The bassani was $400 and the Mac was like 150 so he saved money and he loves the pipe. The MAC was easier to install then the Bassani also. I do not know much about Magnaflow but I am extremely happy with MAC. And so are my friends.

Good luck with you choice.

You're talkin about x pipes,i'm talkin about the cat back.What will give me more power an off road x pipe or a cat back?And will the x pipe change the sound for the worse?I heard that an off road x pipe with a cat back will produce alot of resonating and i don't like that.

With Magnaflow you'll have to get the catback welded. I love the sound of my Magnaflows and haven't heard about any quality problems with them or had any myself.

I contacted the seller on ebay,and he said it's bolt on.Why do you say i'll have to weld it?
