Active Exhaust Cutout Valves - now with videos!

[Greg_S]

It would be a bit heavy

Lol yeah, but Andy's on a budget

[Rusty]

Yeah, a budget

I'm well tempted by one of these now, started the car up with the windows down earlier and it sounded grrrrrrrrrrrrrrrrrrrrrrrrrrrrreat

[Big Lee M]

How about this, my brother just shown me it as he's into his jac crap................Quite cheap and manual. It fits between the flanges and is 3".

I know but he's said he's on a budget

That one you have pointed out is a fancy bit of kit and cheap

[Rusty]

I'd spend a few bob on this as it would make the car sound ace and would improve performance too £300 would buy & fit a fully controllable one with 3" dump pipe under the car. Have to wait and see.

Cable one is cheap but you don't get the Y pipe so it's not that much cheaper than the QTP item. That Summit racing item looks like the QTP one too.

Add this option to the modular exhaust idea then...

[Rusty]

I've got mine planned already ... Just need to still have a job come Monday and get back to health so I can go and get it fitted... no small tasks then.

Good luck with the job dude.
Being a Grad were stil not sure what is happening with us, personnel are yet to decide ive got to come in on tues as normal, but i could get a call at any point next week for a consultation.

Like this valve idea, ive kinda got used to my single box system, fancy a bit more volume yet again now.

[Rusty]

Cheers James same to you too mate.

I would go back to a 2 box system with the valve after the centre box if possible. I've got a spare centre section with a silencer on it so could have that hacked about. Not going to happen for a bit but for pure grins this gets 10/10

Had the car running in a very narrow wallewd street yesterday, WOT in 1st was like heaven!

[Rusty]

Bit of an old thread but I've just booked the car in to get a valve fitted next Tuesday Hope it's worth the effort

[Error404]

cool, what did you go for mate? How is it controlled?

[Rusty]

It's an electronically controlled proportional valve (you hold the button down for a few seconds to open fully and as it opens in discrete steps, you can open it a little or a lot). I'm getting it fitted by Prospeed in Cardiff, as they fitted the exhaust originally and have done any changes and upgrades since.

Placement and size are TBD, as I can go for a side exit 3" under the rear seats with a pipe sticking out in the traditional side exit position, just forward of the rear wheels or a 2.5"/3" with down swept tail pipe just alongside the rear silencer. There are lots of options and I'll make sure I look into which one is best before I take the plunge.

If I was having it fitted from scratch, I'd run it in parallel to the rear box and out one of the twin pipes, for a really neat design but that's not possible, due to the rear box I have being too large and the cost of getting it re-done.

Price wise, it was either have the rear section made in 3" from just under the rear seats (it's currently 2.5") and risk it being boomy and loud all the time or have the valve fitted and keep my near stock sounding exhaust but with the added option of going to full Group B spec noise levels for the same money and having a freer flowing exhaust, due to there being no silencers between the cat and exit.

[Masterblaster]

I will try one these.

I believe that Prospeed use these valves -
