Built a Custom downpipe and exhaust system for i4

[Gcc91]

Hi,
New here just finished fabricating a custom exhaust as weren't many options for a bit of fun.
Going to put on dyno this week and attempt a tune. Anyone had any luck?

Cool! No muffler? How loud is it?

Bro, that looks so clean. And sounds great also!

Nice work. Does that bypass the valves too? Are you getting any drone at highway speeds?
