Just replaced ours with the Aero Turbine 5050XL. Not sure if the ISC (assume 350 is the ISC?) also has a 5" pipe? If not, then the 4040XL. Our chrome tip was in pretty good shape, and they were able to re-use that. It is a bit louder when going by bridges or side concrete walls, but I did not notice any significant change in noise from the driver seat. We have a total of 20 mils on it, after driving it home from the shop. So, no opinion on if it will allow a bit more breathing from lower back pressure. We'll see, as that is why we put it on, our OEM muffler looked good (I gave it to the shop as they had a gent that they felt they could use it for. Save him some money, as they will charge him labor only, and I like to see it being used down the road:)!
Best of luck!
