I don't understand why your loss of backpressure leaves you with less
performance...if backpressure improves performance, your motor is not tuned
correctly-

Subject: DML: V6ers-Running no muffler is indeed a bad thing
Well I should have known something like this was going to happen...
After giving my Dak a tune up, having the tires changed, and even changing
the
timing belt without swearing ONCE, my streak is over. I ripped my exhaust
apart
this weekend getting firewood by driving over cable fenced that decided to
jump
uo and snatch my muffler. Tore pulled it apart at the ypipe-meets-main pipe
connection completely. Loudest a truck of mine has ever been.
I got under there today and tried to put stuff together. The exhaust had
also
TORN out of the rubber hangers and twisted the one metal hanger so badly I
had
to try straighting it. No go, my little brother emptied every gas tank in
the
house. On top of all that, the y-pipe and main pipe were clamped so tightly
from the factory that they don't go back together.
After an hour and a half of wrestling with and exhaust system that weighs as
much as I do I gave up, heated the room with every curse word I know, beat
the
crap out of the muffler with a ballpeen hammer, and finally cut the muffler
apart right in front of the muffler.
I know I shouldn't have lost my temper, but I feel a lot better now and am
in
back in touch with the true me :) Besides this gives me an excuse to
upgrade
the exhaust.
After cleaning up and cooling down, I took the Dak for a test run too find
any
performance difference. Soundwise, you can't tell the cat is even on, it's
just
stinking loud. My parent heard me from 5 miles away in a hilly wooded area.
Powerwise, I did feel a gain from 2-4K, but trhere was a definite loss from
the
get go.
Tomorrow I am going to have the y-pipe welded to the main pipe, and I'll get
a
clamp to strap type clamp to hold together what I cut off, just so I don't
get
pulled over. I'm thinking of ordering the Dynomax aftercat setup ($105 in
Summit). Does anyone else have this? Is it truly bolt in or am I going to
get
frustrated and cut something I shouldn't? Power vs. sound?
Thanks for reading all the way through and allowing me to vent :) and
thanks
for any help as I now truly begin to "fix" my truck:)
