Yes, I actually did away with mine years ago.  Not long after replacing
the center section with new (expensive!) parts, the new center muffler
had an altercation with something that split it open.  I decided it
needed more clearance so I had a pipe made that goes from the cat to a
Supertrapp muffler all the way at the rear....<snip>...
I have been thinking about adding a very low profile muffler back in to
the system and making a hole in the Supertrapp endcap..

hello alfisti
I am contemplating removal of my 93 spider center muffler.
Has anyone done this?  any commenets re: the exhaust note.
how loud, how pleasing, displeasing/  any changes in
performance noted? any disadvantages?
all help apreciated
My personal opinion is that the center muffler is the most important in determining the sound of a 105/115 Alfa. Without a center muffler the exhaust note is too loud for my preference. The size of the center muffler "can" varies among the Ansa, OEM and aftermarket replacements. The smaller "can" size will produce a louder exhaust than the larger can, but since they are straight through designs, I doubt there is much performance enhancement offered by smaller/louder center mufflers, but (IMHO) the sound is a more pleasing note. The absence of the center muffler produces an exhaust note too boomy a for extended driving or conversation with a passenger.

My favorite center muffler for sound was produced by Ansa and has a smallish can size of 3.5"tall x 7"wide x 12.5 long. There are a lot of larger Alfa center mufflers out there of the size 5.5"tall x 10"wide x 13.5"long, which are significantly more quiet. Recently I found and installed a Magnaflow muffler to my GTV in the center position. This size is 3.5"tall x 7"wide x 14"long (2" ID), part number 11114, cost me $65. It looks to be very well made, good sound is muffled but loud enough so that the engine can be heard. The dimensions make it pretty thin, but a tad longer than the Alfa equivalents. It will need custom installation. I'm happy with it.

Mufflers and exhaust notes are really personal. YMMV.... //kct
