Hi all. New here but thought I'd drop some info on the V6 cat back. Hope I can get some comments from this group to help out.
Here's a couple of post I made on another board for those who haven't seen them.
I got a message from Magnaflow tech about a month ago asking if I'd be interested in loaning them my G8 V6 to prototype, install and test their new V6 cat back system.
Well last Monday, 8 Dec, I drove down to their shop and dropped off the car. The only mod to the engine so far has been the oil change to royal Purple. Other than that, it's stock which is what they wanted. I was suppoed to pick up the car today but I talked to them yesterday and they need it for another week.
They said that the exhaust sounds great outside the car but that they have a problem with interior drone and are building a new muffler to try and fix that problem. I ha dtold them that this was my family car and so I was concerned about interior noise and they have taken that to heart.
They will also be running the car on the dyno to get some numbers but have only done the base line so far. They have to get the exhaust right first before they put it back on the dyno.
Base line numbers were 196 HP and a little over 220 Tq. I was a bit supprised at the TQ number being that high based on the HP numbers. But that's a good thing. We'll see how it all turns out when they are done.
I'm thinking they should have systems ready after the start of the new year. I'll keep everyone posted as I find out more. Can't wait to get the car back and see how it is. I'll have about 110 mile ride home when I get it to evaluate it. The guys at Magnaflow are really great people and have worked with me to meet both of our goals.
