So ive narrowed it down between 2 catbacks now either the invidia or the tanabe g blue looking for some opinions anything from better sound to most power thanks!

 

sound in opinionated...you can try youtube but take the sound with a grain of salt
as far as power as long as they are both 3" with no taper, they'll be similar

for more info between the two try searching each

we have plenty of exhaust info here
