Magnaflow Catback issue Has anyone ever had an issue with a new Magnaflow Catback being clogged or something? I just had my car dynoed and the car pinged like crazy. We backed off the timing to 20 degrees to combat that and only made 360rwhp. We opened up the cutouts with no other changes and it gained 100 more hp. Once we added the timing back in it was close to 500rwhp. I never had any issues with my Corsa except for being too loud. I was going to contact Magnaflow tomorrow to see what they said but I wanted to see if anyone else experienced this before. The motor is a 416 stroker with a 4L60e.

I've never heard of such a thing, but if there was a manufacturing failure and the inner tubing was absent, dislocated, or collapsed, sending the exhaust into a mass of fiberglass packing, I can see how your kind of problem might occur.

I guess one of my Cats from my Kook's y-pipe took a dump in my exhaust. This is all what came out . It was so compacted in there I am suprised it even ran...

Hence why I'll never use cats. I've had them come apart in the past and seen others go through the same crap.
