Has anybody heard of the 3 inch system from magnaflow? I'm looking at getting it and I wanted to know if anybody had one on youtube and if I would get any hp gains. I know it isnt but half inch bigger than stock, but wanted to ask.

You might actually lose power with the 3inch system. They have a 2.5 inch catback system. 2 of them, one with the regular axle backs and then one with the magnapacks that are on my car. The pipes are mandrel bent. Over the axle the pipes are not crushed at the bends and the angles are not as sharp.

You can hear my car in my sig, click on the link new vid. you can also go to mangnaflows site and listen to soundclips of all their exhuast.

If you get Maganaflows, then go with the Magnapacks, because the regular Mags are too quiet imho.

i have the 2.5 h pipe and 3 in axel back magnapacks they sound alright but bad drone at 65 to 70 mph.dont have a sound clip or dyno run tho.

my local tuner put the 3" system with the magnapacks on their test car, because they plan on BIG horse power in the future, so they wanted a larger exhaust size (all the way throughout the car though, bigger headers, etc)
