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?

The gundo hack is child’s play. Real men replace the silencers with a 90 deg bend Thus saving 34 kgs and insuring your GF never wants to drive your car.
It does mean no trackdays though 106db 😕😂

My catback produces tons of drone. It registers probably around the 80ish dB mark. Its worth it. Daily your race car.

Definitely a thumbs up from me. Much more throatier, a little louder and I especially like that rumble on the over-run. Great mod that…
