So I'm looking at getting an upgrade to my exhaust. As much as I would love the ATAK from Borla, I can't justify spending $1600 on it. Considering all it really does is delete the mid mufflers and replace the resonators, I figured I would go cheaper and just get mufflers from them to replace the resonators and delete the mufflers my self. They have a decent amount of choices to choose from though. I've seen some videos on older models and on other cars of the ProXS and the XR-1 but I wanted to see if anyone here has them on a newer RT like mine. I love the sound of the ATAK and want a good loud growling sound like it gets and want to know if anyone can recommend one of these two muffler styles. And before anyone says anything no, I'm not going to straight pipe it because I just don't like the sound. I have driven several one's that are straight piped and it just isn't for me.
