Hey All

Basic Info: BHR Midpipe with 100cel David Cat, Borla Exhaust

Was dynoing my car today, everything was going well then a burst of gray particles shot out the back of my exhaust.

I lost 60 rwkw of power straight away, car is alot more quiet, i gained 2 psi of boost (supercharge) and car threw a check engine light.

Since it was at pretty much 12am we did not have time to put it on the hoist, i am assuming my 100 cel davis cat is shot? and blocked?

Would the particles from the Cat damage my borla muffler? Is there any way of cleaning it out?

Regards
Jason
