Anyone have those trick mufflers that come with a removable silencer?

Im interested to know peoples experiences with them, how

effective and easy to use....

I have been wanting an adjustable exhaust for ages :D

The other option is getting another less restrictive (loud) muffler made up which matches the existing flange, but this would require

undoing three bolts every time.

"Adjustable" exhausts are illegal. They need to be welded shut.

Mine has a central removeable silencer (one bolt holds it in).

It's not bad with it in, bit droney though. And it whistles/screams as you hit it.

With it out, you can't hold a conversation, listen to the radio.

T.

yeah I've got one as well. Fits into my cannon muffler to reduce the noise. Without it its impossibly loud to drive. Though the car actually sounds quite good when you floor it, it is abit restrictive but on the flipside without it I think it would attract too much attention from the wrong ppl.

My car came with a Kakimoto exhaust already fitted. It has a removable baffle (one bolt holds it in place).

Most of the time I keep it in - without it the car is a little too loud (especially considering how close I live to the local cop station!):)

Still, I think it is a great idea - you can have mean/loud for trackdays and stuff and quiet for the long runs...:)

isnt it obvious, your right its not rocket science :shake:

so i can have both!!!

cause i dont need bacon aggravation during the week, but want to hear the sound bouncing off tunnel walls on the weekend :)

think ill just get a new muffler thats stays just under 90db

My friend has an APEXI exhaust on his R33. It has one mutha ***a of a large muffler tip.

It has the butterfly in the exhaust and you can pull it or push it, to make it louder or quieter.

Once you pull it to make it quieter, it is signifficantly quieter but you also loose power. I don't think it even comes on boost.

Its a good idea now, because the cops are trying to crack down on exhaust noise here. Doing stops on thursday nights

THere you go - u can get them from takakaira.com

ECV N-Type A Skyline 93.8~98.4 ECR33 67mm ¥14800

US$126.

So about 200 + postage.

here is the description:

"APEXi produces state of the art, high performance exhausts which are known for quality, and deep aggresive exhaust tone.The new APEXi Exhaust Control Valve (ECV) controls the amount of exhaust flow from the exhaust muffler (especially the APEXi N1 exhaust muffler), and thus varies the loudness of the exhaust volume.The ECV is installed after the catalytic converter in a vehicle's exhaust system. It can easily reduces the exhaust loudness level by a maximum of 10dB by varying the butterfly valve in the ECV. With the ECV, one can now maximizes a high performance car potential with APEXi's range of high performance exhaust system; be it driving in urban areas, at night, or in areas with strict sound emission laws, just by varying the butterfly valve opening in the ECV. All these adjustments can be done in the ****pit via fly by wire controls of the ECV.The butterfly valve can be controlled in real time while driving either with the valve in fully opened, fully closed, or partially opened position.Before the invention of APEXi ECV, exhaust sound levels are control by using different inner silencers in an exhaust muffler.These inner silencers require vehicle down time to install, dismantle, and re-install to achieve similar performance levels of the ECV. Such changes also requires the exhaust to cool down in order not to burn the hands of the installer.The ECV replaces the connecting flange on the piping (after the catalytic converter) that connects to the catalytic converter.The wire that controls the butterfly valve on the ECV will run via the heat sensor cabling (as in NISSAN vehicles) and through an opening from the vehicle's under carriage to the interior of the vehicle where it will terminates at the valve control lever switch in the ****pit where it is within reach of the driver. Minor drilling & modification on exhaust piping after the catalytic converter might be required on other vehicle makes (e.g. TOYOTA vehicles)."

Here it is...i think its cost a bit too much though...

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
