went back to stock
 

ok got a 92 sedan with stock motor, i had a ractive muffler on and a short ram intake. i traded the muffler for a stock one( from a 94 integra rs) the whole axle back just bolted on. now im getting better acceleration. it seem like i lost power(which i dont have a lot) with the aftermarket muffler on. anyone else had these happen to them?

of course that'd happen :)

by increasing the exhaust flow you do tend to lose a little more torque :) Just like installing an intake on the motor, you lose more low end power, while supposedly gaining a little more on the higher end :) Most aftermarket mods like I/H/E tend to have the same effect :nods:
