Yea there is an big sound difference. Only thing I should say is since you have an 07 im assuming that you have only 2 stock cats(one on each side). I had 4 total and cut 4 off and replaced em with 2 Magnaflows. Im sure it should still make a difference just maybe not a much as mine did. I say go for it you can get the cats for about 75 bucks a piece last time a checked.
