Hi, im trying to decide on an exhaust system i have narowed it down to 4 inch Magniflow or Rip . The Magniflow system is stainless from the rpm outlet .com it seems like a good deal they say its 14 guage t-304 stainless . the system with a resenator tip would cost me $430. 00 shipped . The Rip system is 16 gauge aluminize coated steal it looks like its on sale for $298. 00 but i would have to add a tipp and shipping to that. They both seem to have good reveiws here but i see more poeple runing Rip systems and i have seen they have excellent costomer service. The stainless system seems like a longer lasting setup what do you think
