that journey.

Holding in the heat is not the problem you should be focusing on, its the corrosion angle that has me on edge. I have had this wrap on since November and have had a chance to check under the wrap and found no corrosion which I attribute to the Boeshield I coated the pipe with prior to wrapping. That's why I have now coated the wrap with a sound deadener to waterproof and continue the drone isolation.
You rock man, thanks for the thread. I will be looking into this.

wouldn't this lock in moisture, salt, etc. from wintry and wet roads, causing your expensive aftermarket exhaust to rust prematurely?
