A bit of a throwback to when we made Sri a custom cat-back valved exhaust system for his stunning 992 Carrera 4 GTS!

This exhaust is a bit hidden behind the back of the bumper, so here are some photos of it with the bumper removed.

It has greatly improved the sound of this turbocharged 911, with the option to make it quiet at the flip of a switch.

If you have a 992 and want more noise, get in touch to get booked in!

How good does this R34 GTR look! 😍

The owner of this car wanted a bit more noise from his GTR, so we made a custom cat-back exhaust system.

We haven’t made the car too loud, but it’s definitely a big step up from what it was before! As you can probably tell, this GTR is in unbelievable condition underneath as well as on top, making this a tasteful modification that complements the car perfectly.

If you have an R34 GTR, or any GTR, get in touch for a custom exhaust system!

How good does this Camaro sound? 🔊😍

We’ve just completed a full valved exhaust system on this supercharged V8. Not only does it sound incredible from the back, but the induction noise from the front is insane too! 🔥

What a great day testing our new setup on the drag car at Santa Pod yesterday! We made a few tweaks and we’re very happy with the results. A huge thank you to our team and everyone who came along and supported us. 👏

Who knows? The next time this car hits the track, it might be running a completely different turbo setup! 👀

It was also great to see so many of our customers testing at Santa Pod yesterday with the turbo kits and exhausts we’ve built for them! Everyone looked unbelievably fast and put down some brilliant 1/4-mile times.

Watch until the end for some sound clips! 🔊😍

We’ve just completed a full resonated, valved exhaust system with a Z-pipe on this SVR! The difference in volume with the valves open is insane!

Single exit on a Golf R!

We have been doing more and more single exit systems on these German cars, making for quite a nice mixture of German and J*p style.

This Golf previously had an overly loud system, which the customer found too droney. We have removed that system and fabricated a cat back resonated system.

The car is still loud, but now has a much better tone and won’t drone on long journeys.

If a single exit exhaust appeals to you, feel free to get in touch to book your car in.

We’ve just finished fabricating a custom manifold to replace one that had failed!

The original manifold had cracked in several places, leaving it completely unusable. Troy was tasked with producing an exact replacement, using the same specifications as the original.

The new manifold is now complete and ready to be sent back to the customer as a direct replacement.

If you need a custom manifold made for any vehicle, get in touch with the team.
