Re: [DML] Re: pics of new exhaust


Great questions. Here are your answers:

1. Yes the Magnaflow muffler is quite close the front pulley.  A 
heatshield such as the one supplied with the Flowmaster would probably 
not work because there just isn't enough room for it.  The Magnaflow is 
more rounded than the Flowmaster.  For this reason, I insisted on 
getting the Magnaflow Jet-Hot coated just like the rest of the system.  
The Jet-Hot coating not only looks good and is long lasting, but can 
reduce temps off the exhaust by up to 55%.  So far, I have found the 
system to run quite cool and you can touch the exhaust with bare hands 
in less than 10 minutes after shut down.  I am going to try running 
without a heatshield and see if there are any accelerated wear issues.  
I will report as things come up, but I think things will be just fine 
so far.

2. The muffler angle is non adjustable on the brackets and bushings and 
is fully determined by the piping of the exhaust.  The muffler is not 
defective and the Flowmaster was a little bit lower on one side during 
test fitting as well.  I am bringing the car to a custom exhaust shop 
next month to see if they have any ideas. Only the anal guys like you 
and me seem to notice this though.

3. The supplied manifold gaskets were garbage.  I was unable to 
separate them without damage to either the outer metal part or the 
softer, crumbly inside part.  I tried using a razor blade, tin snips, 
and a dremel.  Sorry, but after pulling my engine I couldn't bare to 
use questionable gaskets on something that takes so much labor to re-do 
if it leaks later. Another owner used these gaskets and the headers 
leaked not long after.  He told me about the Volvo gaskets which are 
far superior but more expensive.  I don't care about the cost, I just 
want the best if I am going to do this!!

4. Overall noise level is louder and deeper than stock.  It sounds 
GREAT and almost brought a tear to my eye as I floored it down my 
street for the first time.  At low RPM's, say from 700 to maybe 1500, 
the sound is deep and loud enough to be slightly fatiguing if ran for a 
long time like that.  Once you get past 2250 RPM or so the sound 
completely disappears and is no louder than stock.  On the interstate 
today I noticed that at 75 mph there was absolutely no difference 
between stock and new and I could listen to my stereo or use my cell 
phone easily.  The sound difference (at least what gets into the cabin) 
is completely resigned to the lower RPM's, which is the way I would 
want it.  Who wants to be fatigued on the interstate?

I would be happy to provide any consultation anyone needs in this

Looks like a nice system you have there, can i just ask a couple of
questions , hope it doesnt sound too nitpicky!

1. The rear muffler looks awfully close to the 'front' of the engine
does this have /need any heatshielding? .
2. Is there any adjustment in the positioing of the rear muffler, one
tailpipe looks a little lower than the other?.
3. Any reason why you didnt use the main manifold gaskets that come
wth the kit?
4. Happy with the overall noise level of the system, particulary in
the cabin?

Looking to replace my own exhaust in the next couple of months.

Good work!

Kind Regards
