ive had these on my 03 se for 3 months and since then i havent notice any power difference. all it does is make ratteling sound from the heat shield. is there any point of getting these for 03's. cuz i heard that stock cat is just good as the after market cats. what u guys think?

 

Thats what I heard too but I have 75K miles on my rider and I will get a RT cat come tax time!
