GTk Active Muffler for Air-Cooled Porsches

Awesome Exhaust

Very nice quality from opening the box through installation. Very easy install. The sounds are awesome. Create a very nice sound for long drives. But when it's time let everyone know when you have arrived just change the sound. I highly recommend . The quality is like all the products that I have bought from Auchtung for my resto-mod build.

Active exhaust

The system is very well built and fits extremely well however. Touring mode is still very loud and the exhaust drones terribly.

Making my 912 Rowdy

The quality looks amazing. Engine assembly almost complete. Going on a 2.7 twin plug stroker. I'll send video
