SVX is smoking on precats

Hey guys so I just seafoamed my car. While it was smoking I happened to notice smoke coming from the precats as well. I thought that it might just be due to oil dripping on them, but it looked like maybe there was a leak there? Is it a common problem to have the precats get an exhaust leak like that. Keep in mind that this is a Texas car so although I am not ruling it out I doubt it is due to rusting.

They rust from the inside out . short trips cause condensation to form . You don't have any HUMIDITY in Texas right ?

The rusting/exhaust leaking happens after the precats and shields.
It starts at the brackets in front of the 2 into1 cat.

Re: SVX is smoking on precats

The engine sounded a lot smoother especially in the mid range. It smoked for a good 10 minutes or so which is how I noticed smoking in the engine bay lol. Well I guess I will get those pipes replaced. All in a years work . I am about to start taking this car apart and fix all the wrongs. Should be fun!
