apexi butterfly exhaust valves?

Ratsport

Hi guys, just registered to put a comment in on the ratsport system that is now out of stock. I think I got the last one

I got the system welded in and then hooked it all up, of course I tested the valve before hand but what I didnt realise is that the gearbox in the motor would go after about 10 uses. FAIL!!

The system is really bulky and a bit over engineered, I like things over engineered normally but when I was trying to tuck it in under my fat carbon prop it got a bit tight due to the size of the flanges. So I had to make it stick down about 10mm lower than the subframe, not ideal...

Anyhow, when it was working it was good but I think I will get this one working, take it off for sale and buy a different one from the US...

Here's a video of it working, It looks like it sticks out a mile in the vid (it doesn't). It was only a phone camera vid so the microphone gets killed byt the volume.

Easy to get a 3in one as long as you dont mind it not being JDM tyte--

Exhaust Cut Out Valves

Can have it as a Y piece thing, or in the actual system.

EDIT- Says out of stock! Its RatSport, prob worth ringing em to see if they getting more in.

Thing is, on tracks that have noise issues, it dont help you much as its useless aside from static tests.

Just to add to this, I bought the ratsport system, it's pretty solid, overengineered I'd say actually. Got it welded into my 350z in place of the midbox. However! The gearbox in the valve gave out after only a few uses, I didn't even get the car off the ramps before it was useless. I contacted ratsport and this is how it went....





Hi,

I bought an exhaust cut out valve kit from you recently. The kit is all
fitted now, on the first use of the valve on the vehicle while it was still
up on the ramps the motor/gearbox has failed. the motor spins however there
is no movement from its output shaft. Do you have a replacement you can
send out or upgraded units you can supply me to replace this one?

Many thanks.

Hi there,

Order number is: *************

Cheers,

Hi
Please return for repair quoting invoice number

I am assuming you would like me to return just the valve section as the rest is welded into the vehicles exhaust system? However, without the valve in place the vehicle is illegally loud on the road and thus undrivable while the valve is in for repair. Is there some alternative such as a spare valve being sent out for me to swap in in the mean time?

Cheers,

John

---------------------

Sorry we have no current stocks of exhaust valve or components, apologies for the inconvenience.

Ok, the next best option I can think of is if you can partially refund me for the faulty valve and using this I can look to have it fixed myself? How about £40?

That way I don't need to go without it and you don't have the hassle of posting in and out and the repair?

Cheers,

John

Hi​

Sorry we are unable to refund without a return (like most companies)​

Sue, can I send you only the motor off of the valve? This would be easier.

Cheers,

John

I would imagine so

had one years ago and was damn good at instantly silencing the car

now obviously you cant drive with it even slightly shut for any length of time or its bound to fook things.

but was basicaly wondering with it fully open is it still going to cause restriction to the point itll effect performance/temperatures etc?

as im wanting to run a completly straight through system going into shotgun type pipes

but there is occasion (i,e neighbours/dropping off other peoples gfs) where such an exhaust is going to piss people off. and if im only running 2 and half inch tail pipes, any kind of bolt in silencer is a bit of a pain

any thoughts?

Hello. Has anyone used the apexi ECV to make the car quiter? If so, what is your experience? I am pretty sure the new Porsches, Mercedes AMGs and the Z06 uses a similtar system.

I think all manufacturers are (or were) using exhaust valves to quieten down their louder performance vehicles.
