Cat Back Exhaust Questions

Magnaflow is good stuff. I have their high-flow cats on the Camaro. But I would never do an exhaust on the Malibu. It will add maybe 2 HP if you're lucky and will not sound good with either engine. I had a GT-R catback on my old G6 GTP for about a week before I yanked it and sold it on Ebay. Sounded like a tractor.

I like the sound of this. They deleted muffler and that was it. I like it.

See to me, that sounds absolutely horrible and unrefined. Also, under load that is gonna sound like a farm tractor.

I got the Magnaflow kit and it sounds awesome.... its deep enough for when you get on it and a low rumble when you are idling.... I get tons of Compliments from ppl at car shows and when i am driving around town... check out the vid

While I still am not a fan of any exhaust on GM V6's, I will have to admit it is the best sounding cat-back I have heard so far on a 3.6....

Do you really notice such a difference in HP? If so what would be in your opinion would be the slight change as I'm naturally curious.

You will not notice the 2-3 hp you gain from an exhaust.
