comparing midpipe on is250, 350 and Is-f
 

Are these all different, or can they be swapped out. Im just curious, if i can get the is-f into my 250 or will getting the midpipe from a 350 any better than the 250.

still not sure of the sound difference a megan mid-pipe will have all the videos sound kinda like my car now with just f-sport exhaust.

any help guys?

The sound would drastically change if you cut off your resonator or get an aftermarket Mid Pipe
