I have a knock off N1 canister muffler on my 4 integra, when i take the silencer out the car runs like absoulte ****, its loud a seems little sluggish, with it in i have better low end and smother thought the band... is this normal?

 

not my teg. it seems to be holding back when i have my silencer in, but i do like it quiet sometimes.

 

it does pull a bit better at 4k but its really too loud, but the rest of the band is much better with it in

 

I think it's just you... the silencer is creating a bottleneck.

 

what kinda piping do you have? and do you have an ls? i wont be suprised if someone see's gain with a silencer in a 2.5 inch exhaust compared to the silencer off.

 

i have 98 ls motor ,no cat ,18"resonator 2.5 piping

 

i have read that the silencer is supposed to give u a bit more low end power.

Is the rest of the motor stock? If it is, i wouldnt be surprised if it ran better with the silencer in, 2.5 piping with no cat is wayy too big for a stock motor.

 

what kind of header do you have do yourself a favor and put a vtec head on that thing. it wont be as bad. but daily driving u mite feel it lag down low a little.

 

Ya, with a stock motor the 2.5" piping is a little much. Basically your exhaust is out-flowing your motor, or flowing enough to support a motor with more output. Having the silencer in gives you backpressure which will give you better bottom-end torque and will let you get off the line slightly quicker during normal driving. Having the silencer removed should give you better response and output at higher RPM's, which the LS doesn't do well with in stock trim anyhow. Get more air flowing through your motor and you'll enjoy the free-flowing exhaust more.
