OK here's the deal. '05 Civic Coupe EX SE. Have put AEM SRI and just put on HP Racing header and exhuast last night. Came with a an insert in the muffler that knocks down the noise to that of a factory exhaust; although it stills has that deep rumble to it (Nice). There were two bolts holding the insert in place; took them out and pulled the insert out. Opens the exhaust up for a free flow of exhaust. However, the noise level goes up as well. Not so loud that I woke up the whole neighborhood or that you can't drive down the street without getting a headache.

Debate is this leave the insert out or put it back in and knock the noise level down?

Pros and cons on both sides? What are they? Will I lose gain or not, etc?

Thanks in advance for all the advice.

Spray paint it flat black then put it in.

Good idea but what effect on performance....??

idk if a muffler silencer can reduce "performance". its located at the very end of the exhaust pipings. i would only guess it would increase more back pressure as the airflow is jammed into the piping having a harder time exiting the pipes (muffler).

but leave it on and you can make not only your neighbors lives easier, but the public in general.


if this is on a civic, i doubt you would even notice a decrease or increase in performance messing with a silencer. i agree with painting it black, it hides. when it shows, it looks like ***.

performance wise with what you got you won't feel much of a difference with the silencer on or off. Just decide if you want it loud or not.
