You’ll need a little extension pipe to mount on pregen. Or if you measure carefully, you can chop off mufflers near inlet and reuse factory pipe. Assuming OD of pipe matches up with ID of those mufflers. Otherwise auto-stores have adapters that can bridge them
Yeah, for 250, you’ll probably be want slower flowing exhaust than 1200. Perhaps add an insert to end-caps. Anyone remember Supertrapp exhausts?
