anyone have a video with sound of what a magnaflow cat attached to a stock muffler sounds like on a 2.8 or 3.4PR?

Yes as a matter of fact I do. In the summer of 2011 I made a new intermediate pipe with a Magnaflow 53004 converter and some 304 stainless tubing from Burns Stainless. Here's what it looked like just prior to installation:


And here's what it sounds like (with an OE muffler): http://www.youtube.com/watch?v=f5LeZ8vjnxc

Thanks. Nice sound. I'd like something with more attitude without being loud. Seems like magnaflows have nice sound.

Very nice work and sound. Too bad that you need a cat though. They can be very restrictive.

Dennis,
I don't have to have a cat, but I keep thinking without one, it will be too loud and with a stock muffler and no cat they don't sound very good. my stock muffler is in excellent condition so hate to not use it. I'm not concerned about local noise ordinance, just don't want it too loud inside the car.

Dennis that is really not the case today. I had a straight pipe on my car for 10+ years before I put a converter back on it. That Magnaflow converter has not reduced the performance of the car in any way, but it has nearly eliminated the smell of the non catalyzed exhaust.
