A Little Bit Of Metal Can Make A Stock 996 Porsche 911 Sound Awesome

By welding in a small bypass pipe between the inlet and outlet pipes, it's possible to make the stock 996's exhaust much more vocal

We love a good exhaust hack here at CT, and this is a pretty damn good one. It’s known as the ‘Gundo Hack’, and involves welding in a small pipe between the inlet and outlet pipes of the standard exhaust system, effectively bypassing the fun-killing, sound-deadening muffler box.

It apparently mimics the sports exhaust option the 996s originally had, and if you listen to the sound comparison above, you’ll see just how much difference it makes. Not bad for £200 of work, right?

The only downside is that it’s like having an active exhaust permanently stuck in the obnoxiously loud position, which could get irritating if you did this work to a car you daily.

Could you put up with the extra droning, knowing your back road hoons will have a much better soundtrack?

Please don’t tell me that’s legal. If so I’ll start to cry.

It’s not illegal…
only de-catting and straight piping are illegal in the U.K.

I wonder if you could put some sort of valve so you could block off the add-on pipe when ur mum drives the car then open it up for backroad hooning

It’d be a bit more work, but if you own a 996 you wouldn’t mind spending a little extra on that

if you can find a Yamaha FZR1000 Exup exhaust system (down pipes), it has a servo operated valve which does exactly what you want. just simply cut the valve section out and weld it in place as per video. then you can either setup a push/pull cable to operate it or a 180 degree travel motor/servo and operate it via a switch.

I wonder how this would work with a inline 4 or inline 6.
