Im looking for a good way to upgrade my exhaust but I dont want to drop $1200. Looking for a good cat back system. Borla would be nice but it seems like borla doesnt make just a cat back. But it does refer me to magnaflow. Are they the same thing basically? Im open to different suggestions too. I just want to keep that godly g35 humming sound but also make it louder while gaining a few ponies.

 

Test pipes, High-flow cats, or MD art pipes are your best bet for keeping the stock stone and gaining a few hp!

 

Could you post some good links on some cats and test pipes?

 

Your best bet would be to check under marketplace under Vendors, best deals for these kinds of parts are there.
