question about blue flame slip on

[nakedlover]

just fitted a blue flame hi mount titanium can to my
03 s3. promptly removed the baffle. it sounded like
pooh with the baffle in, it rattled around in the can.
now it sounds sweeeet!
has anyone else fitted a blueflame and/or does anyone
know if I should do a remap? it seems like i've lost
some low end response as well as slight backfireing
under engine braking.
also considering a power commander / k&n filter
any comments on this would be much appreciated.
thanks.

unfortunately i don't have an answer for you, but i just fitted my blue flame can and removed both baffles (dual outlet can), but it's been raining for days here and haven't had a chance to run it except for my garage,
i'll be anxious to see what other have to say, for now, i love the can and the sound
