buy a performance muffler
You could get a "turbo" exhaust system or "glass packs". An ovrsized exhaust (3 inch) can produce a slightly different, deeper sound.
Well, any change to flow of the exhaust gases will change their sound. That said, how much of a change in sound depends on how much you change the flow. Tips, normally go over an exhaust pipe and perhaps extend it a very small amount. It is unlikely this would cause much change...up or down.
Go with a 40 serious flowmaster 3 chamber muffler. That will make it sound deep and powerful!
Punch a hole in the muffler. (May cause you to fail a safety/emissions inspection) Ha ha.
Take off your exhaust pipe and muffler. It is against the law to drive a vehicle on public roads without a proper exhaust system. or you could take of the big round exaust filter and replace it with a peice of pipe or a hot dog exaust to make it a deeper sound.
Yes it can. the reason why is because you can get lung cancer. your voice will sound deeper
exhaust tip or glasspack it
A rumbling sound when a Civic Hybrid is accelerating could be due to an exhaust leak. When there is an exhaust leak too close to the manifold it can create a deeper rumbling noise.
a resonator restricts the sound in your exhaust. removing the resonator will give it a deeper sound. i would suggest changing the entire exhaust system and leaving he resonator off which would make a louder/meaner sound. leaving it on would silence the idle but when you rev it really high it would still be loud.
cut the muffler off is all i can think of but you could pick up a glasspack for about 20 bucks at the local parts house.
No, it will only make the exhaust sound deeper. however, note that over time, on some vehicles it will cause premature wear on the engine valves.
