Exhaust Help!
I recently installed the hpf gen 2 exhaust and am loving it however in about 3 weeks after installed I find myself with a collapsed cat.. my shop told me im better off with catless dp's but I have read that with hpf exhaust+catless dp's you basically need ear plugs for the highway.. my question is should i just change exhaust and avoid the headache or is there a way to add a second resonator to the exhaust and mellow out the sound.. any advice or help will be greatly appreciated

collapsed cat? clogged ? ... they make high flow catted dps, search for that. or yeah put in catless dps and if it's "too loud" which it shouldn't be, any good exhaust shop or welder can add in a resonator or 2 or whatever you want
