Glad to see, companies such as yours, still creating aftermarket support for the B5 Community!!! Great sounding exhaust as well.

Keep the iconic B5 platform alive and well!! Closed valve does not sound great at all, but open valve sounds good for sure. Good job though

Love this! It looks a lot like my ‘02 Laser Red B5 S4 6MT!! Sounds great but I’m keeping mine stock. It does have the ECS TSI ignition upgrade to eliminate constantly failing ICMs.

Nice car, the open valve one sounded sweet. 🎶

I would love to hear this exhaust paired with catless downpipes.

[@steveschmidt5574]

No soft limiter here! 🎉

I want to inline 5 swap a B7 S4 for a daily, so badly.

[@rav4l2003]

That’s cool. Those sound even better than this 2.7t v6.

[@Sebbylagana]

im looking on your website, but i dont see an option to have it resonated or not. Can i purchase it with just the muffler or do they all come with muffler and resonator?

Meanwhile I’m over here with a 2.8 and zero aftermarket support 😂

Closed valves sounds like poopie, it needs work, at least on video. Open valve sounds nice.
