Which one has a better, deeper tone to it? I used to have the greddy sp for my HOT!! honda civic, lol save it! But i was waundering which one would sound better on the 7, i like the looks to both so thats not a factor either.

 

I have the Greddy and numerous people say it has a lot deeper tone to it than most.

 

i like the look of the SP but i also like the looks of the M2 dual.
