08g37 · 09-03-2010, 09:48 AM

!!I read few posts on this forums who did muffler deletes I thought id give it a shot got some custom pipes and tips and had it installed btw I have a INFINITI G37. Start the engine and it sounded freat but the drone in the car with the windows up is driving mr crazy I think it sounds louder from the inside then out ! Anyone have any idea how I can muffle the sound in the cabin? I tried putting some cardboard paper above the spare wheel underneath the trunk which kinda help but not much anyone have any ideas?

Sound deadening in the trunk will help, such as dynamat

Also, make sure there are not exhaust leaks, and that the tips extend past the rear bumper.

why do this if the noise bothers you? How much can you really gain compared to a quality CBE?
