I always hear how getting a custom Y-pipe will make your exhaust note sound raspier / ricey. What's the best muffler to combine with a custom Y-pipe to get a deep, rich exhaust note? I'm talking about one where if you give it a little gas on the freeway you get a solid, deep note, and when you let off the gas, you get the same not reversed.
I had a magnaflow street series on my 3rd gen and got this kind of note - how are magnaflows on 4th gen?
