Hey guys so I currently have a 2013 WRX Hatch with an Invidia catless down pipe and a stock cat back exhaust with a Torqued Performance Stage 2 tune. I was thinking of buying a catback exhaust. With the catless down pipe, the turbo's spool and blowoff are quite defined. I merely wish to amplify this sound and the iconic boxer growl. I don't want anything raspy, just throaty and semi loud. Ive looked at videos of different set ups but I am not sure how much justice these videos do to the sound. I don't know a whole lot about cutbacks in particular. I am between the COBB catback, the Invidia Q300's, Greddy SP Elite, Turboxs, or the ARK GRiP. Which one is the best in your opinions?Additionally, will adding a cutback exhaust increase the chances of boos creep or over boost? So far I have no experienced any of these complications, but I was wondering if that was due to the stock cutback. Thanks a lot! Look forward to reading your responses!
