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.
Punch a hole in the muffler. (May cause you to fail a safety/emissions inspection) Ha ha.
Put in a Borla cat-back exhaust, you will be greatly satisfied.
buy a performance muffler
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.
The main purpose of a resonator is to reduce exhaust noise. Removing it will give the car exhaust a deeper sound.
You could get a "turbo" exhaust system or "glass packs". An ovrsized exhaust (3 inch) can produce a slightly different, deeper sound.
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.
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.
You want to start with at least a 2" system. At the motor, you want a set of headers, followed by high-flow Cats. If you car is pre-emission, then just go with dual exhaust and glasspacks; they get louder as they get older. if you have anything stock, forget exhaust sound. At the end, put a tip that is slightly larger than your exhaust tubing, such as 2" tubing to a 3" to 3 1/2" tip, it will give the exhaust sort of an echo that makes it a lot deeper. Or you can just buy a tip to go on the tail pipe. It's cheap and will not mess up your exhaust system.
6 x 9 for back speakers!......... front speakers should be 6.5 and depth is at 2inches. You cant get anything that is 2inches or deeper without cutting into the car.
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.
To clear a blockage from a blocked exhaust, first, turn off the engine and let it cool. Inspect the exhaust system visually for any visible obstructions, such as debris or dents, and remove them if possible. If the blockage is deeper within the system, consider using a high-pressure air hose or a specialized exhaust cleaning tool to dislodge it. In severe cases, it may be necessary to consult a mechanic for professional cleaning or repairs.
