Blown Exhaust?

[Paul91]

During deceleration, My ARK-DT-S (Installed last year) is making a strange noise on the right (passenger) side. The best way I can describe it would be to imagine an oscillating fan with paper ribbons on it on high setting. It kind sounds like something is blown or baffling.

Is it shot?

I'm NA1. Completely stock.

Is it quiet at Idle. You need to rule out any gasket failure.

Sounds like a gasket or a cracked weld....

peak under your car and see if any exhaust soot is leaking from somewhere.

It's pretty quiet at idle. I'll take a look underneath. I installed it. There really isn't that many connection points with an exhaust, so detected a leak of any kind should be relatively simple..
