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?

When they get to the close up to the exhaust, the after sounds like the Alfa Busso V6

remember that tampering with the exhaust system on any car will have an adverse affect on power-output and fuel economy, just because it sounds more powerful, doesn’t necessarily mean it is. Learned the hard way when my Toyota had a fractured exhaust manifold, and too many leaks along the pipe, there was a noticeable drop in horsepower and fuel economy, plus it sounded like a tractor before i got it fixed.

Unless it’s turbocharged, less restriction the better!

$200 for a bypass pipe?. You could gave gotten a whole catback system done up for at least $200 more. Would have sounded heaps better too.

$400 is barley enough for axlebacks… A Catback is over a grand, even more for a Porsche.

It’s called a gundo hack. Been a staple of the 996/997 community for years.

is it worth the trail of smoke he’s leaving though?

it doesn’t create any more or less “smoke” than before, it’s just the conditions in the after clips.
