Just have to add to the thread a little more!! Today on the way home (on
the home stretch, no pun intended) I made my last turn then once it was in
2nd, stomped it to the floor until I hit 6K, shift, 6K, shift let off. I
was close to 100 and this is the 1/4 mile section that I test my car on. I
am now a FIRM believer that these 16v motors NEED some back pressure for
them to be at the top of their heap. I think I can actually feel the rest
of the stuff I have added to the engine come alive now as well. Now I can
understand how Shannon feels: "This piece of crap car" "This car is sooooo
bad!!" "What a hunk of junk" "Man that thing is running harder than
ever!". A few little tweaks one way or the other can REALLY make a
difference on these motors especially when the get crankier with cams and
high compression and stuff. Anyhoo, just thought I'd brag, or I mean fill
you all in!!

Subject: RE: bit of confusion on exhausts
> Well, I don't know why I didn't think of this before, but does anyone have
good aftermarket muffler reccommendations? I'm looking for something along
the lines of low purr/growl as opposed to high, annoying buzz. I have some
Audi muffler on now and it doesn't sound like much at low rpms but when I
step on it and get into the higher rpms its got a really nice, deeper hum.
Here is what I'm looking at for mufflers. I'm going more for looks and sound
than performance.

what's inside, where as #1 could be stuffed with cotton for all I know.
Also, 2 and 3 are straight through. 2 has the typical canisters on rice cars
which makes me leery of the fartcan sound but 3 is a bit expensive.
