Hi Brian:
I am glad that your setup worked out. Much as I would love to claim the
credit for the initial idea, I cannot. The original notion was sent to
me on the list by Robert Rudolphi who wedged his baffles in with tape
wrapped around them. That lasted about 3 days on mine and then I used
the side-bolt that comes with the kit. I can claim a rather cunning
cross-brace installation for the Falcon Sport that gets the mufflers
much more out of sight, but the 4 JCW baffles are Robert's input. Alas,
even the initial notion of a brace was from Marc Nederkoorn of Holland
who has one on his setup. Curse this honesty!
I must admit I am amazed that these things don't stuff up the car like a
bad cold, but they really seem to help without reducing power etc. I'm
sure that they would adversely affect a race car, but for a highway and
occasional country lane touring it answers nicely.
Cheers,
Mark

Subject: [TR] TR6 ANSA exhaust - now quieter after installing inserts
I had commented on the List last week that my new Moss-supplied ANSA TR6
exhaust system was too loud for my tastes - it was hard to hold a
conversation
at any steady throttle setting. It seemed to really boom at 2500 RPM
where I
do most of my driving in 3rd and 4th, straight or OD. The ANSA system
has a
lovely, rich, multi-toned sound, but it's tiresome on a longer drive -
and
could be embarrassing (ie Harley-like) in traffic.
A while back, Mark Hooper from this List suggested that I try the
motorcycle
baffles produced by JC Whitney. Mark had used these on his Falcon Sport
system and said they made a 'whale of a difference'. These are simple,
inexpensive, stainless steel baffles, about 4 inches long, that you
insert in
a straight portion of your exhaust pipe. They come in two sizes: 1.25
and
1.50 inch diameter.
Here's the JC Whitney web link:

I took the TR6 to a local Midas shop last Saturday to have these
installed.
They simply cut the two exhaust pipes in the middle of a straight run,
inserted the baffles, tack welded them in place and butt welded the cut
pipes
back together. Other than the butt weld, the whole affair was quite
invisible
- you would never know they were there.
Do the inserts work? Absolutely. I would say that the exhaust note is
now
about 15 to 20% quieter, the lovely ANSA sound and multi-tones remain
unaffected, and it now meets my subjective loudness tolerance level. On
the
whole, the ANSA system with the inserts is marginally louder than the
stock
system, but not so much so that it's irritating.
So, for anyone who has an aftermarket exhaust system that's a bit too
loud,
you should try these inserts. They won't cut the sound level down by
half,
but they will take the edge off and they're virtually invisible from the
outside. Mark Hooper, if you're out there, thanks for the great advice.
Cheers,
