Hey I am still on the hunt for a Nismo Exhaust. I have an option to buy just the Muffler and Y-pipe from someone, but then I'd need to find a Mid-pipe. What would be the difference between the Nismo midpipe with the S-tune exhaust...and a Megan Racing Midpipe? Will it change the sound of the nismo, make it drone, etc? Basically I'm looking for a replacement for the Nismo Midpipe, since the seller doesnt have one.

I'd appreciate any help. Thanks!
