Any Body Help!
to make a long story short:
i had flowmaster exhaust
i wanted somthing louder
took off the flowmaster and put a straught pipe with a muffler in the end tip sorta thing
had no power from 5-6 RPM
could not take it over 100 because of this problem
i was told (and thoght) it was the fuel pumps
changed the fuel pumps
still no power in 5-6 RPMs!!!!! AND CANT GO OVER 100 BECAUSE OF THIS POWERLOSS
could it be the exghaust?!! even though it is a high preformance tip???
PLEASE HELP

BACK PRESSURE.......
some cars require it. Had an RX7, when i did the exhaust mod (no cats, dual straight pipes, and 1 resognator) i lost all my back pressure, which controlled a valve that allowed ports to open/close. Top speed before exhaust mod 135, after mod, 102....
Obviously a benz is 150% different, but something to do a search on.
