Sila Concept exhaust

I received my Sila Concepts exhaust today. Everything looks great, tig welds are pretty good (I’m a welder so I’m picky), I’m excited to put the exhaust on my brabus.

I inspected the exhaust / welds further and I may have found some hair line cracks in the middle of the tig welds. I rubbed them down a little and the “crack” seemed to disappear a little. I can’t put a finger nail or anything in it.

I’m just wondering if any of you think it’s a crack? I’m not sure what else it would be. If I shine a light on it, it basically disappears, vice versa with natural light.

Hi, I've been involved in welding for fifty years and the welds look a little suspicious to me. You've got great pictures. I would contact Sila Concepts, sent them the pictures, and get their opinion. I feel the weld profile should be flatter. You could get a dye penetrant test kit and check them. I think the welds may have cooled to quickly.

Thanks for your reply. I’m not sure what happened with the welds. The lines are very strange to me. I don’t believe they are cracks though. You’re right, it looks like they could have used more heat.

In a hast, I installed the exhaust, and I’m very happy with it. It’s definitely noticeable, but not embarrassingly so. It’s throaty and has a grunt at lower speeds. It makes some good low throaty noise when accelerating normally from a stop. When you get on it it’s not as loud, but definitely audible. All in all am very happy with the exhaust. I’ll be sad to sell the smart.
