Is ther anyway to insulate the exhaust to prevent the noise from entering the cabin? I put a Ti exhaust on my car and it sounds great outside the car, but is insanely loud inside the car even with the top down. I havent tried a silencer yet, but is there anyother way to prevent the noise from entering the cabin?

 

You can try to insulate the underside of the car. This has been described in a couple of threads here.
Unfortunately, this is the price you pay for having this type of exhaust. You should not be surprised. Any sound deadening is only a vague attempt at undoing what you've already paid big bucks to do.
Last resort: EAR PLUGS!

 

If I recall correctly one of the board members was putting together a soundproofing kit. Maybe check the For Sale or GB forums also.

 

I can't be breakin' the laws of physics, Captain. At these frequencies the sound will just bend around and enter the bridge.

 

Try the silencer.

 

Hey Dave, just don't start the car

 

What is the purpose of getting a sweeter sounding, louder exhaust and then installing a silencer

 

I dont know the Ti layout, but thought I would throw in some of my experiences.

I've found that one really important consideration is the location of the mufflers or resonators. The original designers spend weeks/months modelling and testing muffler designs, and one really important thing are the resonances in the pipes. Moving mufflers closer of further away from the motor can change the note, tune and interior noise level. They even use dead end pipes to change resonances. Putting a resonator mid distance increases the natural frequency to avoid booming resonances.

If you remove a resonator in the middle of an exhaust system you can introduce a full system resonance which in the mild form will have an real annoying booming resonance in the car, in the extreme it can shake your headers to bits. I've even seen it so bad on one car that the CD player would eject the CD at certain RPM.

My general rule for high flow systems is to put the resonators/mufflers at the same distance from the motor as the original design. If the system has two mufflers, use two resonators or one resonator and one muffler in the original locations. This way you retain the original "note" of the system ( but louder) and avoid any full system resonances.

You may want to try putting a high flow resonator back where the original one went if you removed the Honda one. Converting a duel outlet system to a single is OK, its the total length of the system and relative positions of the components that seems to matter. For your calculations just measure up one of the original outlets from the engine or average the two.

My 2 cents for free.

Speedracer.

Otherwise, you could get a louder stereo.

 

I tried the silencer and it sounds ok. Its sounds just like a silenced exhaust. (go figure) It eliminates all the booming and everything, but im not sure if i like it. I am looking at putting in a resonator, but it is my understanding that you have to weld TI to TI. So if thats the case i would need to find a TI resonater. Oh well, Im open to suggestions if anybody has em.
