tired of boomy exhaust

[maRS2]

Tired of booming exhaust at cruising speed

I want to make a back box with 2 entry tube and 2 out put tube

-First One 50mm tube with bafle inside
-Second One 76 mm tube straight through with ATP valve at the entry.

the ATP valve is opening with turbo pressure so that before 7 PSI or what ever you set it for the exhaust will go through the 50 mm tube and above through the 76 mm tube. like this you got two system in one.

I know Fujitsubo do one like that called "legalis viable" this for subaru but it's very expansive + have to adapte to RS2

I'm working in Thailand 2 week every 5week so could make it their as stainless building is very cheap if some intrest could make a small production for RS2/S2 avant

nice simple idea, just a matter of finding room for it all, the fujti thing was intresting and probably has a finer control since it uses a stepper motor to control the flap. Could almost have a 3" system with a single mid silencer and then a well baffled back box after a y pipe, once side with the valve in so that on boost the rear back box is removed from the system and goes straight out and not through the back box
