tt exhaust has mandrel bends. You can get a stock tt catback pretty cheap from someone. It will give the na a little more growl. Removing the cats will make you lose torque on an NA. I learned from experience, and bought high flow cats to fix. Anyone that says differently is just obsessed with the extra noise and pretends not to notice the loss of torque, cuz it will be a little peppier at higher rpms without them. It will f' up the low end though, and make it feel like a damn civic below 3k rpms.
