[DeTomaso] Muffler Opinions

I had Borla XR-1's, and they sounded great.  They are 3" in, 3" out, and
about the same size as the original mufflers.  I sold them because I'm going
to 180's.

I like the sound of gutted stock mufflers.  I don't think they flow any
better, but the sound is a lot better.

The mind train exhaust sounds great, but it's also very loud.

There's a magnaflow muffler that is about the right size to fit in the stock
location.  It has 2 2.5" inlets and 2 2.5" outlets.  You have to make your
own y-pipe for the inlet.

You could make your own... gut some stock mufflers, increase the inlet to
2.5" or so, and replace the resonators with something that muffles, but
doesn't choke.

3" pipes fit.  It doesn't look difficult to take 3 u-bends, cut them just
right, and snake them through the suspension.  2.5" is probably big enough,
though, and would fit better.

All,
The new engine is in and running pretty good, but not perfect.   With 550
HP+, 
the current thinking is that my GTS headers / muffler set  up isn't big
enough 
to let it breath at the higher RPM's.  I have  secured Big Throat headers
from 
PI, and now am on a quest for a good set  of Mufflers to match.  Turns out
this 
is a pretty difficult decision, as the SOUND  is pretty important to me and
I 
probably won't have a chance to hear  them before buying. Obviously,
performance 
is the most important, but  the last thing I want is to end up sounding like
a 
tractor or, heaven  forbid, a Viper. 


So, I ask for your help.  What would match a high output stroked Cleveland 
engine with sound that will make the DeTomaso community proud?  (BTW, i
LOVED  
the GTS sound and  look on the previous, mostly stock engine).  I really
don't 
know the  entire solution space, so any info on what I should / shouldn't be

looking for would be helpful too. Options that are currently being
considered 
are:

1) Big Throat Mufflers (see: http://www.pim.net/862009Muffler4.jpg).   These

certainly are not conventional with the two pipes, but do have an  extremely

nice look.  and I like the option to angle them up (like the  GTS mufflers
do).  
Anyone running these? any comments on look / sound?

2) Borla - someone said "check Borla".  So I did at www.borla.com.  Not a
lot of 
info there, so not sure what would be a good match. 


3) Magnaflow - they have a nice oval with single inlet, dual outlet. (see: 
http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=8686).   The 
description says that it is meant for imports with mainly bolt on
performance 
enhancers, so I'm a little scared of this one.  Also, there  are a half a
dozen 
options around the tips, how does that affect sound /  performance? anyone
have 
direct experience with Magnaflow that can  recommend something?  


4) Cherry Bombs - Richard Boschert has the Extremes on his stroked Windsor
and 
they look and sound great. Plus they have a great video 
(http://www.cherrybomb.com/)

Sure appreciate your help and advice!!
