Talked yesterday to guy that’s helped some with my intake & is working the 3rd set of DCI 5s. He mentioned as someone here did as well swapping the collector. He said go with a longer 4” collector. I can’t go much longer & still make it fit but it’s an option. Mine & my dad’s cars were supposed to be identical builds but my his headers hit my steering so I can’t try his.
