Hey guys,

I recently picked up a 07 IS350 and the previous owner did a resonator delete and secondary cat deletes. The car also has the F Sport Axleback installed. I want to remove the drone and I was thinking maybe putting in a resonator back onto the car to quiet it down. I was looking at the Vibrant 1141 2.5" Ultra Quiet Resonator. It seems to have a decent amount of positive reviews on Amazon. Now my question is which piping is compatible with my car - do I get the 2.25, 2.5 or the 3?

Thanks!

2.5" if you're sticking with the stock sizing. The vibrant ultra quiet resonator is great! I'm sure you'll like it
